I recently purchase a used TSU9400 remote on eBay. It looks in very good shape and after downloading my configuration file, everything seemed to work perfectly. 99% of the commands that I execute are WIFI-to-extender-to-equipment in the basement.

Every now and then, I use ‘line of sight’ IR to something in the room, say a portable fan. For my three other TSU9400’s, this works perfectly and the fan (or the other line-of-sight IR equipment) will accept the direct IR code. For the new remote, nothing happens.

I’m assuming the worst; that the IR transmitter in the TSU9400 is broken, but thought I would check and see if it might be something else.

Get a digital camera and look at the screen/view finder while pointing the TSU9400 to the lens.
You should clearly see the IR LEDs light up on the camera screen when you send an IR command.

I remember reading somewhere that this would not work with an iPhone as those allegedly filter out the IR range.
I did check with my iPhone 12 just now and I could see the IR LEDs on my TSU9800 light up, though, so this might not be a thing anymore.

John,

I know you've been here a long time so please forgive me if you already know all this. I suspect you do but have to ask....


Presumably, you are using PEP2 or PEP3. What you did not mention is if on all 4 TSU9400s you are using the same configuration file.

When line of sight does not work it usually means that you have a component in your configuration (Equipment tab of Building Blocks) that is set to use an extender vs direct ir. To set to use direct ir, click on the component to highlight it and then look at the right-hand side of the screen where the extenders are displayed. If there is a box checked for any extender, that is the problem. That component is sending to an extender and not line of site. Uncheck the extender and it should work.

Thanks Sebastian. I will give it a try.

Lyndel. Your response was right on target and when this particular remote did not work, that was the first place I looked. Unfortunately, none of the extenders were checked. I then downloaded the same PEP3 configuration file to all 4 TSU9400s. Line-of-sight works on all the other 3, but not the one in question. With that said, I appreciate the response.

I followed Sebastian's suggestion using my iPhone 12. The IR LED lit up on a working remote, but did not on the remote in question. While not ideal, at least now I know it is very likely a hardware issue.

I've always wanted to take one of these apart using jwatkins80504 'disassembling the TSU9400' instructions. Now I actual have a reason to!

Thanks again Sebastian and Lyndel.
