A data link is required for DMX controller operation, and for synchronized stand-
alone operation of multiple FiberSource CMY150s.
C a b l e a n d j u n c t i o n s
The FiberSource CMY150 provides a dual 1.8 meter (5.9 ft.) 24 AWG cable with
locking 3-pin male and female XLR connectors for data connection. The male cable
is the data input and the female cable is the data output. The connectors are wired
pin 1 to shield (gnd.), pin 2 to signal - (cold), and pin 3 to (hot).
Use RS-485 data cable designed for outdoor use to extend the link. RS-485 cable
has low capacitance and a characteristic impedance of 85 to 150 ohms. It is
electrically shielded and has at least 1 twisted-pair of conductors. The minimum
wire size is 0.2 mm
2
(24 AWG) for runs up to 300 meters (1000 ft.) and 0.322 mm
2
(26 AWG) for runs up 500 meters (1640 ft.).
When the fixture is installed outdoors, the XLR connectors
must be protected in a weatherproof housing. Alternatively,
data cables may be connected in weatherproof electrical
junction boxes, or the data cable can be replaced with
separate input and output cables that connect directly inside
the fixture. The leads connect to the main circuit board as
shown in the illustration to the right.
