It’s advised to use a DMX Opto-splitter wherever possible to protect your DMX devices and infrastructure from unwanted electric noise or voltage spikes that could cause damage to your control hardware.

The DMX Output (RJ45) Ports on Storm 24 & 8 are not optically isolated from each other; if you have an unpredictable electrical environment, ENTTEC recommends pairing these with Opto-splitters or isolators.

The DMX USB Pro, Pro Mk2, Datagate Mk2, D-Split and RDS4 feature Opto isolation.

Ethernet devices are isolated by their very nature; Ethernet links are magnetically coupled, giving you 1000V isolation between the DMX line and Ethernet line.
