Chauvet 3P user manual DM X Data Cable

Setup

cable please use data-grade cables that can carry a high quality signal and are less prone to electromagnetic interference.

DM X Data Cable

Use a Belden© 9841 or equivalent cable which meets the specifications for EIA RS-485 applications. Standard microphone cables cannot transmit DMX data reliably over long distances. The cable will have the following characteristics:

2-conductor twisted pair plus a shield

Maximum capacitance between conductors – 30 pF/ft. Maximum capacitance between conductor and shield – 55 pF/ft. Maximum resistance of 20Ω / 1000 ft.

Nominal impedance 100 - 140Ω

Cable Connectors

Cabling must have a male XLR connector on one end and a female XLR connector on the other end.

and interference, it is always

advisable to connect a DMX signal

CAUTION Do not allow contact between the common and the fixture’s chassis ground. Grounding the common can cause a ground loop and your fixture to perform erratically. Test cables with OHM meter to verify correct polarity and to make sure the pins are not grounded or shorted to the shield or each other.

3 - Pin to 5 - Pin Conversion Chart

Note!	If you use a controller with a 5 pin DMX output connector, you will need to use
	a 5 pin to 3 pin adapter. CHAUVET Model No: DMX5M.
	The chart below details a proper cable conversion:
