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
.
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 Baud Rate" on page 2-18, and
on page 2-21 for further information.
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.
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.
ACK/NAK On
* ACK/NAK Off
* Packet Mode Off
Packet Mode On
* Bioptic ACK/NAK Off
