rs485+noise
hi to everyone here!
I have query about some noise cancellation technique.
I have ARM kit which is configured to have RS485 communication with an AC drive.
The GND wire between drive and ARM kit is only one, along with 485 cable(approx. long of 1 feet) .
Now when ARM starts communication with DRIVE via 485 , the o/p leds connected to othe port pins get signalled randomly.
This happens sometime and does not sometime.(i.e. randomly.)
How can be tackled with this situation?
Any suggestion will be heartly appriciated!
Thanks & Best regards!
