4.3 Serial Programming Cable
The programming cable is used to connect the serial programming port of the RCM3209/
RCM3229 to a PC serial COM port. The programming cable converts the voltage levels
used by the PC USB port to the CMOS voltage levels used by the Rabbit 3000.
When the
PROG
connector on the programming cable is connected to the RCM3209/
RCM3229 serial programming port at header J1, programs can be downloaded and
debugged over the serial interface.
The DIAG connector of the programming cable may be used on header J1 of the RCM3209/
RCM3229 with the RCM3209/RCM3229 operating in the Run Mode. This allows the pro-
gramming port to be used as a regular serial port.
4.3.1 Changing Between Program Mode and Run Mode
The RCM3209/RCM3229 is automatically in Program Mode when the PROG connector
on the programming cable is attached, and is automatically in Run Mode when no pro-
gramming cable is attached. When the Rabbit 3000 is reset, the operating mode is deter-
mined by the state of the SMODE pins. When the programming cable’s
PROG
connector
is attached, the SMODE pins are pulled high, placing the Rabbit 3000 in the Program
Mode. When the programming cable’s
PROG
connector is not attached, the SMODE pins
are pulled low, causing the Rabbit 3000 to operate in the Run Mode.
