DB9 connectors
Locked
 
|
Hi everybody,
Reading the Reflector convinced me that a RS232 connection is better than a USB connection between the K3 and the computer. I recently changed my laptop and succeeded in finding a laptop with a RS232 com port (HP ProBook 650 G1). The problem I'm now facing is that normal DB9 female connectors cannot be reliably inserted in the male DB9 connector of the laptop due to the physical characteristics of the male DB9 connector : there are no nuts on the laptop to attach the connector and the height of normal DB9 female connectors is too big. I looked at many supplier web pages but didn't find a thinner DB9 connector without bolts. Has anybody made the same experience and resolved the problem ? Thank you De Ray, F4FNT ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |

Hi,
Hmm, can you get your money back for that laptop? Seems to me that your RS232 port is next to useless. Even if you could find a mating connector, unbolted DB9's fall out very easily. RS232-less computers is something we have had to live with for a long, long time. It is really not hard to find an FTDI based converter. Avoid the cheap knock-offs, buy locally and return it if it doesn't work. AB2TC - Knut

Ray;
Look closely at the quarter panel. It may slide or snap off to reveal the mounting nuts.

I agree -- I'm looking online, and it appears that the connector is close to being non-functional. > Even if you could find a mating connector, unbolted DB9's fall out very easily. I don't agree with that -- I've used DB9s fully mated without retaining screws with no problems. 73, Jim K9YC ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |

A docking station would provide and RS232 with screw jacks, parallel
port and lots more connectors. Docking stations are pretty nice to have for non-portable use. Just extract the laptop when you need it to go. No unplugging of cables. 73 de Brian/K3KO On 7/25/2015 15:21 PM, Jim Brown wrote: > On Sat,7/25/2015 7:23 AM, ab2tc wrote: >> Hmm, can you get your money back for that laptop?

Docking stations require power, and rarely run from batteries. 73, Jim K9YC ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |

You might try expanding your product search to include the term "DE9"
rather than DB9. The "E" is the shell size and the electronics parts world usually references it this way. Worth a try anyway.
