Product description

The 124 is an economical bi-directional DMX512/RDM splitter. It is available with 3 pin (model 124-3)
or 5 pin (model 124-5) XLR connectors for all DMX512/RDM connections, as well as RJ45
connectors (model 124-RJ) and terminal block connectors (model 124-TB). These splitters have fully
isolated inputs. The four outputs are separately driven, but are not isolated from one another.

The rugged chassis made from 0.1” thick aluminum is designed for portable use. A ½” hole is

provided for truss or pipe mounting using a C-clamp or half coupler. Additional slots are provided for
safety cables.

The power supply is permanently attached so it can not be lost or separated from the splitter. It also
has auto-switching universal voltage input selection allowing the splitter can be used around the world
without changing any switches or jumpers.

Indicators are provided for power (red), and signal present (green).
