In scenarios where your array of lights exceeds the capacity of a single daisy-chain configuration, yet you have yet to fully utilize your DMX universe, a valuable solution emerges: the DMX Splitter, also known as a DMX opto-split or DMX repeater. This device serves as an indispensable tool for efficiently managing your DMX feed and extending your control capabilities. 

The DMX Splitter is the sole method to divide your DMX signal into multiple lines. Each output on the splitter is capable of transmitting data to up to 32 devices, effectively broadening the scope of your lighting setup.

It's crucial to comprehend that employing a passive split, such as a y-cable arrangement, is not advisable. This approach leads to rapid signal degradation and subsequent operational issues. Instead, opt for a DMX Splitter to ensure optimal signal distribution and device performance.

When faced with a fixture featuring both 3-pin and 5-pin connectors, caution is advised. Connecting to both output connectors concurrently, creating a passive split, can induce problems. However, an effective workaround involves entering the fixture through either the 3-pin or 5-pin input and exiting through the alternate connector type. This strategy not only eliminates the need for excessive adapters but also preserves signal integrity.

In certain instances, compatibility challenges might emerge, particularly with more economical fixtures. Such fixtures might enter an automated mode upon signal loss, transmitting erratic data to downstream fixtures. This disruptive behavior can prove detrimental during a live show. Enter the DMX Splitter as a savior in such circumstances. By isolating these problematic fixtures onto dedicated lines, the splitter effectively averts disruptions caused by misbehaving devices, ensuring a seamless lighting presentation.

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 Storm10 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, D-Split and DIN-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.
