4.3 Programming Cable
The programming cable is used to connect the programming port of the RCM4100 series
of modules to a PC serial COM port. The programming cable converts the RS-232 voltage
levels used by the PC serial port to the CMOS voltage levels used by the Rabbit 4000.
When the PROG connector on the programming cable is connected to the programming
port on the RCM4100, 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 RCM4100
modules with the RCM4100 modules 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 RCM4100 modules are 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 4000 is reset, the operating mode is deter-
mined by the status of the SMODE pins. When the programming cable’s PROG connector
is attached, the SMODE pins are pulled high, placing the Rabbit 4000 in the Program
Mode. When the programming cable’s PROG connector is not attached, the SMODE pins
are pulled low, causing the Rabbit 4000 to operate in the Run Mode.
