Attention Matters

I. Cat.5e Twisted Pair Application Notes

568B：orange-white/orange/green-white/ blue/blue-white/green/brown-white/brown

568A：green-white/green/orange-white/blue/blue-white/orange/brown-white/brown

Equipment and Equipment Cable, [Cross]: One end is 568B, and One end is 568A.

Device and Switch Cable, [Crossover]: One end is 568B, and One end is 568A.

Equipment and Computer Cable, [Straight]: One end is 568B, and One end is 568A.

Note: Follow The Requirements, Do Not Define The Network Cable Sequence by Yourself.

II. Wire and Connecting Method From Lights to ControllerII.

1. If the Distance Between the Controller Output Port and the Lamp is Too far,
    it is Recommended to use 485 Special wire or Over Five or above Screen wire Connection.
    The best Connection is: Orange-A; Orange-white-B; Other GND (Ground).

2. A Terminal Resistance of 120R Shall be Added Between A and B at the End of Each Channel Signal.

3. Do not use Two Wires Wrapped Together at the Same Time, Such as Orange and Orange White, to A or B at the Same Time.

III. Key Application Point of The Controller Grounding

   MR-A28A Controller use a Metal Shell , the Rated Power Supply Voltage is AC100V-240V,
   so the Controller Equipment and the Metal Outer Box Must be Effectively Grounded .

   Because the Controller Signal Output Port Has the Exposed Metal Surface,
   The GND Signal Output Port Must be Effectively Grounded in Order to Ensure the Safe Application of the Operator Under the Safety Regulations.
