1. Introducció
The Kramer TP-789R is a high-performance HDBaseT receiver designed for extending 4K60Hz (4:2:0) HDMI, RS-232, and IR signals over twisted pair cabling. This device supports bidirectional Power over Ethernet (PoE), allowing it to either supply power to a PoE acceptor device or receive power from a remote PoE provider. It extends video signals up to 40 meters (130 feet) for 4K@60Hz (4:2:0) resolution and up to 70 meters (230 feet) for 1080p HD video resolutions over Kramer copper cables. This manual provides essential information for the proper installation, operation, and maintenance of your TP-789R receiver.

5. Configuració i instal·lació
Follow these steps to properly set up your Kramer TP-789R receiver.
5.1 Diagrama de connexió
Figura 2: Typical Connection Diagram for Kramer TP-789R. This diagram illustrates the connection of a Blu-ray Player (HDMI source) to a Kramer WP-20 wall plate (HDBaseT transmitter) via HDMI and RS-232. The WP-20 then connects to the TP-789R receiver via HDBaseT (Cat cable), which also carries PoE. The TP-789R outputs HDMI to a display and RS-232 to a control device (SL-240C). An optional external power supply can be connected to the TP-789R.
5.2 Passos d'instal·lació
- Apagueu els dispositius: Ensure all devices, including the TP-789R, source, and display, are powered off before making any connections.
- Connect HDBaseT Cable: Connect a Cat cable (e.g., Cat 6a) from the HDBaseT output of a compatible transmitter (e.g., Kramer WP-20) to the HDBT IN port on the TP-789R. Ensure the cable length is within the specified limits (up to 40m for 4K, 70m for 1080p).
- Connecteu la sortida HDMI: Connecteu un cable HDMI des del SORTIDA HDMI port on the TP-789R to the HDMI input of your display device (e.g., TV, projector).
- Connect Control (Optional):
- For RS-232 control, connect your control system to the RS-232 bloc de terminals.
- For IR control, connect an IR emitter/receiver to the IR port.
- Connexió d'alimentació:
- If using PoE, ensure your HDBaseT transmitter or network switch is providing power and the POE LED is on.
- If using an external power adapter, ensure it is correctly connected and the power outlet is functional.
- Encès: Power on all connected devices. The LEDs on the TP-789R should illuminate to indicate proper connection and operation.
5.3 Configuració del commutador DIP
The SETUP DIP switches on the front panel are used for advanced configuration. Refer to the Kramer TP-789R product page or full user manual on the Kramer website for detailed information on DIP switch settings for EDID management, HDBaseT modes, and other functionalities.
6. Instruccions de funcionament
Once properly installed, the TP-789R operates largely automatically. Ensure your source device is outputting a compatible HDMI signal and your display is set to the correct input.
- Transmissió del senyal: The TP-789R will automatically detect the incoming HDBaseT signal and convert it to HDMI for your display.
- Indicadors LED: Monitor the front panel LEDs (IN, OUT, LINK, POE) to confirm active connections and power status. A solid LINK LED indicates a stable HDBaseT connection.
- Control de transmissió: RS-232 and IR signals are passed bidirectionally (if supported by the transmitter) allowing control of source or display devices from either end of the extension.
