(see www.kramerav.com/product/TP-789R).
Step 4: Connect the inputs and outputs
Always switch OFF the power on each device before connecting it to your TP-789R. For best results, we recommend that you
always use Kramer high-performance cables to connect AV equipment to TP-789R.
Connecting TP-789R as a power provider:
Connecting TP-789R as a power acceptor:

For the Ethernet connector, see the wiring diagram
below:
All DIP-switches are set to OFF (up) by default.
Changes to DIP-switch 4 only take effect after
rebooting the device.
For future use. Set to OFF (up).
OFF (up) – IR frequency is 38kHz.
ON (down) – Wide-range modulated IR frequency.
Set to OFF for backward compatibility
with 38kHz IR extension.
OFF – Normal operation mode.
ON – HDBT FW upgrade mode.
For optimum range and performance use the
recommended Kramer cables available at
www.kramerav.com/product/TP-789R.
When set to ON device operation is
disabled.
Step 5: Connect the power
When used as a PoE provider, connect the 48V DC power supply to TP-789R and plug it into the mains electricity (to also provide
power to a transmitter).
When accepting power from an HDBT transmitter via PoE there is no need to connect the 48V DC power supply.
