Serial Or Parallel Interface; Auxiliary I/Os On The Matrox 4Sight - Matrox 4Sight User Manual

40 Chapter 2: Connecting and configuring external peripherals to the unit

Serial or parallel interface

You can connect to the RS-232 serial interface using a 9-pin
RS-232 serial port cable.
You can connect to the Centronics parallel interface using a
25-pin parallel port cable.

Auxiliary I/Os on the Matrox 4Sight

Matrox 4Sight features 20 discrete LVTTL or TTL compatible
digital I/Os, with interrupt-generation capabilities on the
motherboard. Connect your device to these I/Os with a 25-pin
custom cable. For efficient use of these I/Os, assign an interrupt
line in the BIOS to the I/O pins. BIOS access is available by
pressing the Delete key during the boot process. Alternatively,
under Windows NT Embedded, you can assign an interrupt line
to the I/O pins using the Auxiliary I/O Settings option of the
NTConfig utility.
When accessing the Auxiliary I/O Settings dialog box with
NTConfig, two columns will be shown. The first (left) column
presents option buttons with their associated interrupt line
numbers. The second (right) column presents each line's
corresponding functional device. In addition, the right column
will reflect the status of each functional device by displaying
the 'ENABLE' or 'DISABLE' keyword in front of the functional
device item. It is important to note the device's status because,
when a specific interrupt line number has been selected with
the option button, the associated device has to be disabled to
leave the interrupt line free for the I/O pins. In certain
situations, you will have to make a compromise between the
interrupt line chosen and the functional devices needed by the
application.
