Scanner to Bioptic Communication
The following settings are used to set up communication between Honeywell scan-
ners 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
37, and RS232 Timeout on page 40 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.
