+ and Data
-). Please also
refer to your
DMX console manual to
select a correct
resistor.

7. Low Voltage Input:
Input power to the DC+ and DC- with Class 2 regulated (low
voltage) power source.
If attaching RGB
Flex Strip to
LT-840 DMX512, correct polarity
is imperative; Black
(or White) wire is positive (+) and goes
to “V+” terminal.
The common format
is to insert
the Red wire
to Ch1, Green
wire to Ch2
and
Blue wire to
Ch3. If unit
is set to
DMX Channel1, the
unit will automatically
occupy channels 1,2,3
and 4 on the master DMX
console. Ch4 is
for single color
LED Flex Strip.
If attaching a
single color, the
format is to
attach the positive
to COM and negative
to Ch1 (but can
also be Channel 2,3
or 4)
Warning: Input voltage must be identical to output voltage of
the LED Fixture!
WIRE 6-8 MM (0.25-0.30")
Exposed wire should not be more than 6- 8 mm long &
solder tip (tinned). Do not allow
Wires to cross and insure all exposed wire is fully inserted
into the screw terminals. Hand
tighten screw terminals. Use 22 to 14 AWG gauge wire for
output terminals.
Input Voltage must be identical to output voltage of the
LED
Input: For low voltage power input (12DC ~ 24VDC). V- and
V+. Use only 22 to 14 gauge
wire for input terminals.
