Usage Of The USB PowerPC Nexus Multilink
Interface
The USB POWERPC NEXUS MULTILINK can communicate with a PowerPC 55xx processor.
The Multilink interface will work with targets whose processor power supply is in the range of 1.8V to
5.25V. The Multilink interface derives its power from the USB port, and as such draws less than 10mA
from the target.
The USB PowerPC Nexus Multilink has a female, Type B USB connector. Use a Type A to Type B USB
extension cable to connect the interface to the PC. The USB PowerPC Nexus Multilink is a high-power
USB device. If a USB HUB is used, it must be a self powered hub (i.e., with a power supply). By default,
the USB protocol used is 2.0.
There are two LEDs located on top of the USB PowerPC Nexus Multilink interface. The Blue LED
indicates that the Multilink interface is powered and running. The Yellow LED indicates that target
power has been detected.
The 14-pin ribbon cable, which allows connection to the target debug connector, is fixed within the
Multilink housing. PIN 1 is indicated by the red stripe running down one side of the ribbon cable.
