RS232 Interface

The serial interface is used in this case for point-to-point connections; it handles communication with the host computer and allows both transmission of code data and the programming of the scanner. This is the default setting.

The following pins are used for RS232 interface connection:

Pin

Name

Function

2

TX232

transmit data

3

RX232

receive data

4

SGND

signal ground

It is always advisable to use shielded cables. The overall maximum cable length must be less than 15 m (49.2 ft).
