3.4 Programming Cable
The programming cable is used to connect the programming port of the OP6800 to a PC
serial COM port. The programming cable converts the RS-232 voltage levels used by the
PC serial port to the voltage levels used by the Rabbit 2000.
When the PROG connector on the programming cable is connected to the OP6800 pro-
gramming port, programs can be downloaded and debugged over the serial interface
between the PC and the Rabbit 2000.
The DIAG connector of the programming cable may be used on header J1 of the OP6800
RabbitCore module with the OP6800 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 OP6800 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 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 15. OP6800 Program Mode and Run Mode Set-Up
A program “runs” in either mode, but can only be downloaded and debugged when the
OP6800 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.
