Restoring Communication with an Improperly Configured Unit

Configuring the unit improperly can 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 (Terminal) 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

for other

methods of resetting the unit.)

3. Tab to the desired prompt, and type y (Y

es) at one of the prompts.

If selecting . . . The following occurs . . .

Reset COM (Terminal) port

usage

H Port Use is set to Terminal so the

asynchronous terminal can be used.

H Data Rate (Kbps), Character Length, Stop Bits,

and Parity are reset to the factory defaults.

H Unit resets itself.

Reload Factory Defaults H All configuration and control settings are reset

to the Default Factory Configuration,

overwriting the current configuration.

H Unit resets itself.

CAUTION: This causes the current configuration

to be destroyed and a self-test to be performed.

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.
