User Configuration:
The CA-101 is software configurable via a standard PC using HyperTerminal serial
communication using the NWI PA-100 programming adapter with special Duetsch connector. The
configuration menu is in the controller and does not need additional program installation.
Communication:
Communicating to the CA-101 controller is by means of a serial RS232 connection (generally
COM1 or COM2 on a PC). The CA-101 uses an industry standard DB-9 connector.
The serial communication parameters are as follows:
1. Baud Rate (bits per second):
115200.
2. Data Bits:
8
3. Stop Bits:
1
4. Parity:
None
5. Flow Control:
Xon/Xoff

Fig 2 Typical HyperTerminal menu screen showing default values
Shown in Fig. 2 is a typical HyperTerminal menu screen Menu showing the default values for each
coil. A description of each configuration item is as follows:
1. Valve Status: The valve status is either ‘Energized’ (meaning a PWM current is being
output to the valve in proportion to the input command signal) or
‘Deenergized’ (meaning the PWM current is not being output to the
valve).
2. Command Input: The command input is software selectable as Voltage 0-5vdc,010vdc or current 4-20ma. Pressing ‘v’ on the keyboard will select
voltage as control input. Pressing ‘i’ on the keyboard will select current
as control input. See Fig.2. The default value is Voltage.
3. PWM Duty Cycle: The PWM duty cycle is software adjustable from 0 to 100% by
pressing ‘C’ to increase the duty cycle or ‘c’ to decrease the duty cycle.
The default value is 100%.
4. Ramp Up Time: The Ramp Up Time, is software adjustable from 1 to 10 seconds in
0.1 second intervals by pressing ‘U’ to increase the ramp time or ‘u’ to
decrease the positive ramp time. Ramp time only affects increasing
current and is based upon the PWM duty cycle, or current limit – which
ever is the smallest.
5. Ramp Down Time: The Ramp Down Time, is software adjustable from 1 to 10
seconds in 0.1 second intervals by pressing ‘D’ to increase the ramp time
or ‘d’ to decrease the positive ramp time. Ramp time only affects
increasing current and is based upon the PWM duty cycle, or current
limit – which ever is the smallest.
6. Current Limit Max: The Current Limit is software adjustable from 0 to 2.5 amps and
determines the maximum current that is allowed to be output to the
valve. The absolute maximum value is 2.5 amp. Press ‘7’ to increase the
current limit or ‘6’ to decrease the current limit.
Note: The current level to the valve is determined by the command
input, PWM duty cycle or current limit – which ever is least
7. Deadband: The Current Limit is software adjustable from 0 to 100% and determines
the minimum current that is allowed to be output to the valve. Press ‘9’
to increase the current limit or ‘8’ to decrease the current limit.
Note: The current level to the valve is determined by the percentage
of the PWM duty cycle.
8. Dither Frequency: The Dither Frequency is software adjustable from 0 to 175 hz.
Press ‘F’ to increase the dither frequency or ‘f’ to decrease the dither
frequency.
9. Dither Amplitude: The Dither Amplitude is software adjustable from 0 to 10% of the
duty cycle. Press ‘A’ to increase the dither amplitude or ‘a’ to decrease
the dither amplitude.
10. Input Scale Factor: The Input Scale Factor is software adjustable from 0 to 200%.
This setting will multiply the command input value.
For example: If ‘Voltage’ is selected as the command input and the
maximum command voltage available is 4.8vdc (as provided by the user
voltage supply), a scale factor of 100% would allow the 4.8vdc to be
interpreted as 5vdc allowing full spool travel of the valve.
If voltage is selected as the command input and the maximum command
voltage available is 10vdc, a scale factor of 200% would allow the 10vdc
to be interpreted as 5vdc allowing full spool travel of the valve.
11. Command Voltage: The displayed value of the Command Input..
12. Output Current Level: The displayed value of the current output to the valve.
13. Coil Select: Selecting 1 or 2 will display the screen configuration menu for the
solenoid selected.
14. Save Settings: After configuring the selected solenoid, hit the enter key to save it to
the microprocessor. The controller will retain this configuration until
repeating the above process changes the values.
