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 | GND
| DC Return. This pin is the return path for the +VDC output. |
6 | VOUT | DC Output. This pin provides the regulated output from the DC/DC converter. |
