4.4 DMX wiring
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 P4 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 P4 in line (lighting control desk DMX-Out
-> P4 DMX-In). Connect the second P4 to the first in line, and so on (P4 no. 2 DMX-In -> P4
no. 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 P4 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.
WARNING: Never operate this fixture without lamp. Do not operate this fixture with-
out lamp cover!
