View Touch Screen Monitor Installation Guide
Product Description
The Phoenix Controls View touch screen monitor is a
BACnet® MS/TP based networked user interface used to
display data and edit setpoint variables for vivariums,
hospitals, biocontainment spaces, operating rooms, patient
rooms, and nurses stations. The View can display data
from Phoenix Controls Traccel, Theris, PCM50X and
APM2 BACnet MS/TP devices, and 3rd party BACnet
MS/TP devices. The View is a 7" diagonal capacitive touch
screen panel that is flush mounted using a standard 90
cubic inches electrical box (Raco 942 or Thomas and Betts
H3BD341). It is intended to be installed in corridors
outside of critical environments to provide users with
information related to operating conditions inside the
space. The View can display up to 24 parameters
simultaneously and is capable of high and low limit,
change of state, and multi-state alarms. Each parameter is
capable of a user defined title and units of measure. The
View connects to the MS/TP bus and can be used to
display flow, temperature, humidity, air changes per hour,
offset, occupancy, and control setpoint variables available
on the MS/TP network.

Network Layout - Bus Topology
Network Cabling
Refer to Power and Signal Cabling on page 1 for cabling
requirements.
IMPORTANT:
The #8 screws and #10 washers are to be used with
the Raco 942 box, and the #10 screws and #10
washers are to be used with the Thomas and Betts
H3BD341 box.
NOTE:
•
Depending on the quality of the installation, it may be
necessary to reduce the baud rate to avoid intermittent
communications. The baud rate will be determined by the
slowest device on the network. Using a larger gauge wire
will not allow the maximum length of cable per segment
to be extended.
Faceplate - The faceplate of the View is designed to
snap-fit onto the unit allowing it to seal snugly against
the wall to ensure dust and moisture will not affect the
unit (IP54). If the View is mounted on a concrete
wall, additional sealing may be necessary to ensure the
IP rating of the device. Available options for the
faceplate are white, white with simulated stainless,
black, and black with simulated stainless. All faceplate
options have a gasket on the surface that contacts the
wall to seal out moisture and dust.
The quality of the cable, the number of
the devices, and the amount of data to
be passed across the bus influence the
practical cable length and
communications speed (baud rate).
Shield Grounding
Ground drain wire at single point earth (panel) ground.
Do not terminate on BACnet device grounds, but tie
drain wire through with wire nuts. Tape off drain wire at
other end of network segment.
Terminating resistors (provided by others)
Installation Overview
Matched resistors are required at the end of each network
segment bus and should be wired across Data (+) and
Data (-) communication terminals for signal integrity.
Use matched resistors with specifications of 120 1/4W
±5%.
Networking Considerations
NOTE:
BACnet MS/TP networks are very sensitive to proper
cable specifications, installation, and the number of
devices on a network segment. The cable quality and
length, together with network load, will influence the
speed of communication (baud rate).
•
•
Each BACnet network segment can accommodate a
maximum unit load of 32.
• Each View counts as 1 unit load.
• Other BACnet devices may count as whole
or fractional unit loads.
Phoenix Controls recommends limiting each network
segment to no more than 50 BACnet devices, even
when the total unit load is less than or equal to 32
If a View is first or last device on the network
segment, jumper J2 (View internal terminating
resistor) can be installed instead of using a physical
terminating resistor.
Segment length
4000 ft. (1219m) maximum per network segment using
recommended wire.
Devices per segment
Phoenix Controls recommends limiting each network
segment to no more than 50 BACnet devices, even when
the total unit load is less than or equal to 32.
Repeaters (provided by others)
Cable runs longer than 4000 ft. (1219 m) require
repeaters.

View Wiring Recommendations
Pulling Wires Into the Electrical Box
Due to the configuration of the View mounting bracket
and back cover, care must be taken to ensure that the
power and communication wires will clear the View
components when installed in the gang box. Refer to the
figure below to determine which knockouts to use to
ensure that the strain relief and wires will clear the View
once it’s installed in the wall.
•
•
•
•
•
To connect the wiring to the View, use the terminal
connectors. Use a small flat screwdriver to tighten the
terminal connector screws once the wires have been
inserted.
Power cables should be kept apart from
communication and other types of wiring to avoid
any ambient noise transmission to them.
If power cables must cross communication cables, do
so at a 90-degree angle.
The board connectors accept 22 AWG wires
(.65mm) per pole. Power cables should be 16-22
AWG, 18 AWG (1.02 mm diameter) recommended.
Keep all wires away from high speed data
transmission cables (for example, Ethernet, etc.).

View Wiring Recommendations
•
All wiring must comply with electrical wiring
diagrams as well as national and local electrical codes.
The power terminal is labeled TB1 on back of the View
touch screen. Strip power supply wiring (24 Vac) and
connect to the terminals marked L1 and L2 on the
supplied power connector. If an earth ground is necessary
(per local code), terminate to the ground terminal on the
power connector.
Figure 5. Power cable termination
NOTE:
When sharing power with other devices, a
consistent polarity for the AC wiring should be
maintained (L1 to L1, L2 to L2 and ground to
ground).

the View touch screen. Strip network wires and connect to
the appropriate terminals marked B+, A-, and GND on
the supplied connector.

Figure 6. Communication cable termination
MS/TP communication wiring is polarity sensitive.
Maintaining the polarity of the communication
wires (B+ to B+, A- to A-, GND to GND, and drain
wire to drain wire) must be done in order to
guarantee proper communication.
NOTE:
Jumper Configuration
The network bias resistors (pull up and pull down - J1 and
J3) increase the noise immunity of the network. This
configuration keeps the B+ and A- biased with a 200 mV
separation generating an idle condition at the receivers
and helps prevent false data on the network segment. The
network segment must be properly terminated to achieve
this effect. No more than two (2) network bias systems
can be active on a network segment at any given time
according to Clause 9 of the ASHRAE STD 135-2012.
Both J1 (pull up) and J3 (pull down) jumpers must be
installed when using biasing resistors.
The terminating resistor (TRM - J2) is installed at both
physical ends of the network segment. If the View is
installed as the first or last device on the network segment,
a separate terminating resistor is not necessary. Install the
J2 jumper to use the internal terminating resistor in the
View.

Installing the View in the Rough-In
Box
Removing the Faceplate
The View is shipped from the factory with the faceplate
installed on the mounting bracket. The faceplate must be
removed before the View can be installed in the rough-in
box. To remove the faceplate, grip the faceplate relief with
your finger on the right side of the unit and push in while
pulling towards you. The faceplate will lift off like a hinge,
simply pull the right side of the faceplate off the mounting
bracket and then pull the faceplate to the right. Then the
left side of the faceplate will be able to completely
removed.
IMPORTANT: When reinstalling the faceplate, push
down on the faceplate around the
perimiter to ensure that it is fully seated.
This ensures the outside gasket is in
place and seated properly.
