ABSTRACT
A MICROPROCESSOR CONTROL SYSTEM
FOR UHF TELEVISION TRANSMITTERS
by
Donald Richard Thompson II
Master of Science in Engineering
This graduate project describes the analysis and design of a
microprocessor control system for UHF television transmitters.
The
controller is designed specifically for the transmitter facility of
KWHY-TV at Mount Wilson, California.
Hardware includes a single-board computer, video display, printer,
power supply, and the appropriate supplementary I/0 and interfacing.
Software is written in Intel 8080 assembly mnemonics, with additional
Z80 instructions inserted to utilize Mode 2 interrupt structure.
Code
resides in 8K of EPROM, with data storage provided by lK of RAM.
System features include automatic logging of meter data, postfault restoration of carriers, and continuous monitoring of selected
transmitter parameters.
A diagnostic software mode is provided to
assist in performance of routine transmitter maintenance.

CHAPTER 1
INTRODUCTION
1.1 Objectives
High power UHF television transmitters are often situated in remote locations and manned by a single operator.
This operator must
periodically check and log the transmitter operating parameters, perform routine maintenance, and be prepared to rapidly diagnose and
correct any abnormal conditions or faults.
Modern television transmitters are generally well-designed and
reliable, and incorporate many automatic control features to prevent
any serious transmitter damage in the event of a catastrophic fault.
These control features generally do not assist the operator in restoring normal transmitter operation after an automatic shutdown or utility
power failure.
Some transmitters provide no warning signals of margin-
al operating conditions.
A lack of audible alarms results in the
possibility that the operator, while engaged in activities away from
the transmitter control point, may be temporarily unaware of such
serious events as off-frequency operation, improper power output, or
even complete loss of the aural or visual carrier.
The objective of this project was the design and construction of a
microprocessor controller for the UHF transmitter of KWHY-TV, at Mount
Wilson, California.
The controller was to include the capabilities
listed in Table 1.1.1.
1
Table 1.1.1
Desired Controller Functions
1. Automatic logging of FCC-required parameters {visual/
aural power, klystron beam voltage/current, deviation
from assigned carrier frequencies, etc.).
2. Continuous monitoring of critical transmitter parameters, with CRT display of the nature and duration of
irregularities.
3. Automatic restoration of carriers after a utility
power failure or correctable fault.
4. Transmitter control and observation of operating
parameters from a centralized point.
5. Diagnostic subroutines to assist in maintenance of
transmitter subsystems.
Actual measurement of FCC log data is performed by existing KWHY
equipment, which has been subjected to type-acceptance and proof of
performance evaluation.
The controller function is to read the data
and print it in an acceptable log format.
The controller also must
interpret the data to determine if it lies within an acceptable range.
Other system inputs are obtained directly from the transmitter hardware.
While the controller is specifically for the Townsend Associates
TA-55 NV transmitter, an attempt has been made to make the software and
interface devices as general in nature as possible.
1.2 Typical UHF Television Transmitter Layout
A typical UHF television transmitting facility will include the
following subsystems:
1. Microwave receivers and antennas
Program information is generally received at remote
3
transmitter sites by means of primary and secondary studiotransmitter links (STL).
Automatic switching to the backup
link upon failure of the primary is desirable.
In the event of
a complete loss of program feed, automatic switching to an al=
ternate video source (test pattern generator) would prevent the
potential difficulties associated with prolonged transmitter
operation at a reference black (high power) level.
These auto-
matic functions have not been included in this project, as they
may be implemented more efficiently by discrete logic.
2. Processing amplifiers, correctors, and video IF unit
The processing amplifier allows the operator to set video
waveform parameters (AGC, sync, burst, chroma, setup) to their
proper values.
The processing amplifier and phase and linear-
ity correctors are used to precorrect the video signal for
subsequent distortion encountered in the video exciter and the
klystron power amplifier.
The processed video is applied to
the video IF unit, where low level DSB modulation is accomplished at a suitable IF.
The DSB signal is processed through
a VSB filter which properly shapes the upper and lower sidebands.
