Data Distribution

DMX-512 is the industry standard protocol for theatrical control and has emerged for use in many architectural lighting applications for color and tunable white LEDs.  

Based on EIA-485 (differential signaling) it provides 512 channels of control (each with a value between 0 and 255). In a network these 512 channels represent one "universe" of DMX-512. A single controller (or master) controls multiple slave devices. For example, a lighting console controlling dimmers, LEDS, and moving lights or an architectural control such as Lehigh's impress DMX master stations, DTM6xx, and DTM-TS/MA.

RDM (remote device management) is an extension of DMX-512 adding support for bi-directional communications with slave devices for device information, control, and configuration.

DMX-512 is also available over an Ethernet network using industry standard protocols such as sACN and ArtNet providing multiple DMX-512 universes on a single CAT5/6 cable.

Lehigh offers solutions for distributing DMX-512 and supporting RDM with mergers, splitters, wireless DMX-512, and DMX-512 over Ethernet  multi-port nodes.

DMX Emergency Backup

In archtectural applications using DMX-based lighting for emergency circuits there will be a need to provide emergency control of those lights. Lehigh can provide a DMX emergency backup control which will force the DMX-based lights to 100% or a captured scene during the power outage until the normal power is returned. The H2816 DEBP (DMX Emergency Bypass Panel) provides this solution.
