Default Connectors for baseboards

Ok, well not exactly on the workbench. Here is a photo of the connectors I have made for joining up the two boards of my new layout. They are each 15pin. One is for the 5 servo cables that need to come over and the other for everything else. I have 4 spare pairs of wires connected for anything that occurs to me later.

At present they are bound by cable ties as I still need to source some of those curly cable tidy things and the tethers, which go through the hardboard base the choc blocks are secured to, are the same system. I have some large grey twin and earth cable clips that I will use as additional tethers when the cables are on the baseboard.

It does look a puzzle, doesn't it? For the servo connections there are three wires per motor, and there are plugs one on side and sockets on the other. Control wires from the motor terminate in a plug, so the other side needs to be sockets - so that's straightforward enough.

The other set of wires are connected by number with pin 1 noted on each choc block. You might be able to make out my notes on the hardboard backing. Later on, for the last two I made, I realised that if I put a black wire on GROUND (position 16) I didn't even need to notate the choc blocks as pin 1 will always be at the other end.

It is not possible to connect them incorrectly as the male/female pluggable components are reversed for each set. I realise that there are servo cables on one set but when they are on the baseboard you won't be able to see them.

Hope that makes sense.

Pin 1 to terminal 1, Pin 2 to 2 etc. No need for colours. You probably wouldn't have enough colours anyway. If wires are not labelled then bell test them to determine connections as need be. Bell test = use a multi meter on continuity or a battery powered buzzer etc.

So do I - if they are secured then it should not be more than one at a time, I hope, so easy to see and deal with. R-

I used my meter on the continuity setting to test the whole set-up plugged together for good connection and the ensure that each wire was going where I wanted it to go. I'm pleased to say that after 120 connections it all tested perfectly. R-

Either end really. But all solveable. R-

I guess so. I would have labelled each wire.
