Well, sorta...

There are several versions especially of 9-pin PCB sockets.

Here is what I use:

9-pin: 0.413" radius pin circle, 36 degrees between pins (or, a radial array of 10 pins with one missing). 0.076" hole diameter, 0.15" pad diameter

Octal: 0.500" radius pin circle, 45 degrees between pins (or, a radial array of 8 pins with none missing), 0.100" hole diameter, 0.25" pad diameter

These seem to work with most of the sockets out there. The 9-pins vary by a mm or so but usually can be persuaded to fit this PCB pattern.

Be careful about pin numbers (numbered counterclockwise from the top (socket side) of the PCB).

I have these in a library for Eagle CAD if you're interested. You can download it here:

I'm not sure how accurate these drawings are - but this Headwize design has some Express PCB designs with 9-pin sockets. This should at least point you in the right direction.

Thanks a lot, kstagger
according to pete's website. I will make myself a library in cad...
That would be easy to any PCB. I am gonna test it first, If it was good, I am more than happy to share with anyone.
Thanks
