Description
•IntegratesGRAFIK5000TM, GRAFIK 6000®, GRAFIK
7000TM, LCP128®, and Softswitch128® systems with
equipment that has a 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SystemsTM processor panel to set up
the OMX-IO interface for different modes, functions,
and momentary/maintained inputs and outputs.
Inputs/Outputs
•Providesfiveinputsandfiveoutputs.
•Providesbothnormallyopen(NO)andnormallyclosed
(NC)contacts.
•Usingtheinputs,contactclosuresinother
equipment can operate controls to:

Mounting
1. Mount the control interface directly on a wall, as
shown in the Mounting Diagram, using screws (not
included). When mounting, provide sufficient space
for connecting cables.
The unit can also be placed in the LUT-19AV-1U AV
rack using the screws provided with the unit. The
LUT-19AV-1U will hold up to four units.
If conduit is desired for wiring, the LUT-5x10-ENC
can be used to mount one unit.
2. Strip 4 in (10 mm) of insulation from wires. Each data
link terminal will accept up to two 18 AWG
(1.0 mm
2
) wires.
3. Connect wiring as shown in the Wiring Diagram
(next page). LED 1 lights continuously (Power) and
LED 7 blinks rapidly (Data Link RX) when the Class 2
(PELV) Data Link is installed correctly.
