Current vs. Voltage
The following table provides the luminaire’s current draw at specific voltages. Current is calculated
with the lamp on and all motors sequencing.
Data Cables
The luminaire is equipped with two, 5-pin XLR connectors for DATA IN and DATA THRU (out)
applications. DATA IN requires a 5-pin, female XLR connector and DATA THRU requires a 5-pin,
male XLR connector. When purchasing or constructing data cables, it is important that not only the
correct cable type be used, but also quality cable to ensure a reliable DMX512 system. Your cabling
should meet the following USITT DMX specification requirements:
•
Suitable for use with EIA485 (RS485) operation at 250k baud.
•
Characteristic impedance 85-150 ohms, nominally 120 ohms.
•
Low capacitance.
•
Two twisted pairs.
•
Foil and braid shielded.
•
24 AWG min. gauge for runs up to 1000 feet (300m).
•
22 AWG min. gauge for runs up to 1640 feet (500m).
Note:
Microphone type cables and other general purpose, two-core audio or signal cables are not
suitable for use with DMX512.
Refer to the USITT Recommended Practice for DMX512 guide for additional information regarding
DMX512 systems. How to obtain a copy is detailed in
“Additional Documentation” on page 1
