Optional Configurations
Out-of-box, the XTend-NEMA RF Modem is configured to provide immediate wireless
links between devices. The modem's default configuration supports a wide range of
RF communications.
If the RF Modem must be configured to support specific needs of a data system,
many programming options are available. The RF modem recognizes an extensive
set of AT and binary commands. Several of the commands can be sent to the
modem using the DIP Switch that is located inside the weatherproof enclosure.

Restoring Modem Defaults
Other Configuration Options
Using the DIP Switch to configure the modem is one of several ways to configure
modem parameters. Other programming options are available such as using the
X-CTU Software "Terminal" and "Modem Configuration" tabs. Binary programming
is also supported.

restoring the modem
to its original default
parameter values.
Each time the RF modem is powered on, the modem is automatically configured
according to the positions of the DIP Switch. For example, the default positions
(switches 2 and 5 are ON (up)) cause the DT and MY parameters to be set to
specific values each time the RF modem is powered up.
To disable automatic configurations (so modified parameters persist in the modem
registry on subsequent power-ups), set swiches 5 and 6 to their ON (up) positions.
