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.
To achieve specified extension distances, use the recommended Kramer cables available at www.kramerav.com/product/KIT-400. Using third-party cables may cause damage!
Connect power
To power the devices:
- Set the PoC switches to ON on both devices.
- Connect the power adapter to one of the devices (KIT-500T or KIT-500R).
