3 Overview
The TP−780T and TP−780R are a 4K UHD, twisted pair receiver and transmitter for
HDMI, bidirectional RS−232 and IR signals. They support resolutions up to
4K@60Hz (4:2:0) UHD. The TP−780T converts HDMI, RS−232, and IR signals into
a twisted pair signal that it transmits to a TP−780R receiver. The TP−780R converts
the twisted pair signal back into HDMI, bidirectional RS−232 and IR signals. The
TP−780T and TP−780R support PoE (Power over HDBT). The TP-780T provides
power remotely over HDBT to the TP-780R 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-780T and the TP-780R can form a transmission and reception system
either together or each device separately with another certified HDBaseT device.
The TP-780T/R transmitter and receiver feature:
• A data transfer rate of up to 10.2Gbps (3.4Gbps per graphic channel)
• Resolution support of up to 4K @60Hz (4.2.0) UHD
• A range of up to 70m (230ft) at 2K, 40m (130ft) at 4K UHD resolutions.
For optimum range and performance using HDBaseT™, use
Kramer's BC−HDKat6a cable. Note that the transmissi on range
depends on the signal resolution, source and display used. The
distance using non−Kramer CAT 6 cable may not reach these
• HDBaseT™ technology
• Power over HDBT that 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.
4 TP-780T/R - Overview
• EDID pass through, passes EDID/HDCP signals from the source to the
display
• Bidirectional RS-232 & IR interface where commands and data can flow in
both directions via the RS−232 interface, allowing status requests and
remote control of the dest inati on unit (see Section 4.1)
• LED status indicators for input selection, output, 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 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-definiti on 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 (320 feet). Beyond this range, a 12V DC power supply must be
connected to the PoE receiver.
The TP-780T 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
Kramer engineers have developed special twisted pair cables to best match our
digital twisted pair products; the Kramer
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-780T/TP-780R transmitter/rec eiver 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 (to the AV
equipment) from either end of the transmitter /receiver system. To do so, you must
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 and 20 meter cable.
TP-780T/R - Connecting the TP-780T/R 11
The example in Figure 4 illustrates how to control the DVD player that is connected
to TP-780T using a remote control, via the TP-780R. In this example, t he external
IR sensor is connected to the IR connector of the TP-780R and an IR emitter is
connected between the TP-780T 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.

12 TP-780T/R - Connecting the TP-780T/R
The example in Figure 5 illustrates how to control the LCD display that is connected
to theTP-780R using a remote control, via theTP-780T. In this example, the
external IR sensor is connected to the IR connector of the TP-780T and an IR
emitter is connected between the TP-780R 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 -s ub 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.
