TM8100/TM8200 Computer-Controlled Data Interface (CCDI) Protocol Manual

CCR

59

© Tait Electronics Limited

 

April 2007

Effect

An ACK response is sent back when a command has been accepted, the 
radio does not wait until the command has been executed. The ACK may 
be delayed, in some cases, but usually it is sent back immediately.

2.7

CCR Negative Acknowledgements

The radio validates the received strings since the last command on the serial 
port versus the CCR protocol when it sees an instance of the terminating 
character <CR>. It returns either a positive or negative acknowledgement. 
The negative acknowledgements are as follows.

2.7.1

Invalid CCR Command

If a string does not conform to the protocol, or there is something else 
inhibiting its execution, it is rejected and a negative acknowledgement is 
sent to the user. The negative acknowledgement has the following format.

Response

-ssrrxcc

Where:

Note

A command is only ever rejected with one error code.

Parameter

Value

+

ASCII ‘+’ character indicates that the command was accepted

ss

ASCII hex number ss is the size of the ack (always “01”)

x

echoes back the command identity, the first letter (R, T, A, B, S, M…)

cc

ASCII hex number cc is the checksum

Parameter

Value

-

ASCII ‘–’ character indicates that the command was rejected

ss

ASCII hex number ss is the number of characters for parameters

rr

indicates the reason for rejecting the command as follows:

■

‘02’ Checksum error

■

‘01’ Invalid command

■

‘03’ Parameter error in command

■

‘05’ Radio is busy

■

‘06’ Command is not accepted

x

echoes back the command identity, but only if the checksum in the 
command was correct

cc

ASCII hex number cc is the checksum