KWHY-TV also uses encoding devices prior to the aural
and visual IF units to generate signals for over the air subscription television (STV).
Incidental phase modulation (ICPM)
correctors may also be inserted in the video path.
3. Upconverter unit
The upconverter shifts the visual and aural IF signals to
their final carrier frequencies, prior to input to the klystron
power amplifiers.
KWHY-TV broadcasts on Channel 22; the
4
visual and aural carrier frequencies are 519.25 MHz and 523.75
MHz, respectively.
4. Klystron power amplifiers
Modern vapor-cooled klystron amplifiers (such as the
Varian 950 series) are capable of delivering in excess of fifty
kilowatts output with input drive of less than one watt.
ciency is on the order of thirty percent.
Effi-
High voltage and
current levels are required to supply the klystron, and these
levels must be periodically monitored to verify proper operation and to satisfy requirements of the FCC.
As supplied by the manufacturer, the amplifier system
normally includes devices designed to remove power from the
klystron if certain operating limits (beam voltage/current,
focus, temperature, VSWR, etc.) are exceeded.
Interlocks are
provided to insure that cooling water is present, and to prevent operator contact with high voltage points inside the
enclosure.
Circuitry is provided for control of modulating
anode bias voltage and magnet current, and to display such
parameters as water flow rate, heater and body current, and
beam voltage and current.
5. Limiter/compressor and aural IF unit
Audio program feed from the STL may be processed through
a limiter/compressor to insure that a suitable level is present
at the input of the aural IF unit.
The IF unit provides an
adjustable attenuator and a high pass filter to produce the
standard 75 microsecond preemphasis characteristic.
cessed audio is applied to an FM modulator.
The pro-
The FM signal
5
modulation (at the output of the upconverter) is defined to be
100 percent at ~25 kHz deviation.
Calibration of the FM modu-
lation monitor is generally accomplished by the Bessel null
method, utilizing a spectrum analyzer and crystal-controlled
audio oscillator of 10.396 kHz.
6. Diplexer, antenna, and dummy load
The outputs of the aural and visual klystron amplifiers
are combined in the diplexer to produce the composite television signal.
The diplexer inputs and outputs are routed
through a waveguide patch panel, which allows the signals to be
transmitted to either the broadcast antenna or to a watercooled dummy load for testing or power calibration purposes.
7. Heat exchanger
The heat exchanger system pumps distilled cooling water
to the klystrons, magnets, and dummy load.
The return flow is
cooled and recirculated.
8. Peak detectors and power meters
Samples from the klystron outputs are supplied to RF peak
detectors, which in turn drive ordinary ammeters as an indication of relative power output.
Calibration is accomplished at
values of 80, 100, and 110 percent of authorized power output,
by means of careful measurements conducted with standard input
signals, dummy load, and RF wattmeter.
Commonly~
a series
potentiometer is used to set the ammeter scale at the measured
100 percent output.
External markings are placed on the meter
face to indicate the measured 80 and 110 percent points.
The
external marks typically do not agree with the linear ammeter
6
I
scales due to the nonlinear characteristics of the RF peak
detector.
9. Monitoring instruments
All broadcast television facilities include certain
instruments to monitor the quality of the transmitted
sign~l.
FM deviation monitorss frequency monitors, spectrum analyzerss
vectorscopes, and high-quality demodulators and waveform monitors are essential equipment.
Additional gear will often be
present, such as an FM modulation analyzer, distortion analyzers and line frequency monitor.
10. Power supplies
High voltage klystron power supplies are often the most
troublesome portion of the transmitting system, particularly
at installations located at high elevations.
Switching is
typically accomplished by means of a three-phase vacuum contactor at the regulated 440 volt input to the high voltage
transformer.
The transformer output commonly exceeds 20 kilo-
volts, and feeds a three-phase full-wave rectifier system and
single section choke-input filter.
A step-start circuit is
often employed to temporarily insert a resistance in series
with the filter capacitor, to limit the large initial surge
current.
The high voltage conductors utilize special insula-
ting materials and are heavily shielded.
The conductors are
terminated with special stress relief cones and wrappings to
reduce corona.
The high-voltage enclosures must be kept as
clean and dust-free as possible, if arcing is to be prevented.

