HDTV Supplys HDMI Matrix Switch Over Coax extends a single HDMI video and stereo audio signal to dozens of widescreens over a signal point-to-point coax cable to TVs that can be 1,500 feet away. The HDMI Matrix Switch Over Coax provides digital coding processing for HDMI signal with our DTV technology. The HDMI to Coax Splitter adopts our RF modulation technology to transmit the one HDMI signal up to 80 - TVs via a coaxial cable per the TVs HDMI input. No fiber and no special training required as well as you don't have the limitations on distance like you find in HDMI cabling and HD-SDI systems.

This HDMI Matrix Switch Over Coax is designed to convert an HDMI source to an HD digital signal via a coaxial cable. This conversion is different than standard CATV as it uses 64QAM mode to convert the HDMI source to a HD digital TV signal. This type of signal can transmit over long distances on coaxial cable, and gives the user the ability to split and combine several signals with a common CATV splitter/combiner. With the advantages of good image quality, resistance to interference, and hundreds of channels available, it can be used in many applications including: CCTV, outdoor projection screens, shopping malls, advertising, etc.

You set it once with the DIP switches and change the DIP switches when you want to send different sources to different TVs.

By adding the above DTV network mixers (coax splitters) attached in line with the RF cable you can achieve many different kinds of transmission modes like similar to an HDMI splitter operating over 1,500 feet. For example you could configure a 1x25 HDMI splitter for one PC going to 25 widescreens up to 1,500 feet away by wiring one coax cable per TV.

NOTE 1: The HDMI transmitters are very powerful so it can be part of the system to go 1,500 feet. If your distance from your source device(s) are 300 feet, or less, to the passive coax splitter you will need the above 10dB attenuators on each transmitter coax cable. If you need more info, call us.

Our HDMI Matrix Switch is a true HDMI matrix switch allowing any input to be routed to any outputs or the same input to be routed to all outputs, or any of the millions of combinations. See the above FAQ for examples.

What set this HDMI Matrix Switch Over Coax apart from other HDMI Matrix switchers?

The source devices can be over 1,000 feet away from the TVs
You probably can use the home run coax cables already installed
You set it once with the DIP switches and change the DIP switches when you want to send different sources to different TVs
The cost is very low like a 16x16 HDMI matrix is ~$3,500

NOTE 2: The matrix setup using multiple transmitters and multiple receivers is setup via the 8-DIP switches on each unit. The HDMI Matrix Switch Over Coax cannot be controlled any other way.

HDMI to Coax Splitter FAQ:

In normal conditions the transmission distance w/o amplification can be up to 500 meters or 1,500 feet using SYV-75-5 coaxial cables
The signal strength will become weakened after adding DTV network mixers and multiple outputs as used in splitter and matrix applications.
If the signal frequency is high, the transmission attenuation is greater. So choose low channel for long-distance transmission.
When the transmission distance is short (less than 100 meters or 33 feet) the signal may be too strong and the receiver will protect the strong signal and display "NO SIGNAL" to the display. If that is the case you should choose a higher channel via DIP switches or add an attenuator in line with the coaxial cable for signal attenuation.

Our HDMI to Coax Splitter offers solutions for noise, space and security concerns, data center control, information distribution, conference room presentation, school and corporate training environments.

USERS GUIDE

POWERPOINT CONFIGURATION TIPS

Here is an example of setting up an HDMI matrix over coax.

EXAMPLE 1: We have 1-DirecTV satellite receiver and 1-DVD player connected to 4-widescreens that have 500 feet home run RG6 Quad-shield coax cables between the matrix and the widescreens. You will need the users manual for this.

Set the DirecTV HDMI transmitter to CHANNEL 1 ID (00000001)
Set the DVD player HDMI transmitter to CHANNEL 2 ID (00000010)
Set widescreens 1 and 3 HDMI receivers to CHANNEL 1 ID (00000001)
Set widescreens 2 and 4 HDMI receivers to CHANNEL 2 ID (00000010)

You now have set up the following:

The DirecTV is now displaying on widescreens 1 and 3
The DVD is now displaying on widescreens 2 and 4

EXAMPLE 2: In another example we will have 1-DirecTV satellite receiver connected to 4-widescreens that have 500 feet home run RG6 coax cables between the matrix and the widescreens.

Set the DirecTV HDMI transmitter to CHANNEL 1 ID (00000001)
Set the 4-widescreens HDMI receivers to CHANNEL 1 ID (00000001)

You now have the DirecTV displaying on all 4-widescreens as you have changed the frequency to match the DirecTV transmitter box. The important thing to know is if you are constantly changing ins and outs the HDMI transmitters and receivers DIP switches must be accessible as this is the only way to control the coax matrix. Its design is best used where changing ins and outs is minimum. Full control HDMI matrix switchers operated via a remote control or front panel controls can be seen the the above SIMILAR tab.

Hard to understand, do this...hand draw a diagram of the source devices on the left, the matrix in the middle and the widescreens on the right. Mark the cable lengths and what source you want to go to what widescreen. That will get you close to how to set the DIP switches (frequencys). You have 80-input and output frequencys available to you.

Q: Does this HDMI to Coax Splitter have a remote control?
A: No, its inputs and outputs are set with the DIP switches on the side of each transmitter and receiver. When used as an HDMI splitter all DIP switch settings will be the same.

Q: What are the benefits of different frequencies?
A: The HDMI to Coax Splitter supports 80 channels of frequency ranges from 139MHz to 950MHz. If you use many transmitters and many receivers, only the transmitter and receiver have the same frequency as it can receive the signal. This function and anti-interference and error correction allows the unit to work flawlessly.

Q: Any tips you can give me on the install?
A: In-house and existing passive splitters drop the signal strength in half, or more, so delete all of the splitters and wire this device directly as it won't work with coax splitters. They should NOT be used in conjunction with connector adapters, signal processors, switches or amplifiers between the Source and Display device. This HDMI to Coax Splitter sends only one HDMI signal to a TV with the receive unit at the TV. It does not work any other way. If you are trying to send one coax signal to a TV with an HDMI input it won't work. One set includes a transmitter and a receiver set. Think of it as a long HDMI cable.

Q: I need to send a cable box to 12-widescreens over 200 feet away, what do I buy?
A: You will need one 1x16 coax splitter and 12-receivers plus all cables (not supplied). The single HDMI to coax transmitter comes with it.

Q: I have 5-TVs...1-TV 6 feet away, 1-TV 75 feet away, 2-TVs 150 feet away and 1-TV 225 feet away, what do I buy?
A: You will need one 1x8 coax splitter and 5-receivers plus all cables (not supplied). The single HDMI to CAT6 transmitter comes with it.

Q: I need to send a PC to 16-widescreens 150 feet away with all showing the same picture, what do I buy?
A: You will need one 1x16 coax splitter and 16-receivers plus all cables (not supplied.

Q: Sometimes we see a message on the screen "Searching for TX", what is that?
A: That usually happens when the source is turned off or in a standby mode with the HDMI connector not outputting any signal. The (TX) transmitter is looking for a hot HDMI signal on its input.

Q: Does this HDMI to Coax Splitter support 3D or 4K?
A: No.
