3.3.3 Auxiliary RS232 Interface
The RS232 auxiliary interface is available for Point-to-Point connections. When it is
connected to the host computer it allows both transmission of code data and reader
configuration by VisiSet™.
Its communication parameters (baud rate, data bits, etc.) can be defined by the user.
For more details refer to the "Communication" folder in the VisiSet™ Help On Line.
The auxiliary interface is available on both D-sub connectors with the following pinouts:
9-Pin 25-Pin Name Function

Figure 25 - RS232 Auxiliary Interface Connections Using 9-pin Connector
When the auxiliary interface is permanently connected as part of the system cabling, it is
recommended to use the 25-pin connector and connect the cable shield as shown in Figure 24.
CAUTION
Avoid simultaneous connection to 25-pin and 9-pin signals of the auxiliary
RS232 interface.
CAUTION
When connected to a C-BOX 3x0/4x0, Matrix-1000™ can only
communicate through its Auxiliary Interface. The Matrix-1000™ 9-pin
Auxiliary port connector cannot be used for communication (i.e.
configuration through VisiSet™). To configure Matrix-1000™ through the
9-pin connector inside the C-BOX 3x0/4x0, the C-BOX 3x0/4x0 must first
be configured. See the relative C-BOX Installation Manual for details.
