Page 16: Connect Programming Cable
2.1.2 Connect Programming Cable The programming cable connects the RCM2100 module to the PC running Dynamic C, to download programs and to monitor the RCM2100 for debugging. Connect the 10-pin connector of the programming cable labeled PROG to header J5 on the RCM2100 module as shown in Figure 3 below. -
Page 17: Connect Power
To power down the Prototyping Board, unplug the power connector from J5. You should disconnect power before making any circuit adjustments in the prototyping area, changing any connections to the board, or removing the RCM2100 module from the Prototyping Board. RabbitCore RCM2100... -
Page 18: Run A Sample Program
2.2 Run a Sample Program Once the RCM2100 is connected as described in the preceding pages, start Dynamic C by double-clicking on the Dynamic C icon or by double-clicking on dcrab_XXXX.exe the Dynamic C root directory, where are version-specific characters. Dynamic C XXXX uses the serial port specified during installation. -
