Serial adaptor broken?

[m_gustafsson]

Recently my weather system broke down during a thunder storm, and I am now trying to find out which parts were wiped out.
I started by trying to read directly from one temperature/humidity/solar sensor, but can only access it with my USB adaptor and not with my serial adaptor.
Is there anything inside the serial adaptor that can break by an over load?

The 1-Wire driver chip inside the Serial adapter can get fried.

I don't know what protocol the serial adapter is translating (RS232, RS485?), but normally an adapter does perform voltage conversions to go from one standard to another. For example RS232 uses +-12V to communicate, and USB uses 0->5V. If the adapter has to do a voltage translation from one standard to another, not only can it break but may be highly acceptable to power surges. It can also fail even if it has no voltage translation since the logic inside the adaptor may not handle the rise in voltage in the data lines well.

In short, yes it can fail and will depend on how well designed the adapter is whether how acceptable it is to voltage spikes.

Kinda ironic that a weather station fails in thunderstorms.

Thanks,

Thanks :huh:
It actually looks like the serial adapter is broken.
I also believe that the rest of my equipment is safe
So, time to order a new adapter (and one in spare).

P.S. I agree that it is ironic that it breaks during a thunderstorm, that is the time when the weather is most interesting to log.

Just connected my new serial adapter, and it seems like it is now ok again.
Thanks for your support!

Good to hear.
