Restoring Communication with an Improperly Configured Unit
Configuring the unit improperly 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:
1. Configure the asynchronous terminal to operate at 19.2 Kbps, using 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
appears. (See
Resetting the Unit and Restoring Communication
on page 8-3
for other methods of resetting the unit.)
3. Tab to the desired prompt, and type
y
(Yes) at one of the prompts.
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.
If selecting . . . The following occurs . . .
Reset COM Port usage Port Use is set to Terminal so the asynchronous
terminal can be used.
Data Rate (Kbps), Character Length, Stop Bits, and
Parity are reset to the factory defaults.
Unit resets itself.
Reload Factory Defaults
All configuration and control settings are reset to the
Default Factory Configuration, overwriting the
current configuration.
Unit resets itself.
CAUTION
: This causes the current configuration to be
