M7-UC modem to assist in this case. This CONFIG button may be pressed at
any time, and forces the modem into a known operational state. The CONFIG
button is located inside the modem. Remove the rear cover, exposing the two
circuit boards. The button is in the center of the lower circuit board as shown
below.
The default settings 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)
3. Serial port on the front of the unit in RS232 mode, 9600bps, N/8/1.
If the unit was configured for RS-485, RS-422, or Ethernet, you must disconnect
other devices and use an RS-232 device to configure the M7-UC.
Even though the serial baud rate reverts to 9600 baud when the CONFIG button
is pressed and the IO port is RS232, it will revert back to the settings
programmed into the M7-UC modem once the Command Mode is exited.
5.6 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.
5.7 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.
