The board is now ready for operation under the control of the debugger as described in
.” If you do not get the above response, perform the following checks:
1. Make sure that the power supply is properly configured for polarity, voltage level and current
capability (~1A) and is connected to the board.
2. Check that the terminal and board are set for the same character format and baud.
3. Press the RESET button to insure that the board has been initialized properly.
If you still are not receiving the proper response, your board may have been damaged. Contact Rapid PCB
for further instructions. For contact details, see the front of this manual.
