Installing the RS-232C Interface, CI853/TP853

CI853 is powered from the processor unit via the CEX bus and requires therefore no

additional external power source.

Use the following procedure to install the CI853/TP853:

1. Mount the unit onto the DIN-rail, see Mounting AC 800M Units onto DIN-Rail

on page 71 and Installing the PM85x/PM86x/TP830 Processor Unit in Single

Configuration on page 84.

2. Connect the cable (maximum 15 m (16.4 yd)) to one of the contacts on the

baseplate. Connect the cable screen to the ground terminal within the connector

to ground the screen via CI583.

3. If cables longer than 15 m (16.4 yd.) are required, then a short distance modem

TC562 must be used. In this case mount the modem onto a DIN-rail in a

suitable position, connect a 24 V DC power supply to the modem and connect

cable TK853 from CI853 to the TC562 modem input terminals

4. Connect the TC562 modem output terminals to the outgoing cable.

The TC562 modem can be used for the following distances/speeds:

• Up to 1000 m (1100 yd) with transmission speed 19200 bit/s

• Up to 12000 m (13100 yd) with transmission speed 1200 bit/s

Connectors

Connect the RS-232C channels to the RJ45 connectors marked COM1 and COM2

on the TP853 Baseplate.
