This parameter sets a transmission protocol in which the Host responds to the reader 
after every code transmitted. The Host sends an ACK character (06 HEX) in the case 
of good reception or the NACK character (15 HEX) requesting re-transmission, in the 
case of bad reception. 
 

 

ACK or NACK

data 

 

 
If the reader does not receive an ACK or NACK, transmission is ended after the 
RX Timeout (see par. 5.1.4). 
 
When ACK/NACK protocol is enabled, FIFO must be disabled manually, see par. 
5.1.3.

The transmission protocol takes place between reader, cradle and Host. The reader 
passes its data (code read) to the cradle, which sends it to the Host. The 
management of responses (from Host or cradle) depends on the Transmission Mode 
parameter, see par. 5.9.4. 
 
In the following descriptions the completed transmission is indicated by the Beeper 
Control for Radio Response parameter with its default setting to Normal, see par. 
5.9.5. 
 
When ACK/NACK is disabled (in One-Way tx mode), there is no control from cradle 
to Host transmission, the reader responds with the good reception tone.
