Hi All,

After having killed my notebook with a servo drive failure 'spiking' the serial port, I am looking for some way to have some isolation on the comms port. I was wondering if anyone has been using a device to achieve this.

Cheers,
Trevor Ousey

It could be your notebook adapter that is the culprit. Some are 2 wire mains with no earthing. check with a line tester. Switch to a 3 wire.
