OMX-AV Control Interface
Description
• Integrates GRAFIK 5000/6000/7000 Systems with
equipment that has contact-closure I/O, including:
– Motion and occupant sensors.
– Timeclocks and push buttons.
– Motorized projection screens, skylights, window shades,
and movable walls.
– AV equipment.
– Security systems.
• Use the GRAFIK Systems Processor Panel to setup the
OMX-AV Interface for different modes, functions, and
momentary/maintained inputs and outputs.
Inputs/Outputs
• Provides five inputs and five outputs.
• Using the inputs, contact closures in other
equipment can operate controls to:
– Select scenes.
– Run sequences (loop through scenes).
– Lock lighting controls to prevent changes.
– Activate panic mode (lights go full on).
– Adjust control logic to reflect status of movable walls.
– Turn lights on or off based on room occupancy.
• Using the outputs, scene changes in lighting controls can:
– Trigger outputs to control other equipment.
– Provide status feedback to other equipment.

• Open circuit voltage: 36V maximum.
• Short circuit current: 4.0µA maximum.
Five Output Terminals
• Provide solid-state maintained or momentary (1-second) outputs.
• Outputs require an external relay and power supply (30VDC max., Class 2/PELV)
by others for contact closure devices.
• Maximum voltage: 38V
• Maximum current: 200mA
• Open collector (NPN) output: On-state saturation voltage 1.0V maximum,
off state leakage current 0.1µA maximum.
Status LEDs
Five Status LEDs light when associated output is active (on).
