Pinouts of back panel connectors

The back panel has the following connectors:
• Two serial port connectors.
• A video input connector ("Video in"). If you have purchased Matrox Orion /Dual
for 4Sight-II, a second video input connector ("Video in 2") is present.
• Two digital video input connectors ("Digital Video in") (only if Matrox Meteor-II
/Digital for PC/104-Plus is purchased).
• The auxiliary I/O connector ("Aux. I/O").
• The Matrox opto-coupling module connector.
• An audio input (top) and an audio output (bottom) connector ("Audio").

Serial port connectors

The two serial port connectors are, more specifically, 9-pin, D-SUB male
connectors. Although they are both configured to the RS-232 standard, the
configuration of the bottom connector can be changed to accommodate the
RS-422/RS-485 standard. For a detailed description of how to do this, see the
BIOS reference appendix.
The pinouts for the serial ports are outlined in the following table:
