Installation
Installing the HDMI Transmitter/Receiver
Note: Make sure that the HDMI Transmitter and Receiver are each located near an AC Electrical Outlet and that all devices connected to them are turned off.
- Setup the Local Video Source (e.g. computer) and the Remote Display (place/mount the display appropriately).
- Position the HDMI Transmitter near the Video Source you set up in step 1.
- On the back of the HDMI Transmitter, connect an HDMI cable from the Video Source (e.g. computer) and to the HDMI IN port.
- Position the HDMI Receiver near the Video Display you set up in step 1.
- On the back of the HDMI Transmitter, connect an RJ45 terminated CAT5e/CAT6 Ethernet cable (cables sold separately) to the RJ45 connector.
- Connect the other end of the CAT5e/CAT6 Ethernet cable to the RJ45 connector on the back of the HDMI Receiver..
Notes: Properly grounding the HDBase Transmitter and HDBaseT Receiver can prevent damage and improve audio/video signal quality.
The cabling should not go through any networking equipment (e.g. router, switch, etc). - On the back of the HDMI Receiver, connect an HDMI cable from the Video Sink
Device into the HDMI Out port. - Connect the Universal Power Adapter to the DC 18V Power Port on either the HDMI Transmitter or HDMI Receiver and to an AC Electrical Outlet to power both the HDMI Transmitter and HDMI Receiver (using the Power Over Cable feature).
(Optional) Installing the Ground Wires.
Note: Grounding is recommended in environments with high levels of electromagnetic interference (EMI), or frequent electrical surges.
Transmitter/Receiver (Back)
- Using a Phillips head screwdriver (sold separately) remove the Grounding Bolt.
- Attach the Grounding Wire to the shaft of the Grounding Bolt.
- Insert the Grounding Bolt back into the Ground.
- Tighten the Grounding Bolt, making sure not to over-tighten.
- Attach the other end of the Grounding Wire (not connected to the HDMI Transmitter/HDMI Receiver) to a proper earth ground connection.
Installing the IR Receiver and IR Blaster
The IR Receiver and IR Blaster can be connected to either the HDMI Transmitter or HDMI Receiver.
HDMI Transmitter
If the device receiving the IR signal is at the remote side:
- Connect the IR Receiver to the IR In Port on the front of the HDMI Transmitter
- Position the IR Sensor where you’ll point your IR Remote Control. If the device receiving the IR signal is at the local side:
- Connect the IR Blaster to the IR Out port on the front of the HDMI Transmitter.
- Position the IR Sensor directly in front of the video source’s IR Sensor (if you’re unsure, check the manual of your video source to determine the IR sensor location).
HDMI Receiver
If the device receiving the IR signal is at the remote side:
- Connect the IR Blaster to the IR Out Port on the HDMI Receiver.
- Position the IR Sensor directly in front of the device’s IR Sensor (if you’re unsure, check the manual of your video source to determine the IR sensor location).
If the device receiving the IR signal is at the local side
- Connect the IR Receiver to the IR In Port on the HDMI Receiver.
- Position the IR Sensor where you’ll point your IR Remote Control.

Resetting the TX&RX 4) Unplug every cable and re-plug them in the following order: A) Attach an HDMI wire to the display B) Attach an RJ45 cable to the RX c) Connect RJ45 to the TX; d) Connect the HDMI output from the source to the TX; e) Connect the 5VDC power supplies; and f) Reset the RX and TX.
When using extended HDMI cables, a number of conditions call for the use of HDMI extenders. When longer runs are required and the overall image must be preserved, they provide a good ans
With just one Cat6 cable, you can transmit HDMI audio, 1080p, 2K, and 4K video, as well as the IR signal for your remote, up to 220 feet away, and keep all of your video equipment organizedly kept in the basement in a closed rack or cabinet.
While a wireless HDMI extender makes use of the frequency waves all around us, a standard HDMI extender requires an ethernet cable or coaxial cable to transmit and receive data. Similar to how WiFi signals are provided by routers enable our computers to connect wirelessly to other computers and servers
In order to wirelessly transport HD video and audio from your computer, Blu-ray player, or gaming console to your TV, you must use HDMI. You will attach a transmitter and receiver at either end that replaces the long, unsightly HDMI cable in place of the hard-wired connectors.
Where HDMI cables fall short in distance, HDMI extenders fill the gap. The maximum distance that HDMI cables can go without signal degradation is 50 feet. An HDMI extender is a frequent solution if you’ve ever seen your display pixelating, slowing, or even losing the entire picture.
An existing ethernet infrastructure is used by HDMI over Ethernet, also known as HDMI over IP, to deliver HD video signals from one source to an infinite number of screens.
The signal from a single source device will be divided by an HDMI Splitter to enable simultaneous connection to numerous screens. The original signal’s exact replica will be the output signal.
The HDMI connection is converted to Ethernet and then back again at the other end using HDMI extenders, also known as HDMI splitters. This enables you to connect to one or perhaps numerous monitors located hundreds of feet distant, depending on the resolution and frame rate.
This HDMI over CAT5 extender is powered through the HDMI bus and does not require external power, in contrast to the majority of 1080p HDMI extenders, which may need up to two power adapters.
There is no way for the HDMI transmission to be of worse quality than any other cable because it is a totally digital signal.
HDMI cables can experience signal loss at greater lengths, with 50 feet widely regarded as the maximum reliable length, similar to many other audio, video, and data cables. Additionally, it’s uncommon to find an HDMI cable in a retailer longer than 25 feet. Cables longer than 50 feet might be difficult to find, even online.
