Enable Global Network Mode 

For networks with multiple base stations, remotes are ordinarily only able to 
link to one base station, set by the hopping pattern.  Mode 1 enables the 
global mode that allows remotes to link to any base station they can hear, 
acquiring whatever hop pattern is required. In this mode a remote can only 
change base stations once it is no longer registered with a base station.  

Set Hopping Pattern 

The HopNet has 64 preprogrammed hopping patterns (also referred to as 
network numbers).  By using different hopping patterns, nearby or co-located 
networks can avoid interfering with each other’s transmissions.  Even if both 
networks tried to use the same frequency, on the next hop they would be on 
different frequencies.   

Set Transmit Power 

The HopNet has two preset transmit power levels, 10mW (10dBm) and 
100mW (20dBm).  Control of the transmit power is provided through this 
command.  Default is 100mW. 

Read Receive Signal Strength Indicator (RSSI) 

This command reports the relative signal strength averaged over the last 10 
hops.  This command returns a one byte value that is proportional to received 
signal strength and can range from 

00H

 to 

FFH

.  Typical values range from 

30H

 to 

80H

 where the lower the number the lower the received signal 

strength and the higher the number the higher the received signal strength.  
This is a relative indication and does not directly correspond to a field strength 
number. This is available only at the remotes as the base station is the only 
source that transmits on a regular basis.  Plus, in a point-to-multipoint network 
the base will receive different signal strengths from each remote. 

Set Point-to-Point Direct Mode 

Sets point-to-point mode that is recommended for point-to-point applications, 
especially where the remote radio is mobile and may leave and re-enter the 
range of the base. This mode fixes the remote handle assignment to always 
be 30H and improves the re-registration process. Must be set in both base 
and remote radios.
