38 RabbitLink (EG2110)
The DIAG Connector
The
DIAG
connector is used to configure network parameters for the RabbitLink. It is also
used to treat the programming port as a regular serial port; because the programming cable
contains an active circuit board that converts RS-232 voltage levels used by the PC serial
port to CMOS voltage levels used by the Rabbit, the
DIAG
connector allows the program-
ming cable to be used as an RS-232 to CMOS level converter for serial communication.
The /RESET line and the SMODE1 and SMODE0 pins are not present in the
DIAG
con-
nector.
