Parallel Port

[TB]

I have bought a Null-Modem Cable. Inside that, ther are 25(!) cables in all colors. I have cut the cable, and I want to know what color what does.
Does anybody know that, or a site from where I can get that information?
Thank you.

Wasn't it better to get the schematic for the cable, instead of wasing money on something you would cut up any way??

[TB]

It costed only 5$.
So, do you know where I can get the information from?

[CyberCarsten]

Ok! Just kidding anyway!
Have you tried the manufacturers homepage, or altavista, search for cable schematics or something like that!

[TB]

I have found some schematics, but not what colors the cables have.

[CyberCarsten]

I must admit, that I don't know much about cables...
But I'm sure the schematics with wire colors are out there!
Good luck!

Colors have no importance to any cable! For that matter, they could all be the same color.
The point is - it's what pin on one end goes to what pin on the other end.
If you wouldn't have foolishly cut the cable you could have done a continuity check
on the pins and found out what goes where.
Somewhere I have a pinout for that type of cable, but it is probably at work.
When I find it, i'll post it

does this help

pin 1  (GND) goes to pin 1  (GND)
pin 2  (TD)  goes to pin 3  (RD)
pin 3  (RD)  goes to pin 2  (TD)
pin 4  (RTS) goes to pin 5  (CTS)
pin 5  (CTS) goes to pin 4  (RTS)
pin 6  (DSR) goes to pin 6  (DSR)
pin 7  (GND) goes to pin 7  (GND)
pin 8  (DCD) goes to pin 20 (DTR)
pin 20 (DTR) goes to pin 8  (DCD)

Thank you.
I have bought the cable to cut it.
I don't use the cable to communicate with a modem, I want to control LED's and some other stuff, so I have to know what colors the Data Bit Cables have.

I have found out what colors the Data Bit Cables have, but I still don't know what the others do.

Ok here is a site which will tell you everything you ever wanted to know about port pinouts.
