PS Configuration Using a Download Cable
In this section, the generic term “download cable” includes the Altera
USB-Blaster universal serial bus (USB) port download cable,
MasterBlaster serial/USB communications cable, ByteBlaster II
parallel port download cable, and the ByteBlaster MV parallel port
download cable.
In PS configuration with a download cable, an intelligent host (such as a
PC) transfers data from a storage device to the device via the USB Blaster,
MasterBlaster, ByteBlaster II, or ByteBlasterMV cable.
