3.2.1 Programming Configuration Switches 

There are 24 on/off configuration switches that control the operation of the NHRC-.  These are arranged 
into three groups of eight “switches”.  Seven of these switches are currently undefined and are reserved by NHRC 
for future expansion. 

Each switch can be set to a off (0) or on (1) state.  Each switch is addressed by its group number and switch number.  
The groups and switch numbers are all zero-based, that is to say the lowest numbered group is number zero and the 
lowest numbered switch is number zero.  This makes the valid group numbers 0, 1, and 2, and the valid switch 
numbers 0 through 7. 

3.2.1.1  Group 0 Switches –  Configuration 

Group 0 switches control configuration of the NHRC-. Note: In  group 0, only switch 7 has a function.  
The other switches should not be changed from their default configuration of zero.

tone telemetry mode 

1=send hi/lo tones instead of 
Morse code “ON” or “OFF” 

 

Switch 7 is used to change the on/off telemetry the sends from Morse code “ON” and “OFF” messages to 
two-tone sequences intended to notify the user of the state of the output.  When this switch is turned on (1), a port on 
command will receive acknowledgement of a low tone followed by a high tone, and a port off command will receive 
acknowledgement of a high tone followed by a low tone.  

Assuming the “program configuration command” has not been reprogrammed to something other than the factory 
default of “*0”, sending the following command will enable the “tone telemetry mode”: 

*0071
