The SnakeSys B4 is a four universe DMX to Ethernet convertor. It supports four DMX512 ports that are configurable as either inputs or outputs and one DMX port that is always assigned as an input. The SnakeSys B4 is designed as a multi purpose box to be used in places where a small portable Ethernet to DMX conversion solution is required.

The SnakeSys B4 supports both Art-Net and ACN Streaming DMX network protocols. The DMX512 ports are fully configurable with DMX packet length, framing rate, and timings. In addition the SnakeSys B4 can operate in a non-network mode as a simple four port DMX buffer.

The SnakeSys B4 can be configured from the front panel using a 4-way DIP switch, and 2 rotary switches. In addition the interface can be set to ChamNet mode, where the SnakeSys B4 is configurable from the MagicQ console, avoiding the need for local configuration.

Multiple SnakeSys B4s can be used on a single network, either configured directly from the unit or by using ChamNet control from a MagicQ console. Multiple SnakeSys B4s can be synchronised together to ensure that the DMX output from the console is consistent and does not involve "tearing" either within universes or across multiple universes.
