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 RTS232 request to send
5 CTS232 clear to send
7 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).
