8-button 1-Gang Control Keypad, with 1 White DECORA® Design Frame

The Kramer RC-308/US-D(W/B) is a compact, eight-button control keypad designed for installation in a US standard 1-gang wall junction box. A single LAN cable carries both Power over Ethernet and communication, supporting a clean wall-mounted control point without separate power and communication cables. The keypad can operate as a user interface within a Kramer Control system or, through K-Config and its built-in I/O interfaces, as a flexible standalone room controller.

Ideal Use Cases

The RC-308 is suited to classrooms and meeting rooms where users need convenient access to multimedia equipment and other room functions. Its eight-button layout can provide a central interface for controlling complex multimedia systems, screens, lighting, and shades. The compact 1-gang format makes it appropriate for spaces where control needs to be accessible from the wall without introducing a larger control panel. Multiple keypads can also be used when a room requires control from more than one position.

Why Choose This Model

This US-D configuration combines eight-button room control with a familiar DECORA form factor. The included white and black DECORA design frames and faceplates allow the installed appearance to be coordinated with different room finishes. Its ability to work within Kramer Control makes it a focused user-interface option for an integrated control system. Built-in I/O interfaces, accessed using K-Config, also allow the keypad to serve as a standalone room controller when a separate central control arrangement is not required.

The single-cable deployment approach is another practical advantage. Power over Ethernet and communication travel through one LAN cable, reducing the number of connections needed at the keypad location. This supports straightforward placement in classrooms, conference spaces, and other rooms where wall-mounted controls must fit naturally into the surrounding design.

Installation and Integration

The RC-308/US-D is designed for a US standard 1-gang wall junction box. Its dimensions are 6.98 x 4.70 x 11.43 cm, or 2.75 x 1.85 x 4.50 inches, measured width, depth, and height. The US-D and DECORA configuration provides the frame and faceplate components specified for this model.

Network installation uses a single LAN cable for both PoE power and communication. For expanded control layouts, multiple keypads can be linked either side by side or at separate locations. A single K-NET cable carries power and communication between linked keypads, helping preserve a uniform design and user experience across the room. K-Config provides access to the keypad’s built-in I/O capabilities for standalone room-control applications.

Performance Highlights

• Eight physical buttons provide a dedicated room-control interface.
• Power over Ethernet and communication are carried over one LAN cable.
• Built-in I/O interfaces support use as a flexible standalone controller through K-Config.
• Integration with Kramer Control supports use as a system user-interface keypad.
• K-NET linking supports multiple keypads positioned together or at a distance.
• The compact enclosure fits a US standard 1-gang wall junction box.

What Makes It Different

The RC-308 combines three deployment options in one compact keypad: operation within a Kramer Control system, standalone room control through built-in I/O interfaces, and multi-keypad linking over K-NET. This makes the same eight-button interface suitable for a single control location or a coordinated group of wall stations. The included white and black DECORA design frames and faceplates further distinguish the RC-308/US-D(W/B) configuration by providing two supplied finish choices without changing the keypad itself.

Final Assessment

The RC-308/US-D(W/B) is a focused choice for wall-mounted control in classrooms and meeting rooms. Its eight-button interface, PoE deployment, Kramer Control compatibility, built-in I/O, and K-NET keypad linking address both integrated and standalone room-control requirements. The US 1-gang format and included white and black DECORA components complete a configuration designed for accessible control of multimedia systems, screens, lighting, and shades.
