Warning!
For protection from electric shock, the fixture must be grounded (earthed). The power supply
shall have overload and ground-fault protection.
RIGGING OR MOUNTING THE TANGO 250
Warning!
Attach an approved safety cable to the attachment point provided in the base. Never use the
carrying handles for secondary attachment. Always use an approved safety cable.

CONNECTING THE SERIAL DATA LINK

The Tango 250 has locking 3-pin data input and output sockets that are wired for use with DMX devices
with pin 1 to shield, pin 2 to cold(-) and pin 3 to hot(+).
1.
Connect the controller's output to the fixture's data input.
2.
Connect the output of the fixture closest to the controller to the input of the next fixture. If connecting
a fixture with pin 3 hot to a fixture with pin 3 cold, use a phase-reversing adaptor.
3.
To terminate the link, insert a male 120Ω XLR termination plug in the output of the last fixture.
TIPS FOR BUILDING A SERIAL LINK
Use shielded t
transmit DMX data reliably over long runs. For links up to 300 meters (1000 ft.) long, you can use
24 AWG, low capacitance, 85-150 ohm characteristic impedance, shielded cable with 1 or more
twisted pairs. For runs up to 500 meters (1640 ft.) use 22 AWG cable. Use an amplifier if the serial
link exceeds 500 meters.
Never use a "Y" connector to split the link. To split the serial link into branches use a splitter.
Do not overload the link. Up to 32 devices may be connected on a serial link.
Terminate the link by installing a termination plug in the output socket of the last fixture on the link.
The termination plug, which is simply a male XLR connector with a 120 ohm, 0.25 watt resistor
soldered between pins 2 and 3, "soaks up" the control signal so it does not reflect back down the
link and cause interferen
