5.9 DMX-512 connection/connection between fixtures
The fixture is equipped with both 3-pin and 5-pin XLR sockets for DMX input and output.The sockets are wired in parallel.
Only use a shielded twisted-pair cable designed for RS-5 and -pin or 5-pin XLR-plugs and connectors in order to
connect the controller with the fixture or one fixture with another.
Occupation of the XLR-connection:
DMX - output
DMX-input

XLR mounting-plugs (rear view):
If you are using the standard DMX controllers, you can connect the DMX output of the controller directly with the DMX
input of the first fixture in the DMX chain. If you wishhht to connect DMX controllers with other XLR outputs, you need to
use adapter-cables.
Building a serial DMX chain:
Connect the DMX output of the first fixture in the DMX chain with the DMX input of the next fixture. Always connect one
output with the input of the next fixture until all fixtures are connected.
Caution:
At the last fixture, the DMX cable has to be terminated with a terminator. Solder a 120
Ω
resistor between Signal
(–) and Signal (+) into a XLR plug and plug it in the DMX output of the last fixture.
5.10 Ethernet connection
The fixtures on a data link are connected to the Ethernet with Art-Net communication protocol. The controlling software
from PC (or lighting console) has to support Art-Net protocol.
Art-Net communication protocol is a 10 Base T Ethernet protocol based on the TCP/IP. Its purpose is to allow transfer of
large amounts of DMX 512 data over a wide area using standard network technology.
IP address
is the Internet protocol address. The IP uniquely identifies any node (fixture) on a network.
The Universe
is a single DMX 512 frame of 512 channels.
The ColorWash 2500E AT is equipped with -pin RJ- 5 socket for Ethernet input.Use a network cable category 5 (with
four „twisted” wire pairs) and standard RJ-45 plugs in order to connect the fixture to the network.

Patch cables that connect fixtures to the hubs or
LAN sockets are wired 1:1, that is, pins with the
same numbers are connected together:
1
- Shield

- Signal (-)

If only the fixture and the computer are to be inter
-
connected, no hubs or other active components are
needed. A cross-cable has to be used:
