Net3 Four Port Gateway Setup Guide
DMX Basics & Pin-outs
The Net3 Four Port Gateway sends and receives DMX 512 control signal. The unit is can
contain a 5-pin XLR DMX input connector, a 5-pin XLR DMX output connector or a terminal
strip connector. DMX cables should be acceptable for DMX data transmission (not
microphone cable) and should follow the standard pinout. The optional secondary data pair
is not used by the Net3 Four Port Gateway.
The DMX network supports up to 32 devices connected to each DMX line. Termination is
required for all DMX networks and belongs at the beginning (source) of a DMX network and
with the last device physically connected device in the chain.
A compact switch (S1) located behind the DMX connector on each module is provided to
enable and disable DMX termination. These switches are defaulted to on for every module.
The most common reason to disable this termination is if you wanted to do a “touch and go”
connection on a terminal strip module. “Touch and go” means that you land DMX wiring on
the connector for the module, and continue to another DMX device.
