4 TP-780TXR/TP-780RXR - Overview
3 Overview
The TP-780TXR and TP-780RXR are a hi gh-perf orm ance, HDBaseT twisted pair
transmitter and receiver for 4K@60Hz (4:2:0) UHD, 2Kx4K HDMI, Ethernet,
bidirectional RS-232, IR signals and PoE. The TP-780TXR inputs HDMI, Ethernet,
RS-232, and IR signals and converts them into an HDBaseT twisted pair signal that
it transmits to a TP-780RXR receiver. The TP-780TXR provides power remotely
over HDBT to the TP-780RXR where it might be difficult to connect an external
power supply. This allows a single HDBT LAN cable to provide both data and
electrical power to compatible devices.
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:
• A bandwidth of up to 10.2Gbps (3.4Gbps per graphic channel)
• Maximum resolution of up to 4K @60Hz(4:2:0) UHD, 2Kx4K
• System range of up to 130m (430ft) at normal mode (2K), up to 100m at
normal mode (4K); up to 150m (490ft) ultra mode (1080p @60Hz @24bpp)
when using BC-HDKat6a cables.
For optimum range and performance using HDBaseT™, use
Kramer's BC-HDKat6a cable. Note that the transmission range
depends on the signal resolution, source and display used. The
distance using non-Kramer CAT 6 cable may not reach these ranges.
• HDBaseT™ technology
• Power over HDBT passes electrical power along with data on Ethernet
cabling. This allows a single cable to provide both data connection and
electrical power to compatible devices
• HDTV compatibility and HDCP compliance
• HDMI support for Deep Color, x.v.Color™, Lip Sync, HDMI Uncompressed
Audio Channels, Dolby TrueHD, DTS-HD, CEC.
• EDID pass through, passes EDID/HDCP signals from the source to the
Page 9
TP-780TXR/TP-780RXR - Overview 5
display
• Bidirectional RS-232 interface where commands and data can flow in both
directions via the RS-232 interface, allowing status requests and remote
control of the destination unit
• Bidirectional infrared interface for remote control of peri pheral devices (see
Section 4.1
)
• Ethernet pass-through
• LED status indicators for input selecti on, out put, link and power
• Compact MegaTOOLS® enclosures, and these can be rack mounted side-
by-side in a 1U rack space with the optional RK-T2B universal rack adapters
3.1 About HDBaseT™ Technology
HDBaseT™ is an advanced all-in-one connectivity technology (supported by the
HDBaseT Alliance). It is particularly sui t abl e 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-defi ni tion 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 electric al 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 (320 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 Ca ble
Kramer engineers have developed special twisted pair cables to best match our
digital twisted pair products; the Kramer BC-HDKat6a
(CAT 6 23 AWG cable)
significantly outperforms regular CAT 5 / CAT 6 cables.
We strongly recommend that you use shielded twisted pair cable.

4.1 Controlling AV Equipment 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 controlli ng a
peripheral device, for example, a DVD player) to send commands (to the AV
equipment) from either end of the transmitter /receiver system. To do so, you have
to use the Kramer external IR sensor on one end (P/N: 95-0104050) and the
Kramer IR emitter cable on the other end (P/N: C-A35/IRE-10)
Two IR Emitter Extension Cables are also available: a 15 meter cable and a 20 meter cable.

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

The example in Figure 5 illustrates how to control the LCD display that is connected
to theTP-780RXR using a remote control, via theTP-780TXR. In this example, the
external IR sensor is connected to the IR connector of the TP-780TXR and an I R
emitter is connected between the TP-780RXR and the LCD display. The LCD
display remote control sends a command while pointing towards the external IR
sensor. The IR signal passes through the TP cable and the IR emitter to the LCD
display, which responds to the command sent.

4.2 Connecting to a PC
You can connect to the transmitter/receiver system via an RS-232 connection
using, for example, a PC.
Note: A null-modem adapter/connection is not required.
To connect a PC via RS-232:
• Connect the RS-232 9-pin D-sub rear panel port on the transmitter/receiver
system unit via a 9-wire straight cable (only pin 2 to pin 2, pin 3 to pin 3, and
pin 5 to pin 5 need to be connected) to the RS-232 9-pin D-sub port on your
PC.
