Setup:

1) Power off everything.

2) Install THERMOCOUPLE-1 board on top of DAQ-2543. Use our spacer kit if needed.

3) Install DAQ-2543 + THERMOCOUPLE-1 combination on top of MINI-MAX/51-C2. Use our spacer kit if needed.

4) Connect your thermocouple(s) to the terminal blocks on THERMOCOUPLE-1 board.

5) Configure the jumpers on THERMOCOUPLE-1 board for your thermocouple type ( e.g. J, K, ... )

6) Connect the MINI-MAX/51-C2 to your PC's serial (COM) port using the serial cable of MINI-MAX/51-C2.

7) Apply power to the setup.

8) Start Micro-IDE on your PC.

9) Open tlc2543 project from examples\adc\tlc2543 and download to the MINI-MAX/51-C2.

10) Open the terminal window in Micro-IDE and connect the terminal to the serial port that is connected to

MINI-MAX/51-C2. You should see the analog values of all 11 channels of DAQ-2543 board, including the thermocouple values.
