Interface Baud Rate: This defines the baud rate used for communicating with the CL4790
over the serial interface. The RF baud rate is fixed at 76.8 Kbps and is independent of the
Interface Baud Rate. The default baud rate setting is 57600 bps unless the units have been
pre-configured by AeroComm. The Interface Baud Rate setting of the CL4790 must match
the Baud Rate setting of its host device.
Random Back Off: Random BackOff determines the random amount of time a transceiver
waits when a collision occurs before resending the packet again. The amount of randomness
is controlled by this parameter.
Channel Number: A number that designates an independent network of CL4790 units. Up
to 32 independent networks can be created. The valid range of values for this field is 16 to
47.
