Ack/Nak; Scanner To Bioptic Communication; Scanner-Bioptic Packet Mode; Scanner-Bioptic Ack/Nak Mode - Honeywell Xenon 1910 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.
ACK/NAK On

Scanner to Bioptic Communication

The following settings are used to set up communication between Honeywell scanners and bioptic scanners.
Note: The scanner's baud rate must be set to 38400 and the RS232 timeout must be set to 3000 in order to communicate with
a bioptic scanner. See "RS232 Modifiers" on page 2-18, and

Scanner-Bioptic Packet Mode

Packet Mode On must be scanned to set the scanner's format so it is compatible with a bioptic scanner. Default = Packet
Mode Off.
* Packet Mode Off

Scanner-Bioptic ACK/NAK Mode

Bioptic ACK/NAK On must be scanned so the scanner will wait for an ACK or NAK from a bioptic scanner after each
packet is sent. The Scanner-Bioptic ACK/NAK Timeout (below) controls how long the scanner will wait for a response.
Default = Bioptic ACK/NAK Off.
* Bioptic ACK/NAK Off
