Introduction
The DMX splitters of the ISP-‐4 line of products boost an incoming DMX signal and provide it on four output ports.
This allows for connecting more than the 32 devices allowed according to ANSI E1.11 to a single universe, as well as
for building star topologies. Further more, the ISP-‐4 splitters also act as repeaters and may thus be used for
transporting a DMX signal across larger distances.
DMX signals often get disturbed by the environment or even by the devices connected to the signal. An ISP-‐4 splitter
may completely clear the disturbances if it’s connected at a location where the signal is still “readable”.
Providing four individually optically isolated outputs, as well as an optically isolated input, the ISP-‐4 splitters may
prevent harmful voltages applied to a given port from affecting the other ports and damaging the connected
equipment.
The ISP-‐4R variants work within DMX / RDM environments, as well as in pure DMX environments. Therefore, ISP-‐4R
splitters are a good solution not only for current RDM users but also for those who expect to use RDM in the future.
The ISP-‐4D variants on the other hand only work with DMX, while they ignore any RDM data.
ISP-‐4 splitters are Din rail mountable and powered by an external power supply unit (not included).
