PIN ASSIGNMENT
Pin | Name | Description |
1 | VA1 | RX Input (1). This input pin is used in conjunction with VA2 and connects to the centre tap of the transformer connected to pins 1 & 2 of the RJ45 connector (RX) - it is not polarity sensitive. |
2 | VA2 | TX Input (2). This input pin is used in conjunction with VA1 and connects to the centre tap of the transformer connected to pins 3 & 6 of the RJ45 connector (TX) - it is not polarity sensitive. |
3 | VB1 | Direct Input (1). This input pin is used in conjunction with VB2 and connects to pin 4 & 5 of the RJ45 connector - it is not polarity sensitive. |
4 | VB2 | Direct Input (2). This input pin is used in conjunction with VB1 and connects to pin 7 & 8 of the RJ45 connector - it is not polarity sensitive. |
5,6 | NC | No Connection |
7 | -VDC | DC Return. This pin is the return path for the +VDC output. |
8 | +VDC | DC Output. This pin provides the regulated output from the DC/DC converter. |
9,10 | NC | No Connection |
