Kramer 6-Button Room Controller RC-76R

The Kramer RC-76R is a networkable control keypad designed to provide localized, tactile command input within a centralized audio-visual control system. Featuring six programmable buttons, each with an integrated multi-color LED indicator, this keypad offers a versatile and intuitive interface for end-users to trigger common AV functions in meeting rooms, classrooms, or presentation spaces. Its primary role is to act as a peripheral input device, converting simple button presses into complex control commands that are executed by a connected control processor, such as a Kramer Control system. The buttons can be labeled for specific actions like "Power On," "Source Select," "Volume Up/Down," or "Shades Down," providing a straightforward, user-friendly alternative to more complex touch panels or remote controls, thereby reducing support calls and enhancing the user experience.

A key feature of the RC-76R is its dual-network connectivity, supporting both standard Ethernet (for TCP/IP communication) and Kramer's proprietary KNET™ control network. This flexibility allows system integrators to choose the most efficient and reliable networking strategy for the installation. Using KNET™ can simplify wiring by allowing multiple Kramer control devices to be daisy-chained on a single low-voltage cable run, reducing switch port usage and cable clutter. When connected via Ethernet, the keypad becomes an IP device on the local network, capable of being addressed and managed directly by the control software. Each button is fully programmable, allowing a single press to send a string of commands, toggle between states, or activate macros that orchestrate multiple system actions simultaneously, such as lowering a projector screen, powering on a display, and switching to a specific video source.

The device is housed in a sleek, wall-mount enclosure designed for flush installation in a standard U.S. single-gang electrical back box, presenting a clean and professional appearance that blends with other wall switches and plates. Configuration is performed through Kramer's Control Suite software, where the buttons' functions, LED colors (for status feedback, e.g., red for off, green for on), and network parameters are defined. The RC-76R operates as a reliable, low-voltage peripheral, drawing power directly from the KNET™ bus or via Power over Ethernet (PoE), eliminating the need for a separate power supply. By offering a simple, robust, and flexible physical interface, this keypad extends the reach of a room's control system to convenient locations, such as near a doorway or lectern, providing essential, at-a-glance control that enhances the accessibility and reliability of the overall AV system.
