GL-ATXPC May have a design issue

[rahlquist]

Hello,

I recently purchased the GL-RM1PE and GL-ATXPC. I already own a GL-RM1 and am quite happy with it. When I setup the GL-RM1PE it worked fairly simply out of the box, and I was pleased. Today I unboxed the GL-ATXPC and tried to add it to the configuration

. I had no issue with the hookup. When I tried the power button on my machine it worked the power up the computer, but the power LED did not illuminate. Thinking I had made a mistake with the polarity, I shut everything off, and swapped the polarity for my power LED, and powered things back up. Unfortunately it still did not illuminate. So I unhooked the leads from the motherboard for the power LED, and reattached my original power LED leads to the motherboard and they worked as normal. I reattached the power LED leads that came with the GL-ATXPC and the Green and Blue LED on your board illuminated. Then I hooked my cases power LED to the GL-ATXPC and in a dark room could see my case LED illuminating very dimly. So Dim I would not be able to see it during the day. I removed the case power LED leads and connected them directly to the header where your leads were attached to the board, my power LED illuminated.

I believe that your GL-ATXPC board is not passing enough power from the motherboard back out the other header. I hooked the HD LED to the power LED points and it illuminated dimly, though slightly brighter (the HD LED is a simple red one, the system power LED is a normally very bright blue). I have not taken the time to get a meter out, and diagnose it further. I have ordered a second GL-ATXPC board from amazon and it should be here tomorrow. If it performs the same then your GL-ATXPC board is consuming the power LED power rather than simply passing it through.

Also what do the green and blue LED on the GL-ATXPC board mean, I can find no documentation or notes on what they are being used to indicate. Please update the documentation for the product to explain their use and what they mean.

Thanks,

Richard

Thanks for your detailed report. We are still finding ways to improve this aspect.

Power LED passthrough from ATX board doesn't work quite right

Hi Thanks for your feedback. We have two leds on the board and the both led behaiver is the same as the Power LED(blue is system for ATX; green is power for PC) , we didi't have HDD LED on the ATX board. There is a Optocoupler on the ATX board, and inside the Optocoupler there is a LED; so if you plug the right polarity the power LED will work good. otherwise the led won't work.

Further details.

Open Circuit voltage from PC for power LED 4.934v
Current Draw of RED LED 2.27mA
Current Draw of BLUE LED 3.90mA

Once I add the board to the circuit.

Output voltage with original board 2.462v
Output voltage with replacement board 2.176v

So yeah, 99% likely that large voltage drop is preventing the Blue LED from working.

So is there a solution being sought? Or is it something you consider too much of an edge case to address? Perhaps consider a notice on the product that it may not be fully compatible, just so people won't be caught off guard.

Sorry for the inconvenience caused.
Our engineer are working on to find out a solution, there are some useful solution but still need more test. Please kindly wait.