CHAPTER 2
PRELIMINARY CONSIDERATIONS FOR CONTROLLER DESIGN
2.1
Definition of Tasks
The first consideration in controller design is: how many tasks
must the controller perform, and how rapidly must they be accomplished? Section 1.1 listed five primary controller objectives, which are
considered individually below.
1. Automatic logging functions
FCC regulations permit a maximum interval of three hours
between log entries of transmitter parameters.
The minimum
possible interval between entries will be limited by the speed
of the printer mechanism, if the controller is not required to
continuously store the accumulated data.
A default logging
period of one hour has been chosen here, with the option of
operator selection of a shorter period by keyboard command.
2. Continuous monitoring of transmitter parameters
The highest priority controller inputs are the signals
indicating the status of the klystron beams.
If the beams are
down, obviously all other inputs are irrelevant.
The beam
status signals should therefore be the most frequently-checked
inputs.
A meter-reading scheme has been selected in which the
analog meters drive voltage-controlled pulse-width modulators
(PWM).
The controller determines the meter reading by measur-
ing the duration of the PWM output pulses.
7
Since several
8
meters must be read, a system has been implemented in which
the selected PWM signal is periodically sampled, and the interval between samples is primarily occupied by checks of the
beam status signals.
The arbitrary design goal was that all
meters should be read and interpreted at intervals of less than
one second.
To simplify the software and maintenance of the
controller, meter-reading functions are suspended during data
transfer to the CRT or printer.
A loss of beam signal will
interrupt data transfer until two automatic attempts to restart
the beams have been accomplished.
3. Automatic restoration of carriers
Upon a loss of beam signal, the controller will sample the
utility power line to determine if the beam loss is due to a
power failure or system fault.
In the event of a system fault,
two attempts will be made to restart the beams.
If a power
failure has occurred, the controller will determine when power
has been restored and wait a suitable period to allow for the
dissipation of line transients before attempting to restart the
beams.
4. Transmitter control from a central point
Controller software is designed to include three modes:
conversational, control, and diagnostic.
The conversational
mode allows the operator to turn the transmitter on and off,
start or drop the klystron beams, set the clock, and display
current meter readings or transmitter status on the CRT display
or printer.
The control mode is the normal operating mode
where the controller continuously checks the input signals for
9
irregularities, signals alarm conditions, prints log data, and
attempts to restart the beams if a failure occurs.
In the
control mode, the controller ignores all keyboard entries except for the log data function and the command to exit from the
control mode.
The diagnostic mode allows execution of specific
stored subroutines to assist in the adjustment of relay timing.
5. Diagnostic subroutines
The controller diagnostic subroutines will be dependent on
the specific transmitter hardware.
This project includes a
routine to measure the opening and closing of four sets of
time-delay relay contacts.
2.2
I/0 Requirements
The second controller consideration is: how many lines of input
and output are required? The necessary I/0 lines have been specified
and assigned to 8-bit ports as indicated in Table 2.2.1.
Several spare lines have been reserved in anticipation of software
modification and future expansion.
Note that the four address lines of
Output Port 2 serve a dual purpose: selection of one of sixteen PWM
inputs from analog meters at line 4 of Input Port 2, or the selection
of 4-bit BCD data from one of eight frequency meter digits on lines 0-3
of Input Port 2.
This permits the frequency meter to be read while
simultaneously sampling the PWM output of the selected meter, providing
more rapid system throughput.
2.3 A/D Conversion Technique
At this point, the sampling period of the meter PWM inputs should
be considered.
A stable sampling period should be employed, small

