7. CONFIGURATION VIA THE FRONT PANEL BUTTONS
7.1 INTRODUCTION
For users that prefer to configure the OM25 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 Amber. The Local Loop, Loop Back and Remote
LED indicators will display the parameter being configured.The Optical, Interface, Master and Test
LED indicators will display the parameter value. Sections 7.2.1 to 7.2.3 show the full lists of
parameters and their corresponding values that can be programmed.
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.
7.2 OPERATION
The "Local Loop" button is used to change the “Parameter Number”. The “Loop Back” button is
used to change the “Parameter Value”. Once programming is completed, the "Remote Loop"
button is pressed to store the new parameter value (this must be done within 30 seconds 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). The “Parameter Values” that can be selected are
displayed as a 4 bit binary number on the Optical, Interface, Master and Test indicators (Optical =
MSB).
