Extension Port

The female 9-contact 0B ODU Extension port supports serial (RS-232 RX and TX), a General Purpose Input (GPI) trigger, General Purpose Output (GPO), Timecode, and Genlock. The connector also offers auxiliary 5-volt power out, with a maximum sustained current draw of 500 mA.

To operate the GPI contact closure style trigger, short Pin 6 (GPI) to Pin 9 (ground).

NOTE: The required mating connector is 9-Pin 0L Straight Plug Connector (ODU, part# SX0L0X-P09MCC0-0001).
