Re: Presumed RF Interference

Greetings: We have a client site that is driving us nuts...
That is already half of a solution: Go for fiber. That is imune to both ground and RF problems. Avoid ground connections between the equipment. Replace ethernet with fiber. Break serial lines with optical isolators. Cut the ground wire in your power cords but ground the equipment directly to a metal frame. Avoid ground loops: Between two computers you have a ground connection via the powerline ground. Connect them via RS-232 and you have a second connection via the RS-232 ground. If your power ground is bad then you might run amperes through the RS-232 ground that results in Volts, more than your signal level, maybe. regards Peter and Karin Dambier -- Peter and Karin Dambier The Public-Root Consortium Graeffstrasse 14 D-64646 Heppenheim +49(6252)671-788 (Telekom) +49(179)108-3978 (O2 Genion) +49(6252)750-308 (VoIP: sipgate.de) mail: firstname.lastname@example.org mail: email@example.com http://iason.site.voila.fr/ https://sourceforge.net/projects/iason/
