3.1 About HDBaseT™ Technology

HDBaseT™ is an advanced all-in-one connectivity technology (supported by the HDBaseT Alliance). It is particularly suitable in the consumer home environment as a digital home networking alternative where it enables you to replace numerous cables and connectors by a single LAN cable used to transmit, for example, uncompressed full high-definition video, audio, IR, as well as various control signals.

The products described in this user manual are HDBaseT certified.

3.2 About Power over Ethernet (PoE)

Power over Ethernet (HDBaseT) passes electrical power along with data on Ethernet cabling. This allows a single twisted pair cable to provide both a data connection and electrical power to compatible devices. PoE is convenient, flexible and safe requiring the use of fewer power outlets, simpler configuration and low power connections over standard category cables. A 48V DC power supply connects to the PoE transmitter and can power the PoE receiver up to a distance of 100 meters (330 feet). Beyond this range, a 12V DC power supply must be connected to the PoE receiver.

The TP-780TXR is a PoE injector. It cannot receive power from another PoE injector but only from a 48V DC power supply.

3.3 Using Twisted Pair Cable

For optimum range and performance, use the recommended Kramer cables available at www.kramerav.com/product/TP-780TXR.

We strongly recommend that you use shielded twisted pair cable.

Figure 3: Connecting the TP-780TXR/TP-780RXR Transmitter/Receiver Pair

4.1 Remote Control via an IR Transmitter

Since the IR signal on the TP-780TXR/TP-780RXR transmitter/receiver pair is bidirectional, you can use a remote control transmitter (that is used for controlling a peripheral device, for example, a DVD player) to send commands from either end of the transmitter/receiver system.

For more information on emitter/sensor extension cables, see the recommended Kramer cables available at www.kramerav.com/product/TP-780TXR.

The example in Figure 4 illustrates how to remotely control the DVD player that is connected to TP-780TXR using a remote control, via the TP-780RXR. In this example, the IR sensor cable is connected to the IR connector of the TP-780RXR and an IR emitter cable is connected between the TP-780TXR and the DVD player. The DVD remote control transmitter sends a command while pointing towards the cable-located IR sensor. The IR signal passes through the extension link and the IR emitter to the DVD player, which responds to the command sent.

4.2 Remote Control via RS-232

You can connect to the near-side of the extender system via an RS-232 connection to remotely control far-end connected equipment using, for example, a Kramer RC-43SL control keypad.

Note: A null-modem adapter/connection is not required.

To connect a RC-43SL via RS-232:

• Connect the RS-232 9-pin D-sub rear panel port on the transmitter or receiver system unit via a 9-wire straight cable.

• On the cable, the only pins that must be connected to the RS-232 port on the RS-43SL are:

• Pin 2 to pin 2

• Pin 3 to pin 3
• Pin 5 to pin 5

Figure 6: RS-232 Cabling Pinout

- Connect the RS-232 9-pin D-sub rear panel port on the other-side extender unit via a 9-wire straight cable to the RS-232 port on your projector.

Figure 7 shows bidirectional RS-232 control of the projector that is connected to TP-780RXR, via a RC-43SL connected to the TP-780TXR. The RC-43SL sends commands via RS-232 to control the projector.
