Installing the RS-232 Circuit Card
1. Locate the RS-232 PCB connector on the iPort backplane circuit board (see
Figure 9a). The backplane circuit board is red,
and it is located at the rear of the iPort chassis utility box.
2. Carefully insert the RS-232 circuit card all the way into the RS-232 PCB connector (see
Figure 9b).
Note: The circuit card will only fit into the connector one way. Although the circuit card fits somewhat
loosely, when the iPort face is inserted into the utility box it holds the card in place.
iPort IW-22 Connections and Installation
See
Figure 10
, page 13
1. Before making connections, run a length of Cat5 cable through the wall from the iPort location to the balanced audio wall
plate location, and run a standard male-to-male RCA cable through the wall from the iPort location to the unbalanced video
wall plate location, as shown in
Figure 10, page 13. The balanced audio wall plate can be located up to 500 feet from the
iPort; the unbalanced video wall plate can be located up to 30 feet from the iPort.
• Find a location for the balanced audio wall plate that is near the audio system, control systems, and a source of AC power..
• Find a location for the unbalanced video wall plate that is near the local-zone video system.
2. Install RJ-45 connectors on both ends of the audio Cat5 cable as explained in the
Wiring Cat5/RJ-45 Cables section on
page 6.