enough to provide adequate resolution of the PWM pulse duration.
The
interrupt-driven clock has been selected to provide regular updates at
a period of ten milliseconds.
If the various PWM pulse widths are
properly selected, the controller can determine meter readings by a
simple binary to decimal conversion of a stored count.
This implies a
certain complexity of the meter/PWM interface hardware, but this
approach was considered preferable to software manipulation of data
which has originated from a nonlinear analog source.
11
As the acceptable range of a single meter reading is small, software may be implemented to allow high resolution of readings which fall
within that proper range.
Assume that the PWM provides pulses which
may range from 50 to 100 counts of the sampling period per reading, for
a 2:1 ratio.
A one percent resolution for power meters is sufficient,
since the analog meter has only three calibration points.
The follow-
ing process would be followed to allow readings to be obtained ranging
from 70 to 120 percent:
1. Lines 0-3 of Output Port 2 transmit the proper meter address
to the PWM multiplexer, which selects the desired PWM power
meter input.
2. After a short delay, the proper PWM signal appears at line 4
of Input Port 2.
3. A count of 20 (0014H) is stored in a register pair.
The con-
troller waits until a new pulse appears, then samples the
signal at a fixed rate and increments the register pair with
each sampling until the pulse is completed.
If 80 samplings
occur, the register pair will contain a count of 100 (0064H).
4. Power meter alarm limits have been defined here as 95 and 105
percent.
Thus, if the final register pair count is less than
0060H, or greater than 0068H, a minor alarm is initiated and
data is sent to the CRT to indicate which meter has provided a
bad reading.
A listing of the selected address, initial count,
alarm limits, decimal range of measurement, and resolution for
six meters is indicated in Table 2.3.1.
The meter-reading process should be started upon conclusion of a
12
clock update, and must conclude prior to the next update.
Since the
clock interrupts occur at an interval of 10 milliseconds, the PWM
repetition rate has been selected as 330 Hz.
With a 90 percent duty
cycle limit, the maximum pulse duration is 2.7 milliseconds.
With the
2:1 ratio assumed, the minimum pulse duration is 1.35 milliseconds.
The sampling period must be 27.0 microseconds to allow 100 samples
during the maximum pulse.
A flow chart and 8080 assembly listing of a
27 microsecond sampling routine are shown in Figure 2.3.1.

With the given software development tools, it was apparent that
the chosen CPU had to execute code generated by MOOS from Intel 8080
assembly language mnemonics.
However, the Zilog Z80 CPU has the
advantage of Mode 2 interrupt structure, while retaining the ability
to execute 8080 code.
bly language.
It was decided to use a Z80 CPU and 8080 assem-
The appropriate Z80 code required to initialize the
Mode 2 interrupts could be inserted into the 8080 assembly language by
means of Define Byte (DB) mnemonics.
The memory capacity of the software development system is also an
important factor.
While it was anticipated that the final controller
code would fit into an 8K space, the assembly language required to
generate that code requires a much larger memory space.
The 36K de-
velopment system used was unable to accommodate both the MOOS and the
entire assembly language program, so that multiple disk files were
necessary.
Complexity arises when software must be debugged in blocks
which are indistinct, as it is often necessary to call a subroutine
which is not on the same disk file, or has not yet been written.
This
difficulty may be overcome by several methods, but should be taken
into consideration in the early stages of software development.
The software designer may save time by using or modifying available public domain software.
Several portions of the operating system
for this project were adapted from the IMSAI 8080 Self-Contained
System, Revision Two. 1 The status of much available software is unclear, however, and the designer of software for resale must be aware

of the legal implications of adapting the work of another person.
It was decided to utilize a commercial CPU board for the S-100
bus, so that it could be initially tested in the IMSAI mainframe.
The
SBC-100 Single Board Computer, manufactured by SD Systems, was an
acceptable choice.
The SBC-100 includes the following features:
1. Z80 microprocessor
2. 1K RAM
3. 8K EPROM capacity (using 2716 EPROMs)
4. synchronous/asynchronous I/0 interface
5. software programmable baud rate
6. 8-bit input and output ports (one each)
7. four channel counter/timer (CTC) using the Mostek MK3882
8. four maskable vectored interrupts, one non-maskable interrupt
The CTC may be used to generate both the 16X USART clock and the
periodic interrupts for the real-time clock.
The USART may simul-
taneously input serial data from the keyboard and output serial data to
the printer.
The 1K RAM is sufficient for the stack and storage re-
quirements of the controller.

acteristics: a hardware cursor (to eliminate driver software), and I/0
mapping (to facilitate initial testing in the IMSAI mainframe, which
already contained a memory-mapped video board).
A suitable product was
obtained in the SSM Microcomputer Products VB2 Video Board, which includes the following features:
16
1. 64x16 upper case display
2. hardware cursor, line feed, carriage return, backspace, and
clear-screen functions
3. selectable black on white or white on black display
4. full-interlace scanning
5. adjustable margins and character widths
6. full duplex interface
7. driver for external tone signal
8. one 8-bit input port
2.6
Keyboard
The George Risk Industries GRI 756 Keyboard was selected from
the available spectrum of keyboard products.
The serial output option
was implemented by adding a USART and baud rate generator to the components supplied in the kit.
The serial option was preferred due to
the high ambient RF levels at the transmitter site, and the necessity
of a long cable between the keyboard and controller enclosures.
The
data rate was selected as 300 baud.
2.7 Additional Hardware
It was decided to postpone design of the power supply until all
system components were fully specified.
Likewise, design of the re-
maining I/0 interfacing was considered a trivial task which could be
postponed until the controller software was approaching final form.

