Input:
Question: Does the HDMI source component need to be powered on for IR to transmit?  (DVD direct wired to projector)
Document: If you don't have extra space (for example, if one end of the wire connects to an HDMI splitter) then you will need some swivel adapters to give your plug more flexibility. You should check your setup before you buy, and maybe buy some just in case anyway.Lastly, the product doesn't come with any instructions, but it's pretty simple to set up. Just remember that "RX" is receive and "TX" is transmit.
So at first, I did not realize the IR receivers were different. One is meant to receive a signal from remote and the other is to transmit signal to source/cable box. See the arrows on top of the IR receivers to know which one is which.I'm curious if anyone has used this product for Playstation 3 controllers and if works. I would like to be able to hide the video game consoles in the closet too.
This does exactly as you would hope it does. I have a HTPC in my bar and I ran a splitter with this wire to my living room. Now I can use the remote to control the source from many rooms away. It's also great for parties when you want the same picture and audio on multiple sources but controlled from any room. Just make sure you get a good powered splitter. The only issue I am having is that once in a while the audio track cuts out.
This product worked great for our setup. I was using older IR transmit/receive extenders on multiple TV's on 2 floors. Sometimes they worked and sometimes they didn't!. We have 5 TV's running off of one Directv TIVO receiver all in separate rooms. I installed a 1x8 HDMI splitter and installed the IR extender on each HDMI cable and they work perfectly. The only thing you may have to add if you have more than one extender is an angle HDMI connector or swivel connector.
I was able to use this to control a tv with components and Logitech Smart a Control all concealed in a cabinet. This also continues to work even when TV is receiving input from a component device. Simple to set up, but I did need a 270 degree adapter due to the space behind the tv being too narrow.
Easy to plug in to 2 ends of HDMI I already had run to other room. Works for both TV and DVD player.
Great product at a great price! Controls our Verizon FIOS DVR located in a remote closet like we were sitting in front of unit. Best of all, extender is powered by HDMI ports so there were no power adapters to worry about.
If you need to troubleshoot you can use a phone camera to test the transmitter, most digital cameras should pick up IR signals and display them as a white/red light.
This is the 3rd IR extender I have tried and it is the best so far. is it made from the highest quality material, no. does it ship with setup instructions, no. pretty easy to use and setup is self explanatory. if you are looking for a device that will constantly need to pulled and toyed with then keep looking. but if want to setup the device and forget about touching for a few years then who cares about the quality of the material construction.
I needed this to work my cable box that is being blocked by a couch. I wanted something that was discrete. This was a perfect choice. I'm using a 2 Monoprice HDMI cable ran over 15'. I mounted the receiver on the top of my flat screen. I used a piece of velcro to hold it to the top in case I have to remove the TV. The 2sided sticky tape that comes with this is worthless, so you'll need better mounting tape/glue.
Answer: I will explain our situation and hopefully that will answer your question.We have the receiving side of the cable on our Samsung TV and the "blaster" side in front of our Tivo. Both devices are on different floors of our house so I know the Tivo is not receiving the signal by accident. With both devices turned off (wich for Tivo actually means "standby" just like about every cable box in the market) if I send a signal to the receiving side of the cable the Tivo will receive it, even if I have not turned on the Samsung TV. Of course, I have to turn on the Samsung to see that Tivo received it, but when I do, I can see that Tivo received the signal and executed the command I gave it. Therefore, I believe the answer to your question is probably "No, the component does not need to be power on for the IR to transmit, but beware that the component must have a CEC connection as part of its HDMI connection and the HDMI cable must also have the CEC wire." I am not a technical person, but I believe the reason is that the CEC connection is always "on", although at a low power consumption state, even when all the devices are turned "off". That allows the CEC wire to be used to transmit information even when the device that has the receiving side of the cable is turned off.
