3.8 Programming Cable
The programming cable is used to connect the BL2000’s programming port to a PC serial
COM port. The programming cable converts the RS-232 voltage levels used by the PC
serial port to the TTL voltage levels used by the Rabbit 2000.
When the PROG connector on the programming cable is connected to the BL2000’s
programming header, programs can be downloaded and debugged over the serial interface.
The DIAG connector of the programming cable may be used on the BL2000’s programming
header with the BL2000 operating in the Run Mode. This allows the programming port to
be used as a regular serial port.
3.8.1 Changing Between Program Mode and Run Mode
The BL2000 is automatically in Program Mode when the PROG connector on the pro-
gramming cable is attached to the BL2000, and is automatically in Run Mode when no
programming cable is attached. When the Rabbit 2000 is reset, the operating mode is
determined 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 2000 in the
Program Mode. When the programming cable’s PROG connector is not attached, the
SMODE pins are pulled low, causing the Rabbit 2000 to operate in the Run Mode.
Figure 20. BL2000 Program Mode and Run Mode Setup
A program “runs” in either mode, but can only be downloaded and debugged when the
Jackrabbit is in the Program Mode.
Refer to the Rabbit 2000 Microprocessor User’s Manual for more information on the pro-
gramming port and the programming cable.
