DS4 DMX 512 1x4 TVS Splitter
PC Board - Now available in two versions:
A - TVS Isolated Input
B - TVS Isolated Outputs w/ True Fault
Indication
Version A (DS4-PCB-A) uses a
* SN75LBC184
IC on the input w/ TVS isolation
(*see notes below).
Version B (DS4-PCB-B) uses a
MAX3088 IC on the
input w/ True Fault Indication, and uses a
SN75LBC184
IC on each output offering TVS isolation on each output of
the splitter.
Description: The DS4 offers protection for your lighting board
or DMX generating device and
increases your
DMX 512 outputs. The DS4 is a DMX512 - 1 in
4 out splitter (or distributor, buffer, amplifier,
booster) that takes a DMX 512 output of a lighting
console or any device that transmits a DMX 512 signal
and offers protection with Transient Voltage
Suppression from devices on the
daisy chain such as higher voltage dimmers, and actively
splits the signal giving 4 separate DMX 512 outputs.
Field serviceable: socketed IC's for easy replacement, standard IC's available from many electronic parts suppliers, standard 5 x 20mm fuse. The input chip is also a high impedance chip. The standard chip SN75176A can be one of 32 chips on a daisy chain, with the *SN75LBC184 chip it could be one of 128 chips on a daisy chain.
*SN75LBC184 - [Version A] A terminated and open condition is considered an unstable state, the data/active indication LED could be either full on or full off. Data traffic is indicated by partially on or flickering illumination.
Also Note - [Verions A] the 4 outputs are separately driven and electronically isolated, not "Transient Voltage Suppressed" isolated from each other.
