TP-780TXR/TP-780RXR - Overview
3 Overview
TP−780TXR and TP-780RXR are a high−performance, extended−reach HDBaseT
transmitter and receiver pair for HDMI (4K @60Hz 4:2:0), Ethernet, RS−232 and IR
signals over twisted pair. The TP−780TXR converts all input signals into an
HDBaseT signal that it transmits over twisted pair. The extended HDBaseT signal is
decoded by the receiver TP−780RXR, back to HDMI (4K @60Hz 4:2:0), Ethernet,
RS−232 and IR output signals. The TP-780TXR and the TP-780RXR can form a
transmission and reception system either together or each device separately with
another certified HDBaseT device.
The transmitter and receiver feature:
High Performance Standard Extender - High−quality professional extension
of max 4K@60Hz (4:2:0) 24bpp video resolution signal to maximum 100m
(330ft) extended−reach over CAT copper cable, and even further reach for
lower HD video resolution. Extender is standard, capable of being connected
to any market−available HDBaseT compliant extending products
HDMI Signal Transmission - HDMI 2.0 and HDCP 2.2 compliant signal,
supporting deep color, x.v.Color™, lip sync, HDMI uncompressed audio
channels, Dolby TrueHD, DTS−HD, CEC, Full HD, 2K, 4K, and 3D. EDID
and CEC signals are passed through from the source to the display.
Multi−channel Audio Transmission - Up to 32 channels of digital stereo
uncompressed signals for supporting surround sound at studio level.
Ethernet Transmission - Ethernet interface data flows in both directions to
allow extension of up to 100Mbps Ethernet connectivity for LAN
communication and device control.
Bidirectional RS−232 Transmission - Serial interface data flows in both
directions to allow data transmission and device control.
Bidirectional Infrared Transmission - IR interface data flows in both
directions to allow remote control of peripheral devices located at either end
of the extended line.
For optimum range and performance, use the recommended Kramer
cables available at www.kramerav.com/product/TP−780TXR.

Firmware Upgrade - Local transmitter upgrade via RS−232 control
connection and the K−Upload tool to ensure field−proven deployment.
LED Indicators - Status indicators for HDMI input and the HDBT output link
facilitate maintenance and troubleshooting.
Easy Installation - Single cable for transmitting HDBaseT signals and PoE to
the receiver. Compact Mega TOOLS™ fan−less enclosure for over−ceiling
mounting, or side−by−side mounting of 2 units in a 1U rack space with the
optional RK−T2B rack adapter.
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.

TP-780TXR/TP-780RXR - Connecting the TP-780TXR and TP-780RXR
4 Connecting the TP-780TXR and TP-780RXR
Always switch off the power to each device before connecting it to your
transmitter and receiver. After connecting your transmitter and
receiver, connect their power and then switch on the power to each
device.
You can use the TP-780TXR and TP-780RXR Extended Range HDMI Line
Transmitter/Receiver + POE to configure an HDMI transmitter/receiver system, as
shown in the example in Figure 3.
To connect the TP-780TXR, connect the:
1. HDMI source (for example, a DVD player) tothe HDMI IN connector.
2. RS-232 9-pin D-sub connector to a control device (for example, a Kramer
RC-43SL control keypad to control the projector).
3. IR 3.5mm mini jack to an IR emitter (for example, to control the DVD).
4. HDBT OUT RJ-45 connector over twisted pair to the HDBT IN connector.
Alternatively, you can use any other certified HDBaseT receiver device (for example,
the Kramer TP-590Rxr)
5. 48V DC power adapter to the power socket and connect the adapter to the
mains electricity (not shown in Figure 3).
To connect the TP-780RXR, connect the:
1. HDMI OUT connector to the HDMI acceptor (for example, a projector).
2. RS-232 9-pin D-sub connector to an RS-232 port (for example, a projector that is
controlled by the RC-43SL connected to TP-780TXR).
3. IR 3.5mm mini jack to an IR sensor (for example, to receive the IR remote
signal for controlling the remote DVD connected to TP-780TXR).
4. HDBT IN RJ-45 connector over Kramer HDBaseT cable to the TP-780TXR
HDBT OUT connector.
Alternatively, you can use any other certified HDBaseT transmitter device (for example,
the Kramer TP-590Txr)
5. If operating the TP-780RXR over a range of more than 100m (330ft),
connect the 12V DC power adapter to the power socket and connect the
adapter to the mains electricity (not shown in Figure 3).

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.

The example in Figure 5 illustrates how to remotely control the LCD display that is
connected to theTP-780RXR using a remote control transmitter, via theTP-780TXR.
In this example, the IR sensor cable is connected to the IR connector of the
TP-780TXR and an IR emitter cable is connected between the TP-780RXR and the
LCD display. The LCD display 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 LCD display, 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.
