One composite video connector, one S-videoconnector, and one component video connector are available.Note:• Composite video output connectors are available when a compositesource is present.• S-video output connectors are available when an S-video source ispresent.• Component video output connectors are available when a compo-nent, composite or S-video source is present.8 IR IN CONNECTORAccepts input of IR signals from infrared distribution equipment.One 3.5mm jack that accepts a stereo plug (Tip/Ring connection)or mono plug (Tip/Sleeve connection) is available.9 RS-232 CONNECTORSThe RS-232 serial connector (1) is used to perform configuration down-loads and flash memory software upgrades. The RS-232 connector (2) iscapable of supporting future developments.10 TRIGGER OUTPUT CONNECTORSThe AV1 is equipped with one 5-pin DIN connector, which provides three12V DC outputs for controlling compatible components. The figurebelow shows how the connector is configured. The Power Trigger pin isnot user programmable, Trigger (1) is user programmable, Trigger (2) isan inverted sense from Trigger (1) and is not independently programma-ble. The Power Trigger is “on” when the AV1 is not in Standby and is “off”when the AVI is in Standby or powered down.
