TL-POE150S does not show a detection signal
Hi there,
I am testing your TL-POE150S with one of my devices, but the power line of my device is allways 0V. I took a look with the oscyloscope at the voltage between the pins 7/8 and 5/4 of the ethernet cable that comes from your device since I expected to see a detection signal of 2-10V once i plug it to the power or after a while. But i dont see anything.
Can you help me here?
Thank you so much in advance.

After some testings i see that the signals your PoE device is using are the 1/2 and the 3/6 ... so it is a Mode A device, not Mode B. Do you have any device that operates in Mode B ( pins 4/5 and 7/8) ?

@NasCraftsman After manually modification of the ethernet cable i got:
A detection voltage of : 3.8V
A classification voltage of: 7.8V ( what in my opinion is not correct )
A supply power of 48V
But after 500ms of the 48V power delivey, the process starts again.
What is happening here ?
