4.7.2 OPERATION LED INDICATIONS

The DS73 only utilizes the first and the fourth LEDs of the base unit module location during normal operation as

described below.

DS73 OPERATION DIAGNOSTIC LED DESCRIPTION

LED Description

1 Active Connection. This LED will remain illuminated for about 30 seconds after the last network connection is

terminated.

(flashing)

Cabling Error. This LED will flash continuously when a transmission attempt fails from a cable or a connection

malfunction. Once this condition is detected, the module will periodically attempt to transmit on the link and

this LED will flash as long as the transmission attempt fails. When the cable problem is corrected, this indication

will cease with no further intervention by the user. However, connections may have been lost and will need to be

checked and reconnected if necessary.

5 CONFIGURATION

Configuration changes for the DS73 peripheral communications module are made from the service port using the

following procedure:

1. If configuring from the service port, connect a terminal to the EIA-232 service port and configure the

terminal's serial parameters to 9600 baud rate, 8 word size, 1 stop bit, and no parity. Once the unit is powered

on, the following message will be sent out of the service port:

Bay Technical Associates

Service Port

Firmware Revision 4.15

This same message will be sent to the remote modem once a connection is established with the DS71-MD2

modem.

The DS71-MD2 modem has priority over the EIA-232 service port. When a connection is established

between a remote modem and the service port, the following message will be sent out of the EIA-232 service

port:

Incoming call

Service port access locked out

A terminal connected to the EIA-232 service port is not allowed access to the DS-Series unit while the

service modem has a connection with a remote modem. If a user connected to the EIA-232 service port is

currently communicating with the DS-Series unit and a remote user attempts to access configuration mode

through the service modem, the remote user is not allowed access to the DS-Series unit.

2. Place the desired module into command mode by sending $BTm<cr> or $BTm<lf> where m is the desired

module number (1 to 16) <cr> is Carriage Return and <lf> is Line Feed.

3. Access configuration mode by sending $CONFIG<cr>. No characters should be typed between $BTm<cr>

and $CONFIG<cr>.
