Title: Parallel Cable cut away
Post by: GGKoul on February 19, 2004, 02:39:16 pm
Hello

I search the board & internet and I couldn't find the answer to this.

Can someone send me a link that describes what wires are in a parallel cable?  As I planning to create multiple panels and I want to connect the panels via a Male & Female parallel cable.

So each panel will have a Male parallel cable to connect to the Female connection from the IPAC.

Any advise you have will be greatly appreicated!!

Thanks!

There's no standard for the actual cable itself.  However, the port pinouts are in these places:

There's just 25 pins/wires.  Do with them as you please.

So the Pins on both the Male & Female cables don't have to match?

IE:  Pin1 Male to Hole1 on Female?

I mean this..  A wire a on connected to the male end is pin 1 and wired to UP... Hole1 on the female is wired to the IPAC as Button1.


So they dont have to match?

So I'm wondering... Is there a document that says

White Wire is Pin 1
Blue Wire is Pin 2

Yes, the pins have to match, but pin 1 male may have a purple wire connected to it and female 1 may have a yellow wire.  There's no standard.  The best way to do it is to cut off the end of the female and the male, then strip back the insulation on all wires on the male and female, and use a meter to check continuity and label the wires somehow.  It's a long process, but the best way I know to ensure you have the right connection.  Let's say you hook the purple pin 1 male wire which is connected to pin 1 up to button 1.  Now the purple wire on the female side may be connected to pin 17, and if you hook that up to your IPAC on button 1 it won't work correctly, because it's looking for whatever is coming into pin 17.  It's hard to put this in words, but I hope you understand.

From what I've seen, there is no industry standard.  It's left up to the cable maufacturer, so unless you have the same brand cable chances are you won't be able to rely on wire color, and even if they are the same manufacturer there's no guarantee they used the same color wire on both cables.

Unless I purchase one cable that is Male on one end and a Female on the other end.

an easier way would be to buy 2 female DB25 connecters with crimp pins from radio shack. wire the pins yourself so you know what they are, then connect the 2 with a double male cable.

My local Radio Shack doesn't have them...  I have to check else where....

if i'm reading your question correctly......

the wires inside the cable should all be color coded(at least all the cables i've used have been). once cut, and  you have the connectors together the wires of the same color should have continuity.

ie.  if a wire that is yellow/black stripe is connected to player one fire button.......then yellow/blk stripe(coming from the opposing connector)  should be connected to the player one fire input on your encoder.

hope this helps.

Use a 25 pin serial cable.  That should have male and female ends.  Then your color coding issues are over.
