I presume RA2?
In RA2 under the programming tab create Phantom buttons in the main repeater.
Create an open/close button.
Set >>Select button type: Shade toggle
RS-232 protocol for Lutron
[Link: resi.lutron.com]RA2 starts on Pg28.
This is what a press/release phantom button #87 looks like in URC
ASCII. #DEVICE,1,87,3\x0D\x0A#DEVICE,1,87,4\x0D\x0A
Phantom buttons can be any button type!
