INTERFACE
This chapter provides the setup procedures for both the SHARC USB
EZ-Extender and EZ-KIT Lite (ADSP-21262, ADSP-21364, or
ADSP-21369) and describes the USB interface the extender supports.
USB EZ-Extender Setup
It is very important to set up all of the components of the system contain-
ing the USB EZ-Extender before applying power to that system. The
following procedure is recommended for the correct setup.
Power your system when these steps are completed:
1. Read the applicable design interface section in this chapter—the
text provides an overview of the capabilities of the interface.
2. Read “System Architecture” on page 2-1 to understand the physical
connections of the extension board. For detailed information, refer
to “USB EZ-Extender Schematic” on page B-1.
3. Remove any rubber feet that may be attached to the EZ-KIT Lite.
In place of these rubber feet, install the four nylon feet and screws
provided with the USB EZ-Extender. Install the nylon feet in the
mounting holes of the EZ-KIT Lite’s printed circuit board (PCB).
Flip the EZ-KIT Lite upside down so that the three expansion
headers (
J1–3) are facing up.
