Appendix A 

 
Comp 2 or People Finder Protocol 

 
The system must be programmed with valid pager types or ranges. The system can be configured as 
Numeric, Alphanumeric or mixed. In the case of mixed systems the ranges must be defined at the time of 
ordering within the overall range 1 through 9,999. E.g. this could be ID 1 to 1000 reserved for numeric and 
1001 to 9,999 for Alphanumeric. Remember that the range selected must allow for Group Calls as well as 
individual pager ID’s. The reason for the range requirement is due to the change in the transmitted data 
word format under the POCSAG standard, coupled with the fact that the serial data provided by the host 
under this format does not allow the transcoder to differentiate between numeric and alphanumeric data 
formats.  
 
 
Example Numeric serial message string transmitted from the host to the transceiver:- 
 

 

 1234A<CR>1234567890U[-] 

<CR> 

 
The data starts with a one to four digit number followed by a beep type, (A,B,C or D) and then a ‘carriage 
return’ <CR>. This is then followed by the message (20 digits max) and another ‘carriage return’ <CR>. 
 
On sending a message to the unit in the correct format the transcoder will immediately recompose the 
string into the POCSAG format and transmit the same at the pre-programmed baud rate. The time taken 
to transmit the message is dependent upon the pager baud rate and the length of the message string.  
 
Example Alphanumeric serial message string:-   

  

 

1234A<CR> This is a message <CR> 

 
The sequence is exactly the same as for Numeric data except that the information transmitted can include 
the ISO 646 character set (full alphabet including both upper and lower case). 
 
Comp 2 can also provide message prioritization on certain Scope systems equipped with message 
buffering. This utilizes the A,B,C,D beep type to set the level of priority. Certain Scope products will also 
accept this format without the beep type included in the message string. This will invoke a default beep 
type being inserted by the transcoder. 
 

Comp 1 Protocol 
 

This is a simplistic interface which accepts a serial data string from the host and adds a single cap ID or 
address to the string enabling it to be transmitted to pagers globally. 
 
Example Alphanumeric serial message string:-   

  

 

This is a message <CR> 

 
On receiving a valid message string the transcoder will immediately add the pre-programmed ID and beep 
type, recompose it into the POCSAG format and transmit the same at the pre-programmed baud rate. The 
time taken to transmit the message is dependent upon the pager baud rate and the length of the message 
string.
