Communications
RS-232/422 Host Port
Includes host port connections and host protocols.
Communications Options
You can communicate with the scanner through the following ports:
• 9-pin D-sub external connector
• Wiring box
• 25-pin D-sub external connector
Only one port can be used at a time to receive commands.
Communications with Host through the 9-pin Host Port
For the 9-pin configuration port, set the host communications settings as follows: 57.6K
baud, 8 data bits, 1 stop bits, and None parity. See Chapter 1, Quick Start , for more
information on using the 9-pin port.
Note: The 9-pin configuration port settings are not changeable.
Communications with Host through the 25-pin Port
The default 25-pin host port configuration settings are as follows: 9600 , 7 , 1 , and Even .
Making changes to these communications parameters without corresponding changes in
linked device(s) can result in the loss of menu access. If this should occur, connect via the
9-pin port and reset your scanner’s host parameters to match the 25-pin defaults.
Communications with Host through the Wiring Box
The settings are the same as those of the 25-pin port. See Chapter 14, Wiring Box , for
details on wiring connections.
