Each unit will respond only to messages which contain a matching Unit
Number. Up to 99 unique unit numbers are available.  Any number of
units can be programmed with the same unit number.

The  Unit Number comprising of 2 digits is selected using the
configuration software.

Output monoshot (momentary) operation can be enabled by using the
configuration software. Each relay output can have its own monoshot
time, ranging from  0 to 10 seconds in 40mS steps. Setting the value to
0 disables the monoshot timer altogether, and the relay output is
latched until commanded off.

The 12-03-0000 has the  ability to remember the state of the relays
during a power down period. If this feature is turned on in the
configuration software, the relays will be returned to their previous state
at restoration of power.

The frequency of the radio channel can be set using the configuration
software. The nominal tuning range is approximately 455 to 465MHz,
but can be extended by factory tuning across the range 450 to 470MHz.
