2.3.3 Auxiliary Interface - RS232

The auxiliary serial interface is used exclusively for RS232 point-to-point

connections. It is also used for configuring the DS2200.

The parameters relative to the auxiliary interface (baud rate, data bits, etc.) can be

defined using the WinHost utility program or "Host Mode Programming" installed from

the diskette.

The following pins of the 25-pin connector are used to connect the RS232 auxiliary

interface:
