the serial DB-25 plug is long retired, but the DB-9 is still frequently used though.
ARGHH!!!!
It's "DE-9". There's no such thing as a "DB-9". The 2nd letter refers to the shell size. The 25 pin connector uses a "B" shell, the 9 pin, "E". Another popular connector is the DA-15 which was used for joysticks etc. That wikipedia link lists the various shell sizes with common uses.
And to think, I could have gone my whole life wistfully oblivious to the fact that the 2nd letter referred to the shell size of the connector.... God I love this list :) Thanks James ;-)
Years ago, I used to work in planning for a large telecommunications company, where I ordered connectors by the 1000's. I wouldn't have had much luck ordering the wrong item. Industrial supplier catalogues list the correct part identifier, but those selling to the public use "DB-9", because they have to deal with the ignorance of the general public. Incidentally, the first letter "D" refers to the connector series (the shells are sort of D shaped) and of course the number refers to the number of pins. I suppose, if you wanted to spend the money, you could get a connector manufacturer to make a custom 9 pin connector in a DB shell. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
