BASE UNIT AND MODULE OPERATION

107
The service modem can be set to an "echo" mode by sending five semicolons(;) in
succession from the host terminal. While in echo mode, the service modem will echo
back all characters received by the connected terminal. Echo mode is terminated by
selecting a specific M-Series module ($BTn<cr> n= 1-16) or a specific peripheral
communications port ($BTn,p<cr> n = 1 to 16 and p = 1 to 4.
BASE UNIT LED DESCRIPTION
All units are equipped with LEDs on the front panel. The green power LED indicates
power is applied to the unit. The red module LEDs are used to show connection
status. These LEDs are grouped into module numbers (Module 1, Module 2, ..., to
Module 16) with each module number having four LEDs (1 to 4). The functionality
of the LEDs for a particular module location depends on the type of module installed
in that location.
When a specific port on a V74, V75 or V87 module is selected by a host module, the
LED for the selected port and port 1 of the host module will illuminate. When a host
module places an I/O module into command mode, the LED for port 1 of the host will
illuminate. When a V74/V75/V87 I/O module is placed into configuration mode by a
host module, the service port, or the service modem, all LEDs for the I/O module will
illuminate. For example, if a host module selects port 1 of a V74 module, the LED for
port 1 of the host module and port 1 of the V74 module will illuminate.
There are two LEDs for the service modem (if installed) and a single LED for the
EIA-232 service port. An illuminated CX LED indicates the connected terminal has
selected the main board or an installed module. When a connection is established
between a remote modem and the service modem, the CD LED for the service
modem will illuminate.
