When ACK/NACK is enabled, 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. Only after the ACK character is received by the 

 

OM-Gryphon™ does the reader respond with the good reception tone. 
 
If the reader does not receive an ACK or NACK, transmission is ended after the RX 
Timeout (see par. 5.1.4). See also Radio Protocol Timeout, par. 5.7.1 for Mx30 
Series readers. 
 
When ACK/NACK protocol is enabled, FIFO must be disabled manually, see par. 
5.1.3. 
 
 

 
GRYPHON™ Dx30 Readers 
This parameter determines whether data (barcodes) are buffered on a First In First 
Out basis allowing faster data collection in certain cases for example when using slow 
baud rates and/or hardware handshaking. 
 
If the FIFO buffering is enabled, codes are collected and sent out on the serial line in 
the order of acquisition. About 800 characters can be collected (buffer full), after 
which the reader signals an error and discards any further codes until the 
transmission is restored. 
 
If the FIFO buffering is disabled, each code must be transmitted before another one 
can be read. 
 
 
GRYPHON™ Mx30 Readers 
If enabled, the OM-Gryphon™ collects all messages sent by Gryphon™ Mx30 and 
sends them in order of acquisition to the connected Host. 
 
If disabled, Gryphon™ Mx30 blocks message transmission until the 

 

OM-Gryphon™ has completed transmission towards the Host.
