JB-Lighting Varyscan 3 Special 250MSD Bedienungsanleitung Seite 17

2.4 DMX wiring
Use a shielded twisted-pair cable to connect the serial link. For short distances a
microphone cable may be used.
Use 3-pin XLR connectors.
Pin assignment
Pin 1 = shield
Pin 2 = data - = blue
Pin 3 = data + = red
The pin assignment is the same for all Varyscans in line.
If the output socket of the control desks offers a 5 pin XLR female socket,
pin 4 and 5 are not occupied.
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). The DMX-Out of the last unit in line is not occupied unless
problems occure. Then use a termination 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.
2.5 Powering the fixture
Install a plug like described in 2.1.
Connected load: Voltage 230Volts, frequence 50Hz, power 740VA (3,2A)
Use a power supply of at least 920VA (4A) per unit, as the fixture need more
power during the process of powering up.
Connect the fixture to a propper installed grounded system only. If any doubts
on the electrical installations occur, consult a qualified electrician.
In case of damages occuring due to a not propper installed electrical system,
warranty claims will be invalidated.
Don´t use fixtures when top cover is not fixed propperly. Contact with electronical
parts can result in risk for life.
Connect fixture only after assuring that the electrical installation fits your demands
