Multi-function Card Hardware Diagram
Interface descriptions
S/N | Name | Function | Remarks |
1 | Brightness sensor | Detect and automatically control the brightness, and the minimum brightness should be 15% of the full brightness. | Cables can be adopted to extend the distance between the sensor and the card. |
2 | Temperature sensor | It will sense the environmental real-time temperature, able to control the air-conditioning and fan switches, with the DS18B20 chip used. | |
3 | Power-in 1 | Connect 5V power supply to power the multi-function card. | Only one of the two should be used, it should have the function to protect against with the power reversal fault, and the voltage error shall be subject to ± 10%. |
4 | Power-in 2 | Connect 5V power supply to power the multi-function card. | |
5 | Net Port A | Connected to sending or net card | Regardless of input or output, the two net ports can be exchanged freely, able to support network cable upgrade. |
6 | Net Port B | Connected to receiving card | |
7 | Indicator Light | It indicates the status of power and signal transmission. | |
8 | Control power switch interfaces J9-J15 | Relay control, automatic power-on or off delay – Therein, J9-J12 indicate power-on and off delay linkage, and J13-J15 can control the switches individually controlled by the temperature (Attention to the relay current limit, please). | |
9 | Extended function interfaces J2-J7 | The voltage, humidity, sound and smoke detection can be extended, and if the function needs using, please consult our technical staff in advance. |
