Cat.5e twisted pair Application Notes

Controller and offline master controller and switch these three devices between each other using a crossover cable is better,One head is 568B, the other head is 568A. Above any equipment and computer room with a straight line,that is both 568B or 568A,Do not define the order of the straight line.

MR-318A Controller SD Card Application Notes

MR-318A memory card is used on the controller,need to use the FAT32 file system to format and then to store the corresponding offline files.

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 signal 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.

Controller connect to ground application notes

MR-318A 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.
