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 communication modes such as LOCAL ECHO can be defined using the
VisoSetup utility program or "Host Mode Programming", installed from the CD-Rom.

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

Figure 9.1 RS232 auxiliary interface connections using hardware handshaking

The RTSAUX and CTSAUX signals control data transmission and synchronize the
connected devices. If the RTS/CTS handshaking protocol is enabled, the VB14
activates the RTSAUX output to indicate a message is to be transmitted. The
receiving unit activates the CTSAUX input to enable the transmission.
