Re: [time-nuts] Jupiter GPS 10 KHz pin
David, On the site http://gpskit.nl/, in the downloads directory, you can find a lot of info on the Rockwell Jupiter board. I know the info you are looking for is in there somewhere.

Would someone with a Jupiter board trace the connection from the 10 KHz output back to the pin on the chip it originates from? That would be a huge help. I suspect that you'll find it ends up on the chip labeled 11577-11.

Re: [time-nuts] Jupiter GPS 10 KHz pin
Tom, Thanks for your reply. I looked through the documents on that page but unfortunately I don't think any quite address my question. I think they'd have to have a schematic of the board itself to do that. If someone would just stick a multimeter probe on the 10 KHz connection of their module and then trace that signal back to the IC, I would really appreciate it.

Maybe I can find it and ID the pin for you. -- newell N5TNL ___ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
Re: [time-nuts] Jupiter GPS 10 KHz pin
David, If I hold my Jupiter in the position where the connector is on the left and the 11577-11 is facing me then the 10kHz is on pin 20 of the connector (top right) and this pin is connected to pin 13 counting from the top right-hand-side of the IC. In some ugly ascii graphics: -- | Jupiter board | o o=Pin20 - top | o o | o | 1 | o o | | 2 | o o | | | o o | 11577-11| 13=10kHz | I can only hope this is readable in your mail program ;-) Let me know if this comes out OK. If not I will do some photoshopping :-) Tom ___ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.

Thanks for your time, David Carr David On the TU30-D165 version of the Jupiter the relevant pin appears to be the 13th pin up from the bottom on the LHS of the large chip in the attached drawing.

Re: [time-nuts] Jupiter GPS 10 KHz pin
David, I can confirm. I measured it on a TU30-D140 and its on the same pin. Bruce's graphic is rotated 180' compared to my ascii graphic.

Re: [time-nuts] Jupiter GPS 10 KHz pin
Tom and Bruce, Thanks for probing out this line for me. You two are indeed correct, as I found a nice looking 10 kHz signal on the pin you identified. My GPS is a TravRoute CoPilot serial hockey puck which happens to have a Jupiter chipset (FW 1.83 1997). I thought that this GPS (my first) was about done, but I think its found some new life...
