I am replacing an old Crestron system with the MX-450 / MX-350 combo. The previous installer hardwired a remote that controls the shades to the Crestron system. I dug around and found a wireless remote he had stashed with a CAT 5 hardwired in to it. I unhooked the Cat-5 from the Crestron system and found that when I touch:

The Orange Pair Together: Shades Go Down
The Green Pair Together: Shades Stop
The Brown Pair Together: Shades Go Up

Is there a way to complete the circuit using the 450/350 so that I can control UP / DOWN / STOP from the remote? Thanks!
