2.3.3Auxiliary RS232 Interface

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

The parameters relative to the aux interface (baud rate, data bits, etc.) as well as particular communication modes such as LOCAL ECHO can be defined using the WinHost utility program or "Host Mode Programming".

The following pins of the 15-pin connector are used to connect the RS232 auxiliary interface:
