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 cross load. 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 +
The P7 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 xture.
Connect the DMX-out of the control desk to the rst P7 in line (lighting control desk DMX-Out
-> P7 DMX-In). Connect the second P7 to the rst in line, and so on (P7 no. 2 DMX-In -> P7
no. 1 DMX-Out). All 3-pin and 5-pin connectors are wired parallel. Do not use this xture 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 P7 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.

4.5 Rigging the fixture
WARNING: Keep xtures at least 0,5 meter away from high inammable material!
!
The P7 can either be placed on the oor or hang on a
trussing system in any position. When placing the unit
on the oor make sure that it stands on rigid ground,
because the air inlets in the base must not be covered
with anything! To mount the unit on a trussing system
use two of the original JB-Lighting omega brackets with
original Camloc-connectors. The Camlocs must snap in
to be locked properly. Ensure that the structure (truss) to
which you are attaching the xture is secure. If you install
the xture to a truss always attach a safety cable, that
can hold at least 10 times the weight of the xture.