PWM Multiplexer
A schematic of the PWM multiplexer is shown in Figure 3.2.1. -This
device allows one of sixteen PWM signals to be selected by lines 0-3 of

The pulse width modulator of Figure 3.3.1 is driven by an analog
signal to produce pulses ranging from 1.35 to 2.7 milliseconds.
pulse repetition rate is 330 Hz.
The
The input stage is a Class 2E 2 low
pass filter with gain -R2/R1, cutoff of 20 Hz, and damping factor of
0.707.
The next stage is a level translator which drives the control
input of the pulse width modulator.
Potentiometer R8 adjusts the repe-
titian rate.
For linear input signals, R1 may be a fixed resistor.
For
non~
linear input signals from power meters, the interaction of R1, R5, R6,
and R7 allows the monostable portion of the 556 timer to be operated in
the nonlinear region (near the control voltage limits) for best matching of the meter characteristic.
See Appendix F for additional data on
component selection, and Table 3.5.1 for a list of component values.

The circuit is simplified by use of a high-Q induc-
tor in the input band pass filter.
Narrow bandwidth 567 tone decoders
detect the two discrete frequencies.

3.9 Printer Interface
The SBC-100 USART is interfaced to the printer by means of a 20 rnA
current loop (see Section C.5).
There is no provision for checking the
ready status of the printer in this design, although modification of
the SBC-100 could make this possible.
The controller software provides
for the transmission of a series of null characters after each carriage
return, to allow for return of the print head.
With certain printers
it may be necessary to insert an initialization routine for the printer
before any data transmission occurs.
The user should consult specific
printer data to determine if a printer initialization is required, or
if the sequence of the CRLF subroutine should be reversed.

3.10 Relay Interface
The logic signals of the controller are interfaced to the UHF
transmitter by means of relays, as most transmitter control lines are
120 VAC.
Figure 3.10.1 indicates the relay interface requirements of
Output Ports 1-3.
The Diagnostic and utility power interfaces for

3.11 Exciter Interface
The Exciter Interface allows the controller to interrupt the RF
drive to the klystron amplifiers prior to raising the beams.
There
is some controversy as to whether this procedure is really necessary,
particularly when the klystron is already at operating temperature.
The RF drive may be interrupted by opening the contacts of a coaxial
relay, or by disconnecting the AC input power to the exciter.
Some
modern UHF exciters have separate AC inputs for the crystal ovens and
drive circuitry, which makes the power interruption method quite simple.
The Exciter Interface of Figure 3.11.1 uses this technique, and
includes a Bypass switch to quickly disable a controller interruption
in the event of malfunction.

3.12 Power Supply
The power requirements of the controller are: 8VDC @ 6A, +18VDC @
1A, and -18VDC @ IA.
Figure 3.12.1 is a schematic of a power supply
which exceeds these requirements by a substantial margin.
The supply is normally powered by 120VAC, and includes batteries
to maintain controller operation during power outages.
Automobile
batteries have been used to allow for additional connections to +28VDC
emergency lighting circuits which draw substantial current.
The bat-
teries are trickle-charged at a 40 rnA rate during normal AC operation.
Nickle-cadmium cells may be substituted if high battery capacity is not
required, with appropriate adjustment of the charging rate.
During AC operation, the ~18V supplies are generated by the full
wave rectifier and zener-controlled emitter followers.
The +8V supply
is half wave rectified, with an additional zener emitter follower.
Fuses are included in the AC line, and at each battery pair.

Initialization Routine
The Initialization Routine prepares the hardware of the SBC-100
for subsequent tasks.
The Counter/Timer of the SBC-100 utilizes the
Mostek MK3882 to provide four independent timing functions, each of
which requires initialization.
The Mode 2 interrupt structure of the
ZBO CPU also requires several steps of initialization.
The flow chart
of the Initialization Routine is indicated in Figure 4.1.1.

