COURIER HIGH SPEED MODEMS

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).
