Use a shielded twisted-pair cable with two pairs to connect the serial link. Connect all pins
if you want to upgrade the software in crossload. If a microphone cable (or any other cable
with only one pair) is used the software can not be updated via DMX line because pin 4
and 5 are not connected.
Pin assignment
Pin 1 = shield
Pin 2 = data -
Pin 3 = data +
Pin 4 = data out -
Pin 5 = data out +
shielded signal cable
The
A12 has 3pin and 5pin XLR connectors for DMX-in and DMX-out.
Do
not connect more than one data input and one data output on a fixture.
Connect
the DMX-out of the control desk to the first A12 in line. (lighting control desk DMX
-Out
/ A12 DMX-In). Connect the second A12 to the first in line, and so on (A12 2 DMX-In
/
A12 1 DMX-Out). All 3-pin and 5-pin connectors are wired parallel. Do not use this fixture
as
a DMX splitter!
The
DMX-Out of the last unit in line is not occupied unless problems occur. Then use a
termination
plug with the last A12 in line.(XLR-connector with a 120 Ohm resistor soldered
between
pin 2 and pin 3). Problems might occur when the line is overloaded, e.g.
