Re: house connector block & DB25

Hi Bill,

Thanks for the link. That sure was a long url, clicking didn't work,
copy&paste directly into IE address didn't work, copy&paste into
notepad, then into IE address did, but somehow gave the wrong page.

Your last tips finally got me to the relevant page.

Thanks. (how will we ever manage without a group like this???)

BTW That connector says "shielded" which means that if we have to use
connectors like this, noise is expected to be a problem? Then what
about the break-out boxes offered by Camtronics and CNCkits? Are they
also shielded too?
