Hardware introduction


1. Interface function table

No. Name Function Remarks

① Power input Connect DC 3.8~5.5V power supply to supply power to the receiving card

② External interface Indicator and test button external interface

③ The network port is used to transmit network signals

Test button comes with a test program, which can realize four monochrome displays of red, green, blue, and white, and scan and display in horizontal sweeping, vertical sweeping, etc.

⑤ Power indicator The red light is always on, it means the power supply is normal. D1

Signal indicator flashes 1 time/sec. The receiving card is working normally and the network cable is connected normally. D2

Flashing 10 times/sec. The receiving card is working normally, and the cabinet is in the state of being calibrated.

Flashing 4 times/sec. In the loop backup state, the receiving card is working in the backup sending card state
