The gray Kramer 12-Button K-NET Auxiliary Control Panel is a 3 gang US wallplate remote controller for master room controllers such as the RC−74DL. It features 12 configurable front panel buttons, RGB backlit in three groups, and one configurable rotary up/down control knob with direction indicator LEDs.

Ideal for classrooms, boardrooms, and auditoriums, the 12−Button K-NET Auxiliary Control Panel can be used with a central control processor or connected to other control panels, interfaced via 2 K-NET connectors. A K-NET control channel provides power and control data to the wall plate controllers over a single cable. A USB port is available for firmware upgrades and setting the K-NET ID number.
