Lutron Grak QS
Connecting to a Grak QS system
Connection to a Grak QS system is done via a QSE-CI-NWK-E interface, which allows for Ethernet and RS232 connect. For RS232
communications, set the same bit rate on the QSE-CI-NWK-E interface and on ML Gateway connection settings. Connection settings for Ethernet
are the IP address of the interface and the password. The default password is ‘nwk’.
Dening Grak QS resources
The resources you need to dene are control units and accessory controls (e.g. keypads) with which you need to interact. Each is dened by a serial
number which can be found on a label on each product, or from the control units bus status information, or by inspecting ML Gateway monitoring
information.
Grak QS events and commands
Events from a Grak QS system can be lighting scene changes on control units, or key presses.
Possible commands are scene changes on control units.
Lutron HomeWorks Interactive
Connecting to a HomeWorks processor
Connections to a HomeWorks processor can be done directly on Ethernet, RS232, or indirectly with a RS232 to Ethernet interface. This last option
is only relevant for older HomeWorks generations without network interface. For Ethernet connection, make sure that the HomeWorks project has a
‘telnet user’ dened with username, password, and all permissions granted.
! For RS232, hardware ow control is recommended. Be sure to use a fully wired RS232 cable in this case.
Dening HomeWorks resources
Resources on HomeWorks are keypads (both physical and phantom keypads). Keypads are identied by processor number, link number and keypad
address. Use the monitor tool to verify keypad addresses and button numbering.
Events and commands
- Events from HomeWorks include button activity and LED activity. Usually you should only use the keyboard button press. The other options are
provided for advanced use and need special care.
- Commands to HomeWorks are keypad button presses. This is general since all buttons on HomeWorks are completely programmable.
