Radio I.D.

 All radios on the same network must have a unique address. If the radio is a 

“MASTER”, the address 

MUST

 be “0”. All other radios on that network must have an 

address between 1 and 254. 

Role

. The choices are “Master” or “Slave. There can be only one master per network. 

All others in that network must be slaves. 

Destination Radio I.D.

 Place the unique address of the radio to be communicated with 

in  this  field.  The  choices  are  0-254.  An  address  of  255  in  all  radios,  including  the 
master  will  cause  the  slaves  and  the  master  all  to  talk  to  each  other  in  broad  cast 
mode.  

Destination Network

 

I.D. 

This field must have the same ID as all radios on the same 

network. 

Encryption.

  Encryption  is  turned  on  by  default  and  it  is  important  to  note  that  the 

encryption code will be the same on all radios programmed from the same Radio Data 
Base, (Radio.rdb). Radios programmed from a different RDB will have different codes 
and  will  not talk  to  radios  that  were  programmed from  the first  RDB.  You must  either 
turn off encryption or manually generate a new code and program that code into each 
radio.  All  other  applicable  fields  are  selected  and  filled  in  automatically  when 
programming  is  done.  These  field  values  can  be  changed  but  only  advanced  users 
should consider changing the information in these fields. 

 

See the example in the figure below

.  

The 6 fields of special attention are numbered in red.
