Computers Running Windows 98/ME
The USB BDM MULTILINK is supported under Windows 98 and Windows Millenium Edition (ME). The driver
installation is similar to that of Windows XP/2000/2003/Vista/7.

Computers Running Windows 95/NT
Windows NT and Windows 95 do not have support for USB, and therefore the USB Multilink is not supported under
these operating systems. For these operating systems, P&E produces the BDM Multilink, which connects the
parallel port on the PC to the 6-pin debug connector on the target. For more information, visit:

Using A USB Hub
The USB BDM MULTILINK is a USB device which is powered from the USB bus. It requires that if a USB hub is
used, it must be a self-powered hub. This means that it has a separate power supply, as opposed to deriving its
power from the PC. It must be able to supply 500mA per port.
