ATX Board doesn't work

KVM
1

I am using a Comet PoE and can not get the ATX Board to work

I have tried almost all combinations of connecting the ATX Board and none of them allow to to pass the Power or Restart commands. I have tried interface 4 and 5, swapping the polarity of the power pins (ATX Board to motherboard), only plugging in the power pins, removing the case front panel connection and none of them make the power options work. When connected the pass through from the case does work and so do the power LEDs. I saw in another threat that it might be the usb cable but I swapped it with the one for mouse and keyboard that did work and still nothing. I am using a z690 pg riptide motherboard.

Looking at that diagram of my panel header layout I tried 3-4, 4-3, 3-8, 8-3 and none worked.

txpower /dev/ttyACM0 power_state

on

This indicates that the RM1PE and ATX connections are normal, and the problem lies in the connection between the ATX and the computer.

  1. Try re-plugging all the DuPont cables to avoid the problem of poor contact.

2. Try to execute atxpower /dev/ttyACM0 click_power_short, and observe whether the controlled computer turns on/off. If not, try the following steps.

3. Try reversing the polarity of POWER SW, Try step 2 again.(The pins connect to the motherboard )

If the ATX still doesn't work, try using a multimeter to measure the connectivity between the ATX and the computer.

I've reviewed your logs and descriptions. Unless you can test it on another computer to confirm whether the ATX unit itself is faulty, I don't have other solutions to offer.
