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

The Controller Connect With Controller by Network With Cascades ,Recommended Purchase [Cross] Line Order: One is For 568B, The Other for 568A;

The Switch Connect With Controller by Network With Cascades, Recommended Purchase  [Cross] Line Order:One is for 568B, The Other for 568A;

Any of The Above Equipment Contact With Computer by Cascades, Recommended Purchase[Direct] line Order: The Both for 568B or 568A;

Note: Follow The Requirements, Do Not Define Your Own Network Line Order.

II. Wire and Connecting Method From Lights to Controller

1. Controller Output Port to the Lamp if The Distance is too Far，Recommended for
    The use of 485 Dedicated lines or Cat.5e Kind Shielded Cable Connection，The best Connection way is：  

    Orange-A；Orange White-B；Green-Addressing+（ADRI/PO+)；Green White-Addressing-（ADRI/PO-)；Other Connect to GND（Ground）

2. At the end of each road sSignal That is Between A and B to add a 120R Terminal Resistance.

3. Do Not Connect The Two Wires that are intertwined to Receive The Signal, Such as Orange and Orange White Connect to A+or B- at Same Time.

IIII. Controller Connect to Ground Application Notes

    MR-A28D Controller Using Metal case，Rated Supply Voltage is AC100V-240V，Therefore, it is Necessary to Ensure The Effective Grounding of The Controller Equipment and The Effective Grounding of The Metal Outer BOX。

    And the Output Port of The Controller is Exposed to the Metal contact surface，therefore, according to the requirements of safety regulations，to ensure safe use of the operator，signal output port GND signal must be effectively grounded.
