Setting up Matrox device control
Matrox device control lets you control any device that supports the RS-422
SMPTE time code protocol when capturing or exporting material to tape in
Adobe Premiere Pro. To use this device control, you must connect your source
device or recorder as follows:
• Matrox MXO2, MXO2 Rack, and MXO2 LE Connect the RS-422
connector on your MXO2 hardware to the serial device control port on your
source device or recorder using an RS-422 serial cable (see
“MXO2 RS-422
serial connection” on page 18 , “MXO2 Rack RS-422 serial connection” on
page 27 , or “MXO2 LE RS-422 serial connection” on page 36 ).
• Matrox MXO2 Mini Matrox MXO2 Mini does not have an RS-422
connector. You can, however, use a suitable adapter to connect the serial
device control port on your source device or recorder to your computer. For a
list of supported device control adapters, see the Matrox MXO2 Support
section of our website at
