6 button Ethernet and KNET 1-gang Control Keypad, PoE

Ideal Use Cases

The Kramer RC-306/US-D(W/B) is a compact six-button control keypad designed for US standard 1-gang wall junction boxes. It provides a convenient user interface for controlling multimedia equipment and room facilities without placing a larger control device on a desk or lectern. The keypad is particularly suited to classrooms and meeting rooms where users need direct access to frequently used system functions.

• Classroom multimedia system control
• Meeting room equipment control
• Operation of screens, lighting, and shades
• User-interface duties within a Kramer Control system
• Standalone room control using its built-in I/O interfaces

Why Choose This Model

The RC-306 combines a six-button interface, Ethernet communication, Power over Ethernet, built-in I/O, and K-NET connectivity in a compact wall-mounted format. A single LAN cable carries both PoE power and communication, reducing the separate connections required at the keypad location. Its US-D-size faceplate configuration is supplied with both white and black DECORA design frames and faceplates, allowing the visible finish to be coordinated with the room.

This model can serve as a keypad within a Kramer Control installation or use its built-in I/O interfaces as a flexible standalone room controller. Configuration through K-Config makes the same compact device suitable for different control requirements without changing its six-button physical layout.

Installation and Integration

The US version measures 6.98 x 4.70 x 11.43 cm, or 2.75 x 1.85 x 4.50 inches, measured width, depth, and height. It is designed to fit a US standard 1-gang wall junction box, providing an installed control point that integrates directly into the room rather than occupying work-surface space.

Ethernet deployment uses one LAN cable for power through PoE and for communication. For expanded control layouts, multiple RC-306 keypads can be linked either side by side or at a distance. A single K-NET cable carries both power and communication between linked keypads, supporting a consistent physical design and user experience across multiple control locations. The source data does not specify the number or types of individual I/O connections, but identifies built-in I/O interfaces for standalone control applications.

Performance Highlights

The six-button arrangement gives end users a defined set of physical controls for complex multimedia systems and other room functions. The keypad can be integrated as the user-facing control surface in a Kramer Control system, while K-Config provides access to its built-in I/O capabilities for standalone applications. This dual role is useful when a project requires either centralized Kramer Control integration or a compact controller operating through local I/O.

PoE and communication over the same LAN cable simplify the connection path to the wall-mounted unit. K-NET offers a corresponding single-cable approach when multiple keypads need to operate together.

What Makes It Different

The RC-306 is not limited to acting only as a button panel. Its combination of Ethernet, PoE, built-in I/O, K-Config support, and K-NET keypad linking gives it two distinct deployment paths: an interface within a Kramer Control system or a flexible standalone room controller. Multiple units can be positioned together or separated around a room while retaining a uniform keypad design.

This RC-306/US-D(W/B) configuration is specifically packaged for US-D-size installations. It includes one white DECORA design frame and faceplate and one black DECORA design frame and faceplate, providing two supplied finish choices for the same keypad.

Final Assessment

The Kramer RC-306/US-D(W/B) is a focused room-control solution for installations requiring six physical buttons, US 1-gang mounting, Ethernet communication, and PoE. Its built-in I/O and K-Config compatibility extend it beyond basic keypad duties, while K-NET supports coordinated multi-keypad installations. For classrooms and meeting rooms controlling multimedia systems, screens, lighting, or shades, it provides a compact wall-mounted interface with both black and white DECORA finishing options included.
