HELP Seiko S129 / S149 data output jack

I added some memory to my interface this winter and have just sent my final version for someone else to do some testing. I did my own testing during a Nationals X-country ski race early in March and it worked very well. The connector to the Seiko continues to be the challenge. It is definitely the most difficult part. I would make more of these interfaces if someone could provide the connectors.

Is there another connector more common that would replace the seiko one. A mini DIN would fit the case with modifications. Since Seiko has not chosen to develope this feature of the watch maybe keeping it is the wrong approach?

Hi this post is quite old but i am hoping someone can help me with the pinout configuration of the seiko device and encoding scheme for bytes received through the rs232 interface. Thanks Mark

Mark I received an email but the address you gave is incorrect so I'm unable to reply can you send another email.

I have a lot of time into this interface and I can tell you that it is not just a cable that is required. You would need to have a good understanding of a micro controller because you need to read a 4 bit data bus.

Let me know if you are still interested.

Thanks for the reply. I have posted a reply on your sports site again.

Has anyone had luck recently sourcing the plug which fits. I havent tried Harold as yet.

Luc G is the TX pin standard RS232? Not sure what you mean by 4 bit bus. I am familiar working with rs232 and micro controllers.

It has been a long time since I tried Harold. No luck. The most information I got was that there were a few connectors left from an original manufacturing cycle but they were not for sale. It might be worth trying again.

I can provide the technical detail if you provide an email or other contact info.

I guess I should add that I am not sure I would spend more time with this because you can get the same functionality from many other units. I use Summits with a seiko printer almost exclusively now. RFID has become very affordable and easy to use so I merge the two systems to get the bib number form the RFID and the accuracy from the Summit timer.

Although.... the Seikos are nice and simple.

Thanks luc g. You can reach me at markp2510@gmail.com

Hi Luc,
Slightly off topic, can you give me detail of the "affordable" RFID units you are using for bib recognition?
Many thanks
Graeme

I am interested in the serial cable info and might be interested in making a cable. You can also build a cable to connect the seiko S129 to the computer via the 25 pin connector by just splitting the cable up.
