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 | 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. |
