Restoring Communication with an Improperly Configured Unit

Improperly configuring the unit could render the menu-driven user interface
inaccessible. If this occurs, connectivity to the unit can be restored via a directly
connected asynchronous terminal.
Procedure
To reset COM port settings:
6-4
1. Configure the asynchronous terminal to operate at 19.2 Kbps, using a
character length of 8 bits, with one stop bit, and no parity. In addition, set Flow
Control to None.
2. Reset the unit, then hold the Enter key down until the System Paused screen
Resetting the Unit and Restoring Communication
appears. (See
for other methods of resetting the unit.)
3. Tab to the desired prompt, and type y (Yes) at one of the prompts.

Reset COM Port usage
Reload Factory Defaults
If no selection is made within 30 seconds, or if No (n) is entered, the unit
resets itself and no configuration changes are made.
Once the unit resets itself, connectivity is restored and the Main Menu screen
appears.
