OMX-RS232 Control Interface
Description
• Integrates GRAFIK 5000/6000/7000 Systems with
a touchscreen or other digital equipment that
supports RS232 communication.
• Provides RS232 monitoring commands that allow a
touchscreen to query GRAFIK Systems to:
– Determine which scene is selected.
– Keep track of buttons pressed.
• Provides RS232 control commands that allow a
touchscreen to operate GRAFIK Systems to:
– Select or sequence lighting scenes.
– Raise or Lower one or more zones.
– Lock lighting controls.
– Activate panic mode (lights go to full on).
• Functionality is setup via the GRAFIK System
Processor Panel.
• May be custom configured for other functions.

When Activated
If power goes out, locked zones stay
locked when power returns.
If power goes out, locked scenes stay
locked when power returns.
If power goes out, sequencing resumes
when power returns.
Sequencing loops through scenes 5 to 16.
DIP Switches 1-4 used to set address,
not function.
Interface reports Control Unit and
Wallstation button presses.
Interface reports scene changes.
When Otherwise
Power cycling unlocks locked
