Do all USB RS232 devices with DB25 adapters work the same, or are there compatibility concerns I should keep in mind if I’m trying to use it with a DB25 device?
Edit: Thanks everyone! Think I've got what I need.

@misty Are you interfacing with something that requires more of the RS232 standard than the typical DB9 connector carries?
I've never encountered stuff that wouldn't work with the signals on a DB9 RS-232. If you have something like that, I'd be surprised if it worked with a USB adapter at all.
And if it doesn't need the DB25, DB9 + adapter (or correctly-ended cable) should be fine.
You def. want an adapter based on the FTDI USB-RS232 IC. The others are inferior.
@ieure Thank you! Checking the list of pins here, these all seem to line up fine with pins that are in the DB9 connector, so I suspect I'll be okay then.
Edit: checking the manual, it seems I misremembered identifying it as a DB25 port? The manual seems to suggest it's 15-pin

@misty Oh, that's odd. Maybe it was a more compact RS-232 connector prior to the DB9 getting adopted widely?
If it is DB15, you might need to build an adapter.
@ieure I wonder! I could see it. Looks like the manual references an official adapter, but I've also found a Pioneer service bulletin with information on the wiring, so I can use that as a reference.
@misty Yeah, they're fairly easy to make, if you're comfortable with a soldering iron.
Happy to help if you could use some guidance with any of that.
