User's Manual

The default setting that the modem will revert to when the CONFIG button is

pressed are:

1. Serial port 9600 baud, 8 data bits 1 stop, no parity

2. ATCT setting set to 60000 (60 second time-out)

Even though the serial baud rate reverts to 9600 baud when the CONFIG

button is pressed, it will revert back to the ATBD setting programmed into the

modem once the Command Mode is exited.

6.6. Exiting the Command Mode

There are three ways to exit the command mode. They are:

1. ATSV Issuing the ATSV command saves the current configuration to non-

volatile memory, and then returns to the normal operation mode.

2. ATCN Issuing the ATCN command does not save the current

configuration, but it does cause the modem to continue to operate. If

changes to the configuration were done in the Command mode, these

changes will be used in operation, but they are not be saved to non-volatile

memory. The next time the modem is powered down and back up, the

modem will operate with the previously saved settings.

3. Time Out. After a pre-set amount of time (60 seconds is the factory

default time), the modem will automatically exit the Command Mode, and

continue normal operation. Changes will not automatically be saved. This

time-out duration may be set with the ATCT command.

6.7. Restoring Factory Defaults

The AT&F command may be used to restore the modem back to the factory-

default condition. Use this command with caution, as it will erase all

previously configured parameters. It will cause the modem to revert back to

the factory-defaults, as shown in the command table, “Factory Default”

column. The only parameters that it does not restore to default are the radio

type and radio calibration values R0-R9, and RA. This is so that the user

may restore defaults, and not have to re-calibrate the radio.

To erase ALL parameters, including the radio type and radio calibration, issue

the AT&F 123 command. There should not be any reason do this command,

because it will require the radio to be re-calibrated per the factory alignment

procedure.
