3.6 Signal Termination from Computer to Display

The 64mm, AF-3400 Mono display is designed for quicker signal and power
connection to the display and between displays.

• Signal will terminate to a watertight enclosure, which connects to the

primary display using a quick connect cable.

• Mounting the temperature sensor to the display structure and at least one

foot away from the display is preferred – terminate it to the primary display
with a quick connect cable (DO NOT mount the temperature sensor
between displays, or anywhere the airflow is restricted).

• If two primary displays are being used, signal and temperature sensor wires

will be connected between the controllers on each display.


A separate manual is provided for explaining the connection to the signal termination
enclosure. There are seven different methods of communication; your manual will
be one of these types:

3.7 Signal Termination between Displays

Reference Drawings:

Controller, Galaxy, 8 conn., J1087 .............................. Drawing B-177838

The connection between display controllers requires a 4-conductor shielded cable for
signal. One end will connect at the “RS422 OUT” 6-position controller board
terminal block (TB3) on the first primary display, and terminate on the “RS422 IN”
6-position controller board terminal block (TB2) on the second display. Refer to
Drawing B-177838 for terminal block locations. The interconnect signal wiring
between displays is shown in Figure 17.

A cable will also need to be routed for connection between displays for the
temperature sensor if one is being used. See Appendix B for the necessary wiring of
the temperature sensor.
