RS232/USB cable for legacy Predator

[Troysterr]

I haven't used my Predator tuner for almost a decade, but I need to use it now, but I can't find my RS232/USB cable. Does anyone know if it's a proprietary part, or if I can use any generic RS232/USB cable, like this one?

You can use a generic USB-to-RS232 cable if it uses an FTDI FT232R or Prolific PL2303 chip (FTDI is preferred for better compatibility).

it needs to be a straight through type.

FWIW, DSDL is no longer around, can find it here on the forums but hasn't been supported for a while.
What do you need to do with the Predator?
