DF1 Half-duplex Setup Parameters

When the module is powered up for the first time, the DF1 protocol
will be set to the default parameters. If these parameters are changed
and the setup is saved, then the module will always power up with
the new settings, unless the battery fails and power to the module’s
RAM is lost.

IMPORTANT

Choose [F] for full-duplex when using RSLinx
software.
