Depends what exactly you are doing with it, it's hard to give blanket advice about something like that. You need to decide up front if you want your (presumably) metalic enclosure to have electrical connection to the GND potential of the 4826. Choosing that this should _not_ be the case puts your soekris at a healthy danger because it will have to take all static electricity spikes on its own, whereas if you keep a common reference potenential for the entire enclosure the box will usually take the hit. Having decided what to do about your reference potential, you need to figure out how to do it. A metalic mounting plate with metalic spacers is normally an OK reference connection, if you use isolating spacers or isolated mounting plate, you would need to add a wire from one of the mounting holes on the soekris to your reference potential. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 [EMAIL PROTECTED] | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence. _______________________________________________ Soekris-tech mailing list [email protected] http://lists.soekris.com/mailman/listinfo/soekris-tech
