Wiring the RJ-45 Connectors
This section defines the TP pinout, using a straight pin-to-pin cable with RJ-45 connectors.

For HDBT cables, it is recommended that the cable ground shielding be connected/soldered to the connector shield.

EIA /TIA 568B

To achieve specified extension distances, use the recommended Kramer cables available at www.kramerav.com/product/VP- 427X1.Using third-party cables may cause damage!

Step 5: Connect power
If there is no PoE via the HDBT input, connect the power adapter to the VP- 427X1 and plug it to the mains electricity.
