Host Port Parameters
Important: This applies only to the 25-pin port and wiring box connections (not for 9-pin
port).
Note: See Communications with Host through the 9-pin Host Port on page 3-3 for 9-pin
host port parameters.
Baud Rate (Host Port)
Parity (Host Port)
Stop Bits (Host Port)
Data Bits (Host Port)
Usage:
Can be used to transfer data faster or to match host port settings.
Definition:
The rate at which the scanner and host transfer data back and forth.

Default:
9600
Options:
0 = 600 1 = 1200 2 = 2400

Usage:
Only changed if necessary to match host setting.
Definition:
An error detection routine in which one data bit in each character is set to 1
or 0 so that the total number of 1 bits in the data field is even or odd.
