Use AWG#20 to AWG#16 wires.
Remote controller wiring can be extended to a maximum
of 1640 ft.
(1) Strip the insulation to approximately 35/64" from the ends
of the wires that will be connected.
(2) Twist together the 2 wires and create a crimp connection
at the wire joint.
(3) If a special crimping tool is not used, or if the connection
is soldered, insulate the wires using insulation tape.
Group control using 2 remote controllers
It does not matter which of the 2 remote controllers you
set as the main controller. When using multiple remote
controllers (up to 2 can be used), one serves as the
main remote controller and the other as the sub-remote
controller.
