If you connected the Multilink interface prior to installing the drivers, Windows will not have been able to
find the appropriate driver and may have disabled the device. If you unplug and reconnect the device,
Windows will automatically disable it even if you have installed the drivers. To force Windows to try to
load the driver again, perform the following steps while the USB PowerPC BDM Multilink interface is
plugged into the computer:
1.)
2.)
3.)
4.)
5.)
Open the Control Panel (Start Button->Settings->Control Panel)
Double-click the “System” icon
Select the “Hardware” tab
Click the “Device Manager” button
The “P&E PowerPC BDM Multilink” device will be shown with an exclamation mark next to
it. Double-click this device.
6.) Click the “Reinstall Driver… ” button and follow the dialog instructions to have Windows
automatically install the driver.
If you have purchased one of P&E’s software development packages prior to July 1, 2005, contact P&E to
obtain the latest version which supports the USB PowerPC BDM Multilink interface (software support
for the cable is separate from Windows USB driver support). If you are using third-party software, make
sure you have a version which supports the USB PowerPC BDM Multilink interface.
4.0 Computers Running Windows 95, 98, ME, or NT
The USB PowerPC BDM Multilink is not supported under Windows 95 or NT. The USB PowerPC BDM
Multilink is not tested under Windows 98 and Windows ME, although drivers for these operating
systems are included in the install. For these operating systems, P&E produces the Parallel Port
CABLEPPC which connects the parallel port of the PC to the 10-pin debug connector on the target. For
more information, visit http://www.pemicro.com .
5.0 Using A USB Hub
The USB PowerPC BDM Multilink is classified as a high-power USB device which is powered from the
USB bus. A high-power device requires that if a USB hub is used, it must be a self-powered hub. This
means that it has a separate power supply from which it derives its operating power (as opposed to
deriving its power from the PC). It must be able to supply 500mA per port (a high-power USB device may
derive up to 500mA from the port).
6.0 Connecting To The Target
The following is the proper connection sequence to connect the PC to the target system via the USB
PowerPC BDM Multilink interface:
1) Make sure the target power is OFF and the USB PowerPC BDM Multilink is not connected to
either the target or the PC.
2) Connect the Multilink to the target via its ribbon cable. Make sure that the ribbon cable is plugged
into the target with the proper orientation. PIN 1 is indicated by the red stripe running down the
ribbon cable.
3) Connect the Multilink to the PC via a USB extension cable. This should light the Blue LED on the
Multilink.
