Ack/Nak; Scanner To Bioptic Communication; Scanner-Bioptic Packet Mode - Honeywell ORBIT 7120PLUS User Manual

ACK/NAK

After transmitting data, the scanner waits for an ACK character (hex 06) or a NAK
character (hex 15) response from the host. If ACK is received, the communications
cycle is completed and the scanner looks for more bar codes. If NAK is received, the
last set of bar code data is retransmitted and the scanner waits for ACK/NAK again.
Turn on the ACK/NAK protocol by scanning the ACK/NAK On bar code below. To
turn off the protocol, scan ACK/NAK Off. Default = ACK/NAK Off.
