EXTENDER CONNECTOR

The Hirose FX8 120P-SV(91) extender connector is used for

daughter board connections. This allows for additional

functionality to be added to the ezLINX hardware. Figure 16

shows the circuit implementation of the extender connector J23

and J26. Connector J26 is a three pin header connector and

allows for the CAN1 signals of the ADSP-BF548 to be routed to

an external daughter board.

RS-232 CONSOLE

The RS-232 console connector is used for accessing the console

of the uCLinux kernel running on the ADSP-BF548 processor.

It uses the ADM3202 RS-232 line driver and receiver to connect

to UART1 of the ADSP-BF548. The RS-232 signals connect to a

DB-9 connector, J4. A circuit implementation of the RS-232

console is shown in Figure 17.