Control returns to the Warm-Start Entry Point upon execution of a
keyboard command or upon return to the conversational mode from the
control or diagnostic modes.
A new keyboard command is accepted and
subroutines are called to check the entry against the list of legal
commands and transfer execution to the appropriate point.
The stack
pointer and status flag are reset upon each return to the Warm-Start
Entry Point.

The PONE subroutine is called from the Control Mode to check the
status of signals at Input Port 1.
The PONE flow diagram is shown in
Figure 4.4.1.
4.5 Subroutine BEAM
The BEAM subroutine checks the visual/aural klystron beam status
signals at Input Port 1.
If one or both beams have dropped, a check is
made of the utility power signal to determine if the cause was a system
fault or power failure.
In the event of power failure, the duration of
the outage is measured and an approximately equal delay is inserted
after restoration of power to allow the klystron heaters to recover
before restart.
If the dropout was due to a line transient or system
fault, beam restart is attempted immediately.

Two attempts to restart
If restart is successful, data is transmitted
to the printer and CRT to indicate the nature and duration of the problem.
If two restart attempts fail, execution is transferred to the

Conversational Mode.
The BEAM flowchart is displayed in Figure 4.5.1.
4.6 Subroutine ANNP
The ANNP subroutine checks the status of the visual/aural amplifier annunciator signals at Input Port 1.
Alarm conditions are set or
cleared as required, and appropriate data is transmitted to the CRT
display.
The ANNP flowchart is indicated in Figure 4.6.1.
4.7 Subroutine EBS
The EBS subroutine checks the status of the signal at Input Port 1
which indicates the presence of Emergency Broadcast System test tones.
Data is transmitted to the printer and CRT to indicate the duration of
the test.

4.10 Subroutine METER
The flow chart of Figure 4.10.1 indicates the process employed by
the controller to read analog meters by the PWM sampling method.
The
METER routine is called by other subroutines (VPWR, VKV, VAMP, etc.)
which load the required parameters (meter address, alarm limits, initial count) into RAM storage for use by METER.
In the event of a
modification of transmitter hardware which results in a new range of
meter readings, the controller software can be patched by a simple
correction of the initial count and alarm limit tables.
METER checks the NOPRINT flag to determine if the current reading
is to be output to the printer for logging purposes.
Output of error
messages to the CRT is unaffected by the status of NOPRINT.
See Sec-
tion 8.3 for the location of NOPRINT in the MOST Flag Byte.
4.11 Subroutine STATUS
The STATUS routine of Figure 4.11.1 is called by the transmitter
operator by pressing the Carriage Return key while the controller is
operating in the Automatic Control mode.
11
Subsequent depression of the
P11 key will output a data line to the printer.
Depression of any
other key will output a data line to the CRT only.
An intermediate
entry point of the STATUS routine is called in subroutine PTWO, when
the LOGDATA flag has been set by the Interrupt Service Routine.
The
LOGDATA flag is set at the start of each hour, and results in the output of a data line to the printer by PTWO.

4.14 Subroutine PTWO
The PTWO subroutine checks the status of the analog meters and
Belar TVM 3 Frequency Monitor.
Alarm conditions are initiated if any
out of range readings are discovered.
Visual amplifier readings are obtained by calling subroutines
VPWR, VKV, VAMP, and VFRQ.
Aural amplifier readings are achieved by
subroutines APWR, AKV, AAMP, and AFRQ.
These subroutines load the
proper alarm limits and initial count into RAM storage, prior to calling the METER subroutine to measure the selected PWM pulse duration.
See Section 4.10 for the METER routine description.
The PTWO flow
chart is shown in Figure 4.14.1.
4.15 Diagnostic Mode
The TA-55NV control functions are primarily determined by a relay
logic sequence.
Normal maintenance consists of checking and adjusting
the timing of the relay functions.
It was decided to make the diag-
nostic function into a general routine which simply reads the open or
closed status of four sets of relay or switch contacts, then prints
the time of any changes in the original status.
This allows the
operator to change the definition of the four diagnostic inputs at
any time, without affecting the existing software.
The flow logic of
the Diagnostic Mode software is indicated in Figure 4.15.1.

