PIN ASSIGNMENT

 

Pin #	Name	Description
1,2	NC	Do Not Connect.
3	VA1	Input (1). This input pin connects to the centre tap of the transformer connected   to pins 1&2 of the RJ45 connector. It is not polarity sensitive.
4	VA2	Input (2). This input pin connects to the centre tap of the transformerconnected to pins 3&6 of the RJ45 connector. It is not polarity sensitive.
5	VB1	Direct Input (1). This inputpin connects to pin 4&5 of the RJ45 connector(or centretap of 4&5). It is not polarity sensitive.
6	VB2	Direct Input (2). This input pin connects to pin 7&8 of the RJ45 connector(or centretap of 7&8). It is not polarity sensitive.
7,8	-VDC	Negative DC Output. This pin provides the -VDC output.
9,10	+VDC	Positive DC Output. This pin provides the +VDC output.

 

You are welcome to customize the POE modules of various sizes and appearances and function.
The layout is required to receive the initial research and development expenses.
After ordering a certain number of modules (usually 5000 pieces), the r&d cost can be deducted.
After the sample is qualified, batch production.
