Question

The input pin on a RUT950 (DIN3) is reading high as low and low as high, this unit was working correctly before.

How does this happen?

Comments

I should note the "Active" high state is set correctly,

ioman.ioman.active_DIN3_status='1'

Hi.

What is firmware are you using? I recommend updating the firmware to the latest and check again, you can download it here

Best regards.

Firmware was latest (RUT9XX_R_00.06.07.5_WEBUI.bin), also tried rolling back (RUT9XX_R_00.06.07.4_WEBUI.bin), same issue either way. I have a feeling a hardware fault has occurred on the input pin due to it not being isolated as this was a test device for an I/O use-case.
