Skaarhoj ETH-B4 Link

The SKAARHOJ ETH-B4 Link v2 is an Ethernet-to-B4 lens control interface that enables precise remote iris control for broadcast cameras using B4 mount lenses. It also integrates tally signaling and camera ID management, making it ideal for professional studio and live production environments.

The SKAARHOJ ETH-B4 Link v2 is a compact IP-based control interface designed to bring broadcast-grade B4 lens control into modern networked production workflows. It converts Ethernet commands into precise lens control signals, enabling remote iris adjustment for cameras equipped with B4 mount lenses. This makes it particularly useful in studio, OB van, and multi-camera broadcast environments where accurate exposure control is essential.

The unit features a Hirose 12-pin connector for direct integration with professional broadcast cameras and lenses. It includes a built-in camera selector dip switch for simple ID and IP configuration, allowing quick deployment in multi-camera setups. A dual-color tally system is also integrated, combining an LED indicator with relay output support for clear on-air and preview status signaling.

Designed for flexibility, the ETH-B4 Link v2 supports both Power over Ethernet (PoE IEEE 802.3af) and 12 V DC input power, allowing streamlined installation with minimal cabling. Its compact and lightweight design ensures easy mounting in tight production environments while maintaining reliable performance in demanding broadcast conditions.
