The "D" refers to the shape and the "B" refers to the shell-size.
Hence,
your typical RS-232 cable has a DB-25, indicating a D-connector with a size
B shell with 25 contacts in it. They are further designated 'S' for socket
(female) and 'P' for plug (male), which is not too hard to figure out.
Likewise, the floppy disk cable connector formerly seen on PC FDC's used a
DC37S connector, and what's most often seen on SCSI equipment attached to
SUN systems is a DD50, though I can't remember which sex goes on what. The
smaller serial connector now common on PC's is a DE-9, and the 15-pin
connector used for joystics and MIDI is the DA15. On the other hand, the
VGA connector would be a DE15, though I can't say I've ever seen it called
out that way.

Subject: i'm confused..
Hello,
This is probably a dumb questions, but i'm unsure of what a "D-type
b-miniature connector" is. I'm trying to connect my PC's serial port to my
VAXstation 3100, and the H8571-J adapter converts the 6-pin MMJ port to a
"D-type sub-miniature connector." Is that simply a fancy word for a female
serial port?
Thanks in advance. :)
-Jack
