Signal Termination from Computer to Display
The following communication options are available for the AF-6200/6300 series.
RS232
An RS232 network requires a 2-conductor shielded cable to transmit RS232 signal. Do not
subject this shielded cable to mechanical flexing after installation. This cable is not for
direct burial. Route RS232 cable in a dedicated, grounded metallic conduit at the base
of the display structure. This cable has a maximum length of 25' (7.62 m).
The signal cable terminates within the display in the J3 jack on the display controller.
RS422
An RS422 network requires a 6-conductor shielded cable to transmit RS422 signal. This
cable consists of unpaired wires that should not be subjected to mechanical flexing
after installation. This cable is not for direct burial. Route RS422 cable either in dedicated
metallic conduit or inside buildings; if not in conduit, keep away from interference signals.
With interference signals, a 2' (0.6 m) separation is typically required.
The signal cable terminates within the display to the terminal block labeled “IN RS422” on
the display controller. The opposite end terminates at the surge card.
Ethernet
An Ethernet network system requires a Cat-5 cable. Signal travels from the Local Area
Network (LAN) to the Ethernet In jack (J4) on the controller.
The signal cable terminates within the display at the controller. The opposite end
terminates at the control computer.
