This data cable is 6" long and is compatible with a Visor Solo, Deluxe, Platinum or Prism (not Edge.) It has a modem pinout and is powered by the device the Visor is plugged into (see Pinouts, as well as the Product Selector.) Generally, the -M9 and -M9-6 cables are usable in more types of applications than this cable, but it does work with Platinum and for connecting to devices that draw too much current for the Visor to provide it.
