INTRODUCTION
For users that don't have access to a PC, or prefer to configure the OM100 without the need
of a PC, the operating parameters can be configured using the front panel controls.
Front panel programming is carried out by placing the unit into Programming Mode by
pressing the "Local Loop" and Loop Back" buttons simultaneously and then releasing them.
Programming mode will be indicated by the Status LED flashing Green. The remaining LED
indicators will display the first parameter number and it's on/off state.
Note: If the front panel controls have been previously set to "Loops only" or "Input disabled"
from the VT100 Front Panel configuration screen, it will not be possible to enter Programming
Mode.
OPERATION
The "Local Loop" and "Loop Back" buttons are used to programme the parameters. Once
programming is complete, the "Remote Loop" button is pressed to store the new parameter
value (this must be done within 30 second of the last programming action or the modem will
automatically leave programming mode and discard the new values). When "Remote Loop" is
pressed, the modem reboots into its new configuration.
All of the configurable parameters have a "Parameter Number" displayed as a 3-bit binary
number on the loop active indicators (Local Loop = MSB), and On/Off indication displayed on
the Test indicator
.
In the above example, parameter 1 is displayed, with the test LED On. It can be seen from the
following table, that parameter 1 is the master / slave setting, and that with Test LED On
indicates the unit is in Master Mode.
