Hello all,

I am creating an application on a PC, using an RS485 USB dongle.

I have only one device connected.

Everything works fine, except...

If I start the application and the device is turned off, after I turn it on, I got this error:

Response not from requested slave

Invalid CRC

...

Response not from requested slave

Invalid CRC

...

Some times it recovers, some times it don't recover

Any suggestion what issue could be?
