Lutron GRAFIK Eye

Lutron Grafik Eye

Connecting to a Grafik Eye system

All Grafik Eye interfaces are supported: GRX-RS232, GRX-CI-RS232, and GRX-CI-NWK-E. Connection to the RS232 interfaces can be done directly using a 3-wire RS232 cable, or via an Ethernet to RS232 interface.

If using an Ethernet to RS232 interface, set it up for 9600 bps, no parity, no flow control, 1 stop bit.

Connection parameters are TCP port and IP address in case of using a network interface.

The password is only needed if using a direct network connection to GRX-CI-NWK-E. The default password for this interface is ‘nwk’.

Important note: Make sure that you enable scene status feedback and raw feedback on the Lutron interfaces. This is done by setting the DIP switches 6 and 7 to ON on the interface itself.
