Kramer RC-74DL: 12-Button Ethernet & KNET Control Keypad with Knob

The Kramer RC-74DL is a versatile 12-button control keypad engineered for modern AV environments. Featuring a tactile keypad, a precise rotary knob, and dual LCD displays, this device provides fast, context-aware control for complex room setups, boardrooms, lecture halls, and multi-room installations. Built to operate over Ethernet, the RC-74DL ties directly into Kramer’s Site-CTRL ecosystem and KNET network control, enabling remote management, monitoring, and orchestration across local networks or multiple sites. With its compact footprint and robust construction, it fits easily on a desk, mounts neatly in a rack, or hangs on a wall, delivering dependable performance under demanding usage. Operators, presenters, and technicians can rely on the RC-74DL to deliver consistent results, reduce training time, and streamline routine tasks in high-pressure environments.

• The RC-74DL provides 12 programmable buttons complemented by a responsive rotary knob, delivering fast, intuitive control for routing, display management, lighting, and system macros. Each button can be configured with macros, scenes, or direct device commands, enabling single-press execution of complex sequences and minimizing error during live events.
• Dual LCD displays offer real-time feedback for each control, showing current device states, targeted actions, and contextual prompts. This visual feedback helps operators verify outcomes at a glance, elevating confidence during critical presentations and ensuring that the right inputs and sequences are executed every time.
• Seamless Ethernet connectivity supports Site-CTRL and KNET protocols, enabling centralized control and monitoring across a network. This makes the RC-74DL an ideal part of a scalable Kramer control solution, allowing remote management, health checks, and synchronized operations across rooms or campuses.
• Rugged yet compact design enables flexible installation. The keypad can be placed on a desk for easy access, mounted in a rack for professional AV installations, or affixed to a wall for quick, convenient use in high-traffic environments. The integrated knob provides fine-grained input for volume, zoom, focus, or other parameters requiring smooth, incremental control.
• Future-proof, expandable control—designed to grow with your system. The RC-74DL integrates with Kramer’s evolving control software and devices, supporting updates, additional macros, and expanded sites. This makes it a smart long-term investment for organizations planning phased AV upgrades or campus-wide deployments.

How to install Kramer RC-74DL

Installing the RC-74DL begins with planning its network placement and operator workflow. Choose a location that offers comfortable reach for operators and clear visibility of the LCD displays. Connect the keypad to your local network using a standard Ethernet cable, ensuring the connection aligns with your Site-CTRL and KNET configurations. Apply power with the external supply and verify a stable power-on sequence, confirming that all indicators and displays initialize correctly. Once powered, use the Kramer control software or Site-CTRL interface to assign each of the 12 buttons to specific macros, scenes, or direct device commands; map the rotary knob to a frequently adjusted parameter such as master volume, camera zoom, or lighting level to enhance live control. Test the setup under real-world usage: execute standard room scenarios, switch between sources, adjust levels, and confirm that LCD prompts and status indicators reflect each action accurately. If integrating multiple rooms or a campus-wide system, replicate the configuration across additional RC-74DL units and link them through Site-CTRL or KNET groups to achieve unified, scalable control. Keep firmware up to date with Kramer releases to access new features, security improvements, and performance enhancements. For clean installations, consider cable management, proper ventilation, and secure mounting to prevent accidental disconnections during operation.
