3.4 Programming Cable
The programming cable is used to connect the programming port of the RabbitCore module
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
connector on the programming cable is connected to the RabbitCore
PROG
module’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 programming header of
the RabbitCore module with the module operating in the Run Mode. This allows the pro-
gramming port to be used as a regular serial port.
3.4.1 Changing Between Program Mode and Run Mode
The BL2100 is automatically in Program Mode when the
connector on the pro-
PROG
gramming cable is attached to the RabbitCore module, 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 17. BL2100 Program Mode and Run Mode Set-Up
A program “runs” in either mode, but can only be downloaded and debugged when the
BL2100 is in the Program Mode.

for more information on the pro-
Rabbit 2000 Microprocessor User’s Manual
gramming port and the programming cable.
