Robust Master Control for Large-Scale AV 

Command expansive AV systems with the Kramer SL-280, a powerful 32-port controller operating over Ethernet, equipped with eight bidirectional RS-232, eight IR, eight GPI/O, and eight relay ports for precise management of scalers, displays, amplifiers, and environmental controls. The flexible, high-performance platform integrates with Kramer Control and API for customizable automation, supporting multiple gateways for remote I/O expansion. Perfect for small to large commercial, educational, and government installations, it delivers reliable, centralised control to optimise workflows and reduce setup complexity.

  • The SL−280 is a master/space controller (Kramer Control brain) that can operate over Ethernet with control interfaces that include: eight bidirectional RS−232, eight IR, eight GPI/O, and eight relays. It controls devices such as scalers, video displays, audio amplifiers, Blu−ray players, sensors, screens, shades, door locks, and lights. Multiple Kramer Ethernet control gateways can be used to add remote I/O ports.

    • Space Controller — Controls any AV device/display with its corresponding logic.

    • High Performance Architecture — Enables a scalable and flexible programming platform.

    • 8 RS–232 Bidirectional Control Ports — For controlling devices via bi–directional serial control protocols.

    • 8 IR Emitter & 1 IR Receiver Control Ports — Control devices via IR control protocols and learn commands from IR remotes.

    • 8 GPI/O Control Ports — Control devices via general purpose I/O ports, program configured as digital input, digital output or analog input interface for controlling sensors, door locks, audio volume and lighting control devices.

    • 8 Relay Control Ports — Control devices via relay contact closure, such as opening and closing drapes, shades, blinds, and projection screen scrolling.

    • Network Support — 10/100/1000Mbps Ethernet.

    • LED Indicators — I/O port state and system status.

    • Software Management Support — Kramer Control, API.

    • Controls small to large spaces for commercial, education and government sectors.
