The DMX Splitter is a DMX512 1 in 4 out splitter that takes a DMX512 output of a lighting console or
any device that transmits a DMX512 signal and actively splits the signal providing 4 separate
DMX512 outputs, and offers electronic protection by separating the input device and output devices
using a Transient Voltage Suppression on the input from devices on the daisy chain network.

terminated and open condition is considered an unstable state, the yellow LED could be either full on
or full off. Data traffic is indicated by partially on or flickering illumination.
The standard chip SN75176A can be one of 32 chips on a daisy chain, with the *SN65LBC184 or SN75LBC184 IC,
it could be one of 128 chips on a daisy chain.
