GRYPHON™ Dx30/Mx30 

 
GRYPHON™ Dx30 Readers 
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. 
 
 
GRYPHON™ Mx30 Readers 
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. 
 
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. 
5.7.3. 
 
When ACK/NACK is disabled, there is no control from cradle to Host transmission, 
the reader responds with the good reception tone.
