4.3 Serial Programming Cable
The programming cable is used to connect the serial programming port of the RCM3900
to a PC USB 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 RCM3900
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 RCM3900
with the RCM3900 operating in the Run Mode. This allows the programming port to be
used as a regular serial port.
4.3.1 Changing Between Program Mode and Run Mode
The RCM3900 is automatically in Program Mode when the PROG connector on the pro-
gramming cable is attached, and is automatically in Run Mode when no programming
cable is attached. When the Rabbit 3000 is reset, the operating mode is determined 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.
