[FAQ] Three FAQs for integrated RJ45 (Mag-Jack) application
The integrated network port (Mag-Jack) integrates the network transformer, common mode inductor, Bob Smith termination and indicator light inside the RJ45. Its pins include differential pins, center taps, NC, GND, LED and other different functions, and the connection methods are different. Most of the three types of problems, such as network port failure, indicator light not lighting, and EMC failure, are not damaged components, but incorrect pin wiring. VOOHU Electronics (VOOHU) explains these three types of common wiring errors in four parts: phenomenon, root cause, correct approach, and sel
