11000 Scanner Installation Manual
2.6 - Installation
2.4.2 Main serial interface
The signals relative to the following serial interface types are available on the
input/output connector of the scanner depending on the scanner model (see
section 1.3).
If the interface type is not compatible with the current communication
handshaking, then the system forces the XON/XOFF protocol.
The parameters relative to the interface selected (baud rate, data bits, etc.) can be
defined using the LDHOST utility program or "Host Mode" programming provided
on diskette.
Details regarding the connections and use of the interfaces are given in the next
sections.
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:
9-Pin 25-Pin Name Function
2 2 TX232 Transmitted Data
3 3 RX232 Received Data
6 4 RTS232 Request To Send
4 5 CTS232 Clear To Send
5 7 GND/SGND Signal Ground
