Serial Wiring

Serial communications are connected to the CPU board using removable screw terminal plugs on J6, J8 and J9 (see
Figure 2-8).

To connect the communications cable to the remote display, do the following:

1. If the enclosure is not open, disconnect power and open the remote display by removing the captive screws

on the bottom of the enclosure and lower the mounting plate.

2. Open the captive retaining screws (Figure 2-6) and flip forward the hinged mounting plate.

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

attachment to the CPU board.

4. Strip 1/4" (.65 cm) of insulation from the serial cable ends.

5. Make cable connections for RS-232, RS-485, or 20 mA current loop communications as described in

Table 2-2.

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

If you are experiencing RF Interference, follow the instructions below.

1. Loop the serial wires through the cylindrical ferrite (PN 66730) provided with this manual. See Figure 2-7

below.

2. Using the plastic cable ties provided, secure the wires to the ferrite and the serial cable to the learn switch

wires to keep ferrite from contacting the CPU board. See Figure 2-7 below.
