DB9 connectors

Raymond METZGER
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

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.

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.

I don't agree with that -- I've used DB9s fully mated without retaining
screws with no problems.

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.

Docking stations require power, and rarely run from batteries.

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.
