I much prefer d-sub connectors. They're inexpensive, the ear screws are a positive closer, strain relief is robust, they often need no special tools to build, they are easy to shield and, leaving a pin or pins out, can be easy to key matching connectors. RJ connectors are cheap, the lock breaks easily, the lock allows contact movement, strain relief is meager, mostly needs a special tool, shielding is less common, keying options are very limited. I think d-subs convey to customers a commitment to quality that RJ's don't. Of course, just my opinion. -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/index.html California, USA ------------------------------------------------------------------------------ Write once.
