Dmx Wiring; Rigging The Fixture - JB-Lighting Varyscan P7 Bedienungsanleitung

P7

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 fixture.
Connect the DMX-out of the control desk to the first P7 in line (lighting control desk DMX-Out
-> P7 DMX-In). Connect the second P7 to the first 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 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 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 fixtures at least 0,5 meter away from high inflammable material!
The P7 can either be placed on the floor or hang on a
trussing system in any position. When placing the unit
on the floor 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 fixture is secure. If you install
the fixture to a truss always attach a safety cable, that
can hold at least 10 times the weight of the fixture.
