These read only commands return one of the three bytes of the unique factory-set 
serial number, which are also visible in the startup banner. 

Allows reduced power consumption by having a remote wake up only every 2

N

 hops 

to receive and transmit.  Power consumption is roughly proportional to the duty cycle 
selected.  For example, if N=2, the remote will wake up every fourth hop.  Power 
consumption will be roughly ¼ the consumption as when N=0.  This parameter must 
be set to the appropriate value when more than 16 remotes are in use. 

 When a remote is searching for a base to acquire and register with, it scans the 
frequency band very rapidly. This mode consumes about 80mA of current during this 
mode. To reduce the frequency consumption when a remote is in acquisition mode, a 
low power acquisition mode is provided. In this mode, the remote only scans the 
frequency band every other hop. This will reduce the average current consumption 
during acquisition to about 40mA. The tradeoff is it can take twice as long to acquire 
and register with a base, or up to 4 seconds.
