2.4.3 Auxiliary 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 operating modes such as LOCAL ECHO can be defined using the WinHost
utility program installed from the diskette or "Host Mode" programming provided on
diskette.
The following pins of the 25-pin connector are used to connect the RS232 auxiliary
interface:
Pin Name Function
20 RXAUX receive data
