GRX-AV Control Interface
Description
• Integrates a GRAFIK Eye Lighting Control System
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.
• May be programmed to control any combination of
one to eight GRAFIK Eye 3000 or 4000 Series Control
Units.
Inputs/Outputs
• Provides five inputs and five outputs.
• Using the inputs, contact closures in other equipment
can operate Control Units to:
– Select scenes.
– Run sequences (loop through scenes).
– Lock Control Units.
– Activate panic mode (lights go full on).
– Adjust scenes to reflect status of movable walls.
– Turn lights on or off based on room occupancy.
• Using the outputs, scene changes in Control Units can:
– Trigger outputs to control other equipment.
– Provide status feedback to other equipment.

• Provides 5 inputs and 5 outputs. Outputs can control other manufacturers’ equipment.
Operating Modes
• Scene selection
• Special functions
Partitioning
• Occupant sensor
Five Input Terminals
• Accept maintained inputs and momentary inputs with 40msec minimum pulse times.
• Inputs must be dry contact closure or open collector (NPN).
• On-state saturation voltage must be less than 2.0VDC.
• Off-state leakage current must be less than 10µA.
• 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).
System Communications and Capacity
Low-voltage type Class 2 (PELV) wiring connects GRX-AV Interface to Control Units and
other components. Counts toward system maximum of 16 Wallstations/Control Interfaces.
Environment
32-104°F (0-40°C). Relative humidity less than 90% non-condensing.

• Operating mode can be selected by setting DIP
switches 5 through 8. Inputs and outputs may be
maintained or momentary as indicated.
• May be programmed to control any combination of
one to eight GRAFIK Eye 3000 or 4000 Series Control
Units.
• For scene selection and special function modes,
one Control Unit or a group of Control Units may
be assigned to be operated by the GRX-AV.
• With partitioning and occupant sensor modes, a
different Control Unit or group of Control Units
may be assigned for each I/O closure.
1
Scenes trigger the position of motorized window shades or projection screens.
2
Movable walls toggle Control Units between “in combination” and “independent” modes of operation. Each input is setup to
operate the Control Units associated with a movable wall (or walls).
• When a motorized wall opens, the wall’s switch contact closes. The Control Units now work “in combination.” Scene changes at
one Control Unit occur on all the associated Control Units.
• When a wall closes, the switch contact opens. The Control Units return to independent operation.
3
If an occupant sensor input provides momentary closure, use scene selection mode.
