GRX-PRG Programming Control Interface
Description
• Integrates a GRAFIK Eye Lighting Control System with a PC or
other digital equipment that supports RS232 communication.
• Provides a basic RS232 command set that allows a PC to
monitor and control lighting.
• Built-in Astronomic Timeclock provides ability to schedule
lighting events. Example: lobby lights turn on to scene 1 at
7:30 a.m. or 10 minutes after sunrise.
• Enables use of a PC to set up GRX-3500 and GRX-4500
Control Units.
• Comes with easy-to-use, “point-and-click” Windows
®-
compatible LIAISONTM software for scheduling the Astronomic
Timeclock and using the Programmer Interface.
• Functionality is selected using DIP switches.
• Operates with or without a PC connected.
• May be programmed to control any combination of
one to eight GRAFIK Eye 3000 or 4000 Series Control Units.
• GRX-3100 and GRX-4100 Control Units may utilize the
Astronomic Timeclock function of the GRX-PRG.
• GRX-3500 and GRX-4500 Control Units may utilize all
functions of the GRX-PRG.

Permits complete set up of the following on GRX-3500 or GRX-4500 Control Units via an
IBM
TM-compatible PC:
• Scenes, including light levels in 1% increments and fade times.
• Load type settings.
• Tamper-proof protection of scenes.
• Assignment of communication between Control Units and Wallstations.
• Dimmer Panel zone and load assignment
Allows an IBM-compatible PC to query GRX-3500 and GRX-4500 Control Units for their setup,
including type of Control Unit and number of zones.
LIAISONTM Software
• Allows use of a PC to create timeclock schedules for all GRX-3000 and GRX-4000 Control Units.
• Allows use of a PC to create setups for GRX-3500 and GRX-4500 Control Units.
• Provides downloading of schedules and setups to GRX-PRG Interface and Control Units.
• Works on any PC operating with Windows
® 3.1 or higher.
• Supplied by Lutron. Updates are available online at www
.lutron.com
System Communications and Capacity
• Low-voltage type Class 2 (PELV) wiring connects GRX-PRG Interface to Control Units and other
components.
• One GRX-PRG Interface per GRAFIK Eye 3000 or 4000 system. Automatically occupies
wallstation address 16.
• 50 feet (15m) maximum from GRX-PRG Interface to PC or other RS232 source.
Environment
32-104°F (0-40°C). Relative humidity less than 90% non-condensing.
