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.
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.
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.
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.

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.
