3.14 Switch Configuration
Factory default configuration may be restored to the modem by setting the
DIL switch on the end plate to “Default” setting. This will not change the
configuration settings in non-volatile memory, but will set the volatile
configuration to factory default settings. This is equivalent to entering the
command “AT&F” to the modem. To restore Factory defaults, perform the
following
1. Set the switch to “Default” (down) position
2. Turn off module power
3. Turn module power back on
4. Return the switch to the up position
The module will now be configured for 19,200 baud communication on the RS232 DB9 port.
