THAT one is labelled "RS232C"!!!
I asusme
it's the PC/AT serial port wiring. Althought i thought that
RS232C actually specified the DB25 conenctor.
and I have NEVER seen a DE15 used for any kind of serial.
Considering that these cables probably came from an LCD projector, it is
PROBABLY a monitor adapter of some sort. Somebody clueless may have
looked at the DE9 and automatically labelled it as "RS232" (as a misuse,
meaning serial)
Err, not necessarily. I'm rather thinking that the corresponding LCD projector
("beamer") might have included or at least supported a "presenter",
i.e. a wireless, handheld mini-trackball or hat-switch type pointing device, whose signals
are relayed to the host system via the respective pointing device interface.
As only one of these interfaces is needed at a given time (ADB when connected to a Mac,
either RS232 or PS/2 for a legacy PC, or USB for a modern one), it kind of makes sense to
bring these out in a single connector (in this case, the DE15) and include the different
adapter cables for connecting it to the host system.
I got a similar set of cables some years ago, these had a not-quite-MiniDIN connector at
the projector end and either DE9, MiniDIN-6 or USB on the other. They were factory
labelled as belonging to an ASK C105.
If so, very usefor for somebody having the corresponding projector, not so much for anyone
else.
Hope this helps - so long,
