- Rio 500
The Rio 500 is considered the first of the Second Generation
MP3 digital audio player (portable digital audio player), and was produced byDiamond Multimedia . It shipped in 1999. The Rio 500 was the successor of theRio PMP300 , and provided a number of user requested features (including USB and higher audio quality).Features
The Rio 500 was the first MP3 player to allow file transfer via
USB cable, and PC & Mac support. It features 64 MB of flash memory available for music, has a backlight, ability to set bookmarks, has an expansion card slot (Smart Media card) and is powered by one AA battery. It is roughly the size of a standard pack of playing cards.Non-standard USB
The data lines are reversed and the +5V line is not connected. Several models of digital cameras used a USB cable with a connector that fits the Rio 500 and already have the data lined reversed. They can be identified by the arrow on the small connector rather than the USB "trident" logo. These cables must have the +5V line (red wire) cut for use with this player. One source for these cables is
Radio Shack , but they're expensive.
