I need to do some testing on my Stern sound board. (SB-100) I find it difficult to work inside the backbox. I need a long set of cables (36 inches). I thought about making a set of cables with connectors on both ends but the thought of making 64 crimp connectors kills that idea. I have found 16 conductor ribbon cable but I can’t find the end connectors. Anyone have an idea who supplies 16 pin female single row connectors?

Thanks

Bob

Thanks

Do you have a link? All I can find in female connectors is double row.

Bob

Did you use crimp connectors or ribbon cable with IDC connectors?

Thank you

Bob

I think the ribbon cable is the way to go - fast and easy. It's not permanent - just for testing.

Coyote, I found 16 conductor ribbon cable but I can't find 16 pin single row female connectors. Where do you get your connectors?

Thanks

Bob

I thought about using just one row in a double row connector but the way I understand the data sheet is the rows are odd/even. Bottom row would be for conductors 1-3-5-7 etc. Top rows would be for conductors 2-4-6-8 etc.

These connectors must be available somewhere. GPE sells 16 conductor single row ribbon cables. But they are only 13 inches.

Quench, I remember that thread well. I borrowed his cables when I worked on my Magic game.

All I need then is to find 499 other people that need extra long cables.

I don't mind cables end to end. Seems to be the standard anyway. Do you know where I can get the 16 pin single row connectors? I've looked everywhere.

Ed, are the cables you have dis-assemble-able? Could I just re-use the connectors on new ribbon cables?

Thanks Ed,

They are in Taiwan. I sent them a message. Hopefully I'll get an answer.

Bob

If I don't hear back from Taiwan I'll go to plan "B" - make my own from single conductor wire. I just ordered 22 and 24 gauge wire. Which size would you use?

The way I understand the odd/even rows is I would have to seperate each conductor and insert them individually into an odd or even row.

I've seen videos where they used a bench vice to press the wires in the connector. If that don't work maybe the next time I'm in your area I'll stop in and borrow your press.

Thanks

I didn't know about 0.05 pitch cable. Now it makes sense.

More research to do.

Thanks guys.

After more research I found Ribbon cable seems to be 24 to 28 AWG. I couldn’t find any 22 AWG in ribbon cable.

0.05 pitch ribbon cable is 28 AWG = 64.9 ohms per 1000 feet - 0.22 ohms for 42 inches.

22 AWG = 16.14 ohms per 1000 feet - 0.05 ohms for 42 inches.

I was concerned the smaller wire may cause too much resistance in my new 42 inch test cables. I decided to make my own cables using 22 gauge wire. It was a slow process but I now have cables to test sound cards outside the backbox.

One set has two red wires - the other set has one red wire. Maybe that will keep me from reversing them.

I haven’t put them to the test yet but I have a sound card that isn’t working. Once the game is back together I’ll let you know how they work.

Thanks to everyone for your suggestions and input.

Bob
