2.4.2 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
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
