-//picture//+==== Thermocouple Connectors ==== 
 + 
 +Each of the four(4) channels uses an Omega style connector for the thermocouples, which makes it easier to plug in and out different thermocouple types.  Type U was selected so that all the channels on the board (P1 - P4) would be universal and interchangeable.   
 + 
 +There is an RTD beneath the copper tabs of each connector which is used to measure the cold junction temperature.  So no external cold junction measurement is needed with this board. 
 + 
 +==== Chip Select ==== 
 + 
 +The chip select header (JP1) is used to select the chip select pin on the AD7124.  This allows for flexibility on the SPI bus when stacking multiple Arduino shields together.  To change the chip select of the AD7124, all you need to do is move the shunt to one of the below locations, and then make the corresponding change in software. 
 +^ Jumper Position (JP1) ^ AD7124 Chip Select Pin (P8)^ 
 +| Across Pin 1 and 2 | Pin 3 | 
 +| Across Pin 3 and 4 | Pin 2 | 
 +| Across Pin 5 and 6 | Pin 1 | 
 + 
 +To use the EVAL-CN0391-ARDZ with the software we provide, please connect the thermocouples to each channel and set the software to corresponding thermocouple type/channel . Please set the default jumper position as pictured:

-===== Chip Select ===== +===== Digital Communications ===== 
-    + 
-====== Schematic, PCB Layout, Bill of Materials ======+The AD7124 Analog to Digital converter, measures each sensor input channel on the board.  The results are then sent over to the processor via the SPI communications protocol.  More reading about SPI Communications can be found [[wp>Serial_Peripheral_Interface_Bus|here.]] 
 + 
 +The SPI digital communications lines can be found on two(2) connectors on the EVAL-CN0391-ARDZ. 
 +P8 and P7 have the SPI lines to handle the communication between the AD7124 and the processor. 
 + 
 +==== SPI Connectors (P8 & P7) ==== 
 + 
 +^ P8 Connector Pins ^ SPI Function ^ 
 +| Pin 1,2, or 3 | SPI_CS | 
 +| Pin 4 | SPI_MOSI | 
 +| Pin 5 | SPI_MISO | 
 +| Pin 6 | SPI_CLK | 
 + 
 +^ P7 Connector Pins ^ SPI Function ^ 
 +| Pin 1 | SPI_MISO | 
 +| Pin 3 | SPI_CLK | 
 +| Pin 4 | SPI_MOSI | 
 +<note> If using SPI from **P7** connector, the Chip Select **must** come from the P8 connector. </note>
