Connector opinions?

IncrdblHulk7:

I was checking out the D-Sub 37 and 50 connector plugs.  I hadnt thought about buying prefab cables and chopping in half.  The only trouble is that on the modular CP end - I wanted panel mounted receptacles for the panels to plug into.  Buying prefab cables would not allow me to do this!  

A side question:  Do I need to run all the Ground wires from Ipac and OptiPac to respective controls - or could I just run a single ground line directly from Computer PS?  Would that cause any problems?

Why not?  Most ribbon connectors have holes on the sides where screw connectors would hold them together.  You could use these to screw into a panel of some nature, or use hot glue or epoxy to affix the end through a hole onto the panel.

Further bonus...multiple ribbon cables of the same type will allow you to run several control panels with the same male end into the one female on your panel.  Just ensure you map the connections well....

AS for the ground, I don't know if you could run the gnd from the PS, but I think you would be better off completing the IPAC circuit from its ground.  

PS...attached is a pic of the rat's nest caused by a thirty-seven pin connector...

Cheers.

I dont plan on screwing the Dsub connectors together when connecting a panel - therfore would Molex provide a better connection?

Here is what I planned to do:

BreakOut Junction from Ipac,OptiPac, DruinRotary Boards -
requires about 72-80 connections
1) 2xDsub37
2) 4xMolex24

Modular CP Hookup
This is a previous post showing the modular panels I plan on building
http://www.arcadecontrols.org/yabbse/index.php?board=1;action=display;threadid=20670
Player1 Controls - 12 inputs + Gnd, 5v, 12V = 15
Player2 Controls - 12 inputs + Gnd, 5V, 12V = 15
P1 Rotary - 12 Inputs = 12
P2 Rotary - 12 Inputs = 12
TB1 = 6 inputs + GND, 5V, 12V = 9
TB2 = 6 inputs + GND, 5V, 12V = 9
Spinner1 = 5 inputs + GND, 5V, 12V = 8
Spinner2 = 5 inputs + GND, 5V, 12V = 8
4-Way = 7inputs + GND = 8

Using DSub - I could combine the respective player and rotary hookups into a single DB25.  So that would result in an interface with DB25x2 and DB9x5.

Using Molex - would result in M15x2, M12x2, M9x5.

Either way it seems like it really just comes down to what connector would provide the best connection and ease of use in this application.

I think I am leaning toward the Molex connectors (solder or crimp connectors???)
