Introduction
Welcome to Kramer Electronics! Since 1981, Kramer Electronics has been providing a world
of unique, creative, and affordable solutions to the vast range of problems that confront the
video, audio, presentation, and broadcasting professional on a daily basis. In recent years, we
have redesigned and upgraded most of our line, making the best even better!
Getting Started
We recommend that you:
•Unpack the equipment carefully and save the original box and packaging materials for
possible future shipment.
•Review the contents of this user manual.
Go to www.kramerav.com/downloads/TP-873XR or
www.kramerav.com/downloads/TP-874XR to check for up-to-date user manuals,
application programs, and to check if firmware upgrades are available (where appropriate).
Achieving the Best Performance
•Use only good quality connection cables (we recommend Kramer high-performance,
high-resolution cables) to avoid interference, deterioration in signal quality due to poor
matching, and elevated noise levels (often associated with low quality cables).
•Do not secure the cables in tight bundles or roll the slack into tight coils.
•Avoid interference from neighboring electrical appliances that may adversely influence
signal quality.
•Position your Kramer TP-873XR or TP-874XR away from moisture, excessive sunlight
and dust.

Connecting TP-873XR/TP-874XR
Always switch off the power to each device before connecting it to your TP-
873XR/TP-874XR. After connecting your TP-873XR/TP-874XR, connect its power and then
switch on the power to each device.
Figure 3: Connecting to the TP-873XR/TP-874XR Rear Panel
To connect the TP-873XR/TP-874XR as illustrated in the example in Figure 3:
1. On TP-873XR, connect an HDMI source (for example, a 4K Blu-ray player) to the
HDMI™ IN connector .
2. On TP-874XR, connect the HDMI™ OUT connector to an acceptor (for example, a
4K display).
3. Connect the TP-873XR DGKAT-2 OUT RJ-45 connector to the TP-874XR DGKAT-2
IN RJ-45 connector .
4. Connect IR extension:
▪On TP-873XR connect the IR 3.5mm mini jack to an IR emitter and connect it to
the Blu-ray IR sensor.
▪On TP-874XR connect the IR 3.5mm mini jack to an IR sensor.
Point the Blu-ray IR remote control transmitter to that IR sensor to send commands
to the Blu-ray player via DGKat 2.0.
5. Connect RS-232 extension:
▪On TP-873XR connect a controller (for example, SL-240C room controller) to the
RS-232 3-pin terminal block connector .
▪On TP-874XR connect the RS-232 3-pin terminal block connector to the display.

6. Connect the power adapter to the TP-873XR power connector and to the mains
electricity.
You can connect the power adapter to either the transmitter or the receiver since
DGKat 2.0 passes power bidirectionally.
This example shows the power adapter connected to TP-873XR but you can
connect the power adapter to the receiver instead.
Connecting to TP-873XR/TP-874XR via RS-232
You can connect to the TP-873XR/TP-874XR via an RS-232 connection using, for
example, a PC.
The TP-873XR/TP-874XR features an RS-232 3-pin terminal block connector allowing the
RS-232 to control the TP-873XR/TP-874XR.
Connect the RS-232 terminal block on the rear panel of the TP-873XR/TP-874XR to a
PC/controller, as follows:
From the RS-232 9-pin D-sub serial port connect:
•Pin 2 to the TX pin on the TP-873XR/TP-874XR
RS-232 terminal block
•Pin 3 to the RX pin on the TP-873XR/TP-874XR
RS-232 terminal block
•Pin 5 to the G pin on the TP-873XR/TP-874XR
RS-232 terminal block

Wiring the RJ-45 Connectors
This section defines the CAT cable pinout, using a straight pin-to-pin cable with RJ-45
connectors.
For DGKAT cables, ground shielding must be connected/soldered to the connector shield.
EIA /TIA 568B
We highly recommend using only Kramer
UNIKAT cables with these products. If using
3rd party shielded CAT-6A cables, both
ends of the shield must be soldered to the
connectors for the products to function
properly. Do not use any jumpers,
unshielded wall plates or mid-span cable
connections. These extenders are not
compatible with HDBaseT technologies.
Prior to signal extension, ensure that the
extension line cable is lying straight and not
coiled.