4.16 EPROM Routine
The EPROM Routine assists the programmer in transferring the
assembled controller software into the four 2716 EPROMs, in conjunction with the Micropolis MOOS.
The controller software, which will
eventually reside at OCOOO-ODFFFH, is assembled with offset at memory
locations 5000-6FFFH of the development system.
then assembled at 4000H and executed.
The EPROM Routine is
Messages are output to the
development system console device to lead the programmer through the
required steps to burn the controller data into EPROMs with the PB1
EPROM programming board. A sample listing of the console output is
shown in Figure 4.16.2.
The flow chart of the EPROM Routine is indi-
cated in Figure 4.16.1.
In addition to instructing the programmer, the EPROM Routine also
checks the EPROMs to insure that they are fully erased, and that the
programmed data matches the corresponding memory block upon completion
of the programming cycle.
If an error is encountered, a message is
output to the console device and the program is aborted.

CHAPTER 5
CONTROLLER OPERATING PROCEDURES
5.1
Command Summary
The legal Conversational Mode commands, and their effects, are
listed below:
AURD: Drop the aural klystron beam
AURU: Raise the aural klystron beam
AUTO: Exit the Conversational Mode, enter the Automatic Control Mode
BARK: Start or stop the Barker channel cart machine
CTVM: Switch to Commercial TV Mode
DATE: Display the current recorded date
DIAG: Exit the Conversational Mode, enter the Diagnostic Mode
DUMP start address end address: Display the hexadecimal controller
memory contents between the specified limits
EXCD: Remove exciter drive from the klystron amplifiers
EXCU: Apply exciter drive to the klystron amplifiers
HEAD: Print a new log heading
INFO: Display a summary of legal commands on the CRT
SETC: Set the real time clock
SETD: Update the current recorded date (the controller software
normally performs this function automatically)
STVM: Switch to Subscription TV Mode
TIME: Display the current time (24 hour; xx:xx:xx:xx )
64
65
VISD: Drop the visual klystron beam
VISU: Raise the visual klystron beam
XMTD: Drop the aural and visual beams, turn amplifiers off
XMTU: Turn on the aural and visual amplifiers
5.2
Initialization
When the controller is initially turned on, the error flag bytes
are cleared and all output ports assume a status of OOH.
This results
in an immediate switch to the Commercial TV Mode, if the transmitter
is already on in the Subscription TV Mode.
It is assumed that the
controller should not be powered-up if the transmitter is currently
on the air.
This condition could be changed by inserting a routine
to read the CTV/STV status and set Output Port 3 accordingly.
The
alarms will normally be powered from the controller source, and should
be cleared by the power-on reset circuit included.
The controller
will sign on in the Conversational Mode, request time and date data
from the operator, and be ready for subsequent commands.
The operator
should adjust the paper feed to the printer and use the HEAD command
to print a log heading prior to using the AUTO command to enter the
Automatic Control Mode.
Commands listed in Section 5.1 will only be
accepted in the Conversational Mode.
5.3 Control Mode Operation
The Automatic Control Mode is the normal controller mode when the
transmitter is on the air.
No error conditions will be detected if
the controller is not in the Automatic Control Mode.
Two keyboard
entries are recognized during Control Mode operation: Carriage Return
causes the controller to output a data line to the printer or CRT;
66
Escape (ESC) causes the controller to transfer to the Conversational
Mode.
When error conditions are detected during the Control Mode, a
single message is output to the CRT display upon the initiation of the
error condition, or upon its termination.
Messages are also output to
the printer if the error condition involves a loss of beams or a test
of the Emergency Broadcast System.
A data line will be sent to the
printer at the start of each hour, as determined by the real time
clock.
If the controller is in the Conversational Mode at the start
of a new hour, a printer data line will be output immediately upon
return to the Control Mode.
Exit from the Control Mode clears all
error flags, so that continuing error conditions will be reannounced
upon return to the Control Mode.
The clearing of error conditions
which existed during the Control Mode, and which were cleared during
Conversational or Diagnostic Modes, will not be announced upon return
to Control Mode.
5.4
Diagnostic Mode Operation
The Diagnostic Mode is entered from the Conversational Mode upon
execution of the DIAG command.
The on/off status of the four inputs
DIAGO-DIAG3 are sampled and all changes in status are output to the
CRT, along with the time.
The hardware interface provides a delay
so that relay contact bounce will not be interpreted as a successive
change in input signal status.
The Escape (ESC) is the only keyboard
entry recognized by the controller during the Diagnostic Mode, and
results in a return to the Conversational Mode.
