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
