Hi all,
A follow-up on my problem: today I’ve opened up the belly of the KAT500 and
have done some testing. With no USB cable connected and the KAT500 powered up,
the Q1 drain voltage is 2.39V, where I would expect 5V. Also the gate voltage
is 2.30V, where I would expect it to be floating.

Frank,
I would start with a complete power removal (not just off) to the KAT500
and the computer (unplugged from power). Then go have a cuppa. When
you get back, plug the power in and restart it and test.
I have found that some devices (more in the USB realm) occasionally
'stick' when
Hi all,
I’ve used my KAT500 with pleasure for many years, but recently a problem has
arisen: I’ve lost the serial communication feature. I’ve already swapped the
KXUSB cable with another one (home-brew) so I’m pretty sure it’s not the KXUSB
that’s gone kaput. And the PC is doing USB comms fine
