DIP SWITCH SUMMARY
PURPOSE
The DIP switches, located at the rear of the modem, are for
adapting the modem to your equipment and personal require-
ments. If necessary, review your software documentation.
Some users are able to move a single switch with a finger tip. If
this doesn't work for you, use a toothpick or other small
instrument. Do not use a lead pencil.
OPERATIONS
The DIP switch settings are power-on defaults, read by the
Courier when it is turned on. If changed when the modem is
on, switches 1-7, and 9 require the ATZ (software reset)
command to initiate the new settings. If you've set switch 8
OFF to disable command recognition, and want to return the
modem to Smart mode so that it responds to commands, just
reset switch 8 to ON.
When you issue the ATZ command, the modem reads its DIP
switch settings and resets either to its defaults (DIP switch 10
OFF) or factory settings (DIP switch 10 ON).
