Some Facts About A DMX Splitter

By Alexandra Anderson


Often used in multiplying signals for several cables to use is the digital component referred to as DMX splitter. This particular type of device comes in many different forms. It can take the form of a rail, rack-mounted unit or that of a converter which links cables right into each other. The device is also used for duplicating and preserving digital signals for the expansion of standard networks.

The use of splitters will bring about control that is more centralized over several fixtures. This can be done with the use of programmable effects in theatrical lighting systems. It may also bring about an increase in networking possibilities. In addition, splitters will not only facilitate the division of signals, but they will also be boosting these through daisy chains and cable extensions.

The device is known to be able to extend network capacities by receiving inputs from daisy chains. Daisy chains are known to be linked trains of cables along with inline devices. After receiving input, the splitters will then become new output sources for the new chains. Daisy chains may branch out into their own when required. Multiple splitters may also be connected together.

There are many kinds of splitters out on the market these days. Designed as attachments into external structures are the rack and the truss types. These two can be attached with the use of safety wires, clips and velcro as well. The feature they have as attachments brings about a more versatile placement. In addition, it also makes them easier and faster to assemble.

Some types of splitters not only buffers but also protects signals with the use of both internal and external power supply. There are other types that use light-emitting diode or also commonly called LED indicators when trying to reveal details related to data and power. Mergers are known to have similar functions as splitters. One difference is that a merger combines signals into one rather splitting them into several lines.

For networks that are using multiple sources of power, signal transmission may be enhanced with the use of opto-isolator splitters. However, users need to exercise care when using these types as differences in ground voltages may bring about current crossovers and signal errors. Sometimes, this can even result to getting the equipment damaged.

DMX cables will be essential for the operation of these devices. However, there are several factors that users must consider prior to getting on buying the cables. Cables come in many different types and thus, considering which type best fits the component and its use will be essential for proper operation. Among the most common options are either the standard cables or the XLR cables.

The standard cable is known to facilitate data transition in a smoother way than the microphone XLR cable type. It can also make compensations for mixers that come with low output power. When choosing which to buy between these two, buyers should also consider the durability of the materials they have been made from.

Other characteristics essential to consider when it comes to choosing the best cables for a DMX splitter are inductance and capacitance. These two characteristics are actually possessed by all cables however, for sufficient performance, a characteristic impedance of 100 to 120 will be necessary. 120 is known to be the standard nominal rating for cables.
