2.3.2 Main Serial Interface
The signals relative to the following serial interface types are available on the
input/output connector:
RS232
RS485 FULL DUPLEX
RS485 HALF DUPLEX
An active 20-mA Current Loop interface is available if the optional INT-24 accessory
is installed. This accessory interface replaces the RS232/RS485 selections.
The main serial interface type and its relative parameters (baud rate, data bits,
etc.) are selected via software either using the WinHost utility program or Host
Mode programming. For more details refer to the section "Main Interface Menu"
in the WinHost Help On Line.
Details regarding the connections and use of the main interface selection are given in
the next paragraphs.
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 configuration of the scanner. This is the default interface.
The following pins of the 25-pin connector are used for RS232 interface connection:
Pin Name Function
2 TX232 transmitted data
3 RX232 received data
4 RTS232 request to send
5 CTS232 clear to send
7 SGND Main signal ground main interface
It is always advisable to use shielded cables. The overall maximum cable length
must be less than 15 m (49.2 ft).
