2.3.2 Serial Wiring

Serial communications are connected to the CPU board using removable screw terminal plugs on J6, J8 and J9 (Figure 2-5 on

page 9).

Use the following steps to connect the communications cable to the remote display.

1. Disconnect power and open the remote display by removing the captive screws on the front of the

enclosure and swing forward the hinged front cover.

2. Loosen the serial cable cord grip and push enough of the communications cable into the enclosure to allow

for attachment to the CPU board.

3. Strip 1/4" (0.65 cm) of insulation from the serial cable ends.

4. Make cable connections for RS-232, RS-422 or 20 mAcurrent loop communications as described in Table 2-2.

5. Remove excess cable from inside the enclosure. Tighten the serial cable cord grip.

2.3.3 RF interference

An EMI filter can be installed on the serial interface cable to eliminate RF interference (if necessary).

1. Run the serial wires through the EMI filter provided in the parts kit. See Table 2-3 on page 11.

2. Loop the serial wires around the EMI filter.

3. Use the provided plastic cable tie to secure the looped wires to the ferrite and the serial cable; this prevents

the ferrite from coming in contact with the CPU board.
