I have a strange situation with the connectors. This gizmo goes under a model RR layout, and has sensors, speaker, power, etc. hooked up to it. These all come in from different places. The user can field reprogram the unit, which they might do a fair number of times while getting it set up. Each time they do this they have to pull it out and take it to a PC to program it. So either they have to plug in a bunch of things, in the dark, and possibly getting them mixed up, (and the cables can't be given different connectors), or they have to plug them into something and have that something plug into the unit with a single connector. I'm avoiding either ugly solution by using a connector sold as a 2 part terminal block. The header IMC mounts to the board. The screw terminal block plugs into this, and they can be stacked with interlocking dovetails. So, my end user brings the wires togather, interlocks the terminal block plugs, and plugs the whole mass into the card. -- Anniepoo Need loco motors? http://www.idiom.com/~anniepoo/depot/motors.html
