Mods, please remove this if inappropriate, but as what I'm selling is a bit unusual I wanted to attract a little more attention. I'm selling a GRX-PRG interface for controlling Lutron GrafikEye units over an RS232 connection to a PC. It's never been used, but was bought by me for a project which is no longer happening. The GRX-PRG does the following: 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. Current new cost of one of these is about £800, so getting a second hand one could be bargain way to add this functionality to an existing GrafikEye setup.
