MR-A18A Controller Specification V1.2

Functions overview

I.System Characteristics:

1. 32-65536 degree Gray control, which can restore the real image color and detail;

2. Support Art-net protocol, based on Ethernet control protocol, realising lighting control.

3. Individually control the brightness per color : Red/Green/Blue, precisely adjust the white balance, more simple and more effective.

4. Precise gamma correction algorithm. It better conforms to the visual photographic characteristics of the human body, and the display color is more sufficient and rich, so as to perfectly reflect the animation or video effects of the designer.

5. Support 120-frame frequency at most, to guarantee demands for HD display and 3D display of the image.

6. Adopted Ethernet interface and UDP network protocol, to guarantee stable transmission, the maximum transmission distance is 100m.

7. The LCD display module timely display the controller parameters and status.

8. Controller output is compatible with dual model: TTL level signal and differential signal.

9. It can control many IC chips, you can change the IC model being controlled, clock frequency, duty ratio, gray scale and other parameters in software setting.

10. Dual network interface, can realize the controller cascade, the connection state can be automatically detected by controller and directly displayed by the software.

11. 8ports output, each port has no restriction on pixel load, which can be tested by clients according to IC chip characteristics.

12. Self-adapting 1000M /100M, or forced setting 100M, to guarantee the stability of large project.

II. Design Concept:

1. 1000 mega and 100 mega optional to adapt different project plans.

2. the system is two-way singnal redundancy, doubled the stability.

3. four colors has independent algorithm : energy saving and environmental friendly, pure colors.

4. Good applies to various kinds of fancy shape screens, multi-screen, building screens, led pixel screen, and other complex applications.

5. Added fiber optic conversion module, the control system supports optical fiber signal transmission.

6. Support signal transmission of wireless network and wireless bridge connection.

7. Support all the major LED driver chips in the market, such as MBI6020, MBI6021, MBI6024, MBI6030, LPD6803, LPD8806, LPD1886, TM1803, TM1804, TM1829, TM1812, TLS3001, TLS3008, MY9221, MY9231, WS2801, WS2811, SM16716, BS0815, BS0901, BS0902, UCS8903, UCS3903, TI5971, GW6201, GW6202, GW62052 and etc.

II. Definition of output interface

MR-A18A has 8pcs 5pin terminal interface for singal output.

5PIN terminal interface in order to sort from left to right, as shown below :

Remark: MR-A18A is compatible with TTL signal output and differential signal output.

IV. Basic Parameter

Controller install applications

1. Online mode (connected with computer )

MR-A18A Controller connect with the computer Ethernet port，as shown below：

2. Engineering case description and schematic diagram

For example, 96 × 18 dots matrix screen made by led point pixel light, use MR-A18A controller,

width 96 dot, height 18 dots, the wiring is arranged in vertical S type,

each output port control 3 lines led point light, totally need 32 SPI interfaces, as shown below:

Attention Points

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

It’s better to use a crossover cable between each other of these three devices: controller and offline master controller and switch, that is one end is 568B, the other end is 568A. must use a straight through line for any equipment above connect with computer, that is both ends 568B or 568A. Do not define the sequence of the straight line.

II. Wire and connecting method from lights to controller

1. If the distance from controller output port to the lamp is too far, recommend to use higher level shielded cable connection than Cat.5e, the best connection way is：

Orange-DATA; Green-CLK; Other connect to GND (Ground)

2. Do not use the two wires that are intertwined to receive the signal, such as orange and orange white connect to DATA at same time.

III. Controller connect to ground application points

MR-A18A Controller adopted metal case, rated voltage is AC100V-240V, therefore, you must ensure the controller device and it’s metal outer case are effectively grounded.

Plus there is exposed metal contact surface on the output interface of the controller, therefore, according to the requirements of safety regulations, to ensure safe use of the operator, the GND signal of output interface must be effectively grounded.
