KPL-7 Scene Switch Installation Tips

The following tips can be time saving in the proper setup and operation of the RCS KPL-7 Seven Button Scene Switch. This article is for controllers with 2.15a or older firmware. KPL7 support is built into controllers with firmware 2.16 and higher.


  1. Wiring – the KPL-7 has a 4-terminal connection block and the terminal should be wired to the Leviton controller as follows:
  • 12V – connect to an Auxiliary 12V “+” terminal on the Leviton automation controller (NOTE: Do not connect to the Switched 12V “+”)
  • G – connect to any “GND” terminal on the Leviton controller.
  • B+ - connect to Pin 5 of the controller’s on-board serial port (NOTE:  “A” terminal when using a 10A17-1 Serial Interface Module).
  • A- connect to Pin 4 of the controller’s on-board serial port (NOTE: “B” terminal when using the 10A17-1 Serial Interface Module).
  1. KPL-7 Addressing – each KPL-7 requires a unique, which is based on the 4-position dip switch. NOTE: The addressing convention begins at “0”.
  2. RS-232 Jumper – the KPL-7 communicates via RS-485. When using an on-board serial port, the jumper below the port must be moved to the RS-485 position (middle and right pins).
  3. Serial Rate and Function – the Serial Rate should be set to 9600 Baud (default), and the Serial Function must be set to Pro-Link.  NOTE: Serial Port 1 can not be used - you must use Serial Ports 2-5.
  4. Controller Firmware – the controller firmware must be 2.16 or later, in order to have access to the “built-in” command set. If the controller does not have 2.16 or later firmware, the KPL-7 can still be used, but the commands will have to be named under Setup>>Names>>Messages. This can reduce the amount of control possibilities.
