SETTING-UP SHELF BACKPLANE

The CT modem shelf backplane is configured in the factory. Use this procedure if the shelf

configuration has not been done or if the EEPROM has become corrupt.

Note: Sitespan should not be connected during this procedure

STEP PROCEDURE

1. LAT Settings

The following commands are entered using a terminal emulator and an RS232 cable to

the LAT (local access terminal) port on the front of the DA cards. The preferred

emulator is TERMINAL.EXE which came as part of the Windows 3.1 package. This is

a simple to use emulator, which has the advantage of being able to sent text files ‘one

line at a time’ and pause until a specified prompt is returned.

The terminal settings to connect to a LAT are:

Baud: 9600

Data: 8

Parity: None

Stop: 1 bit

Flow: None (not Xon / Xoff)

The terminal is also used to connect to the ST H8 LAT and the Trinity LAT. If

connecting to the Trinity, change the Baud rate to 19200, and put a ‘check’ in the box

labelled ‘inbound’ in the CR -> CR/LF section of the terminal preferences.

To send script files into the SC LAT, the settings of the ‘text transfers’ options should be

set to ‘line at a time’, and ‘wait for prompt string:’. The prompt string is Acc> for the

SC LAT, and ##FLASH## when sending new software to the ST.

2. Setting-up Shelf Backplane
