4.2Understanding the Operating Parameters

Baud Rate, Parity and Data Bit:

These parameters set the scanner’s communication protocol which must be matched the same setting by the host. The default setting for the terminal interface is 9600 baud rate, none parity, and 8 data bit.

*Baud Rate can be 300, 600, 1200, 2400, 4800, 9600, 19200, or 38400 bps.

*Parity can be even, odd, space, mark, or none.

*Data Bit can be 7 or 8 bit long.

The scanner may not support settings with Data Bit as 7 and Parity as none combination. Such combination is treated as 7 data bits with MARK parity.

Data Direction:

This setting is only for the terminal wedge and corresponds to the terminal communication mode. If the terminal has:

*"Full Duplex" mode, set the data direction to "Send to Host".

*"Half Duplex" mode, set to "Send to Host and Terminal".

*"Block" mode, set to "Send to Terminal".
