JB-Lighting Varyscan P3 Operating Instructions Manual - 2.3 Rigging The Fixture
2.3 Rigging the fixture
The Varyscan P3 can either be placed on the floor or hang on a trussing system in a
vertical or horizontal way.
If mounting the unit to walls in a vertical way, the lamplife might be reduced. To mount
the unit on a trussing system use the original JB-lighting omega brackets with Camloc-
connectors. The Camlocs must snap in to be locked propperly. Always attach a safety
cable to secure the unit.

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 for pin 4 and 5 are not connected.

The pin assignment is the same for all Varyscans in line.
Connect the DMX-out of the control desk to the first Varyscan in line.
(lighting control desk DMX-Out / Varyscan DMX-In). Connect the second Varyscan
to the first in line, and so on (Varyscan 2 DMX-In / Varyscan 1 DMX-Out). All 3-pin
and 5-pin plugs are connected through, it is equal if you get in the 5-pin plug and
get out with the 3-pin plug or otherwise.
The DMX-Out of the last unit in line is not occupied unless problems occure. Then
use a termition plug with the last Varyscan in line.(XLR-connector with a 120 Ohm
resistor soldered between pin 2 and pin 3). Problems might occure when the line is
overloaded, e.g.
