RS232 receptacle on CCS's CANBUS kit...

Does anyone have the part number and manufacturer of the nifty little RS232 receptacle on CCS's CANBUS kit?

Instead of using your standard 9-pin rs232 cable, they use a plug in receptacle with 3 contacts.

Thanks,
Mike

They use a 3.5mm jack plug on the USB kit, like a headphone connector?

Judging from the photo about half-way down this page,
http://www.ccsinfo.com/canbusdvkt.shtml
those look like CUI 3.5mm jacks, probably with the non-threaded bushing. Here's the page:

There are three different models, depending on whether it has shorting
shunts on it. I can't really tell from the photo. If you have the board
you can tell. Digikey sells these connectors.

Will,
Yes, it looks like a headphone connector.

PCMPro,
that's it! My board has the threaded bushing though. But other than that, the metal inside and their positioning (since the case is see-thru) is absolutely identical.

I forgot to mention that it has 3 contacts.
I don't know what you mean though by shorting shunts.

Go here to the main CUI connector page. It will take you
to the parts with threaded bushings.

"Shorting shunts" was the phrase I used to describe the little
spring loaded contacts that can be used to short the left and
right channel pins to ground, when a stereo plug is not inserted
into the jack.
You might do this if you want to hold the inputs of an amplifier
at 0 volts when there is no audio input. ie., to prevent noise
from being amplified and propagated through the system when
you actually have no input signal connected to your board.

This is irrelevant to the RS-232 usage. You wouldn't need the
shunts in that case.

Thanks for the explanation PCMPro.

CCS did answer me back and told me the exact part number is:

Mouser (and Manufacturer's) Part #: 161-3501

I was curious because i might put this on my first spin of the board for
debugging purposes. Nothing better than a printf() to Hyperterminal to debug problems without interrupting execution of your program.
