 		 #166017 - USB and RS485
Responding to: ???'s previous message
Hi Farshad,

You said that your device communicates between a USB and an RS485 bus. Do you physically have an RS-485 cable plugging into your board too?

Also, I believe you said your device is self-powered.

Are either or both of these things true?

Joe
