What's not to like, I'm asking in all seriousness? Well, these connectors are REALLY used for currents up to 20 mA or so in phones, and even less in Ethernet (except power over ethernet). Ever had one crackle and have to be wiggled to get a good contact? Our telephone network junction box is exposed to humidity outdoors, and even though those have little foam seals around the plug to try to keep the moisture out, the plug or jack has to be replaced yearly when corrosion shorts it out. Other than equipment that is built with these connectors (phones and Ethernet) I would NEVER use one on anything I built. Jon -- Write once. Port to many.

I can only think of the confusion factor with the true RJ-45 ethernet---but surely nobody would plug their ethernet cable into a stepper :) 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.

Actually this type is the only I have ever used in machines to make different signal wires unpluggable, I haven't found anything that could compete in the ease of wiring (read: soldering), in the pricing. I wanted to write also ease of purchase, but then I remembered that my favorite store had d-sub 25pin females out of stock, when I needed them... Viesturs -- Write once. Port to many.

Speaking of connectors, has anyone considered using RJ-45? it's a proven locking connector that's cheap and rated for over 1A per pin, and the cables are easy to custom-assemble. What's not to like, I'm asking in all seriousness? Basically, both the amperage rating and the interconnector voltages of an RJ-45 would be easily exceeded by most of the motors we use. In my case, the 28 volts = 54 volts peak to peak, a bit above the commonly assumed 50 volts worth of isolation between adjacent pins, not by much, but still... Likewise my 2.74 amps also stretches that current per pin, possibly to the premature failure point again. So no, as a C.E.T., I wouldn't recommend it. What I am using, admittedly at about 10x the cost of an RJ-45, is that 4 pin connector used as a mic connector on CB radios for the last 40 some years. It screws together, so its unlikely to come uncoupled, which if it does while the motor is under power will probably let the smoke out of the drivers. Each contact there can handle 5 or more amps and it is not THAT expensive. A dollop of sili-seal on the back of it and its quite dirt proof too.

Most (maybe all) display cards present normal analog VGA signals on those pins. There are devices (DVI-D) which don't have those pins and are digital only. HDMI is a cable standard which carries the digital part of DVI. An HDMI to DVI cable (or converter) just picks up the digital lines (the dense grid of pins on the DVI connector). The VGA pins from DVI are not connected by an HDMI cable or connector. A HDMI to VGA cable could only work if the device (the motherboard in this case) had some special provision for putting VGA signals onto HDMI pins. I've never heard of that, but it may exist. Sort of like mice that supported USB or PS/2 with an adapter -- that adapter didn't convert from USB to PS/2, it just electrically connected the pins and the mouse itself was capable of doing either. -- Ben Jackson AD7GD b...@ben.com http://www.ben.com/ -- Ridiculously easy VDI.
