   * Use the FMC-SDP interposer to connect the ADI evaluation board to the Xilinx KC705 board on the FMC LPC connector.
   * Connect the JTAG and UART cables to the KC705 and power up the FPGA board.
-  * Start IMPACT, and double click “//Boundary Scan//”. Right click and select //Initialize Chain//. The program should recognize the Kintex 7 device (see screenshot below).
-{{ :resources:fpga:xilinx:interposer:impact_config.png?300 }}
-  * Program the KC705 FPGA using the "//Bit/download.bit//" file provided in the reference design archive.
-  * Power the ADI evaluation board.
-At this point everything is set up and it is possible to start the evaluation of the ADI hardware through the controls in the uC-Probe application provided in the reference design.
-===== Configure uC-Probe =====
-Launch **uC-Probe** from the **//Start -> All Programs -> Micrium -> uC-Probe//**.
-Select **uC-Probe** options.
-  * Click on the **uC-Probe** icon on the top left portion of the screen.
-  * Click on the **//Options//** button to open the dialog box.
-{{ :resources:fpga:altera:bemicro:ucprobeoptionsbtn.png?300 }}
-Set target board communication protocol as **//RS-232//**
-  * Click on the **//Communication//** tab icon on the top left portion of the dialog box
-  * Select the **//RS-232//** option.
-{{ :resources:fpga:xilinx:interposer:ucprobe_comm.png?300 }}
-Setup **//RS-232//** communication settings
-  * Select the **//RS-232//** option from the **//Communication//** tab.
-  * Select the COM port to which the KC705 board is connected.
-  * Set the Baud Rate to 115200 bps.
-{{ :resources:fpga:xilinx:interposer:ucprobe_rs232.png?300 }}
-  * Press **//Apply//** and **//OK//** to exit the options menu.
-===== Load and Run the Demonstration Project =====
-  * Click the **//Open//** option from the **uC-Probe** menu and select the file **//ucProbeInterface/AD5694R_Interface.wsp//** provided within the reference design files.
-  * Before opening the interface **uC-Probe** will ask for a symbols file that must be associated with the interface. Select the file **//ucProbeInterface/ADIEvalBoard.elf//** to be loaded as a symbol file.
-  * Run the demonstration project by pressing the **//Play//** button.
-{{ :resources:fpga:altera:bemicro:image081.png?200 }}
-<WRAP tip>In some cases it is possible that the uC-Probe interface will not respond to the commands the first time it is ran. In this situation just stop the interface by pressing the **//Stop//** button and run it again by pressing the **//Play//** button.</WRAP>
-===== Demonstration Project User Interface =====
-The following figure presents the **uC-Probe** interface that can be used for monitoring and controlling the operation of the **EVAL-AD5694RSDZ** evaluation board.
-{{ :resources:fpga:altera:bemicro:ad5694r_interface.png?700 }}
-**Section A** is used to activate the board and monitor activity. The communication with the board is activated / deactivated by toggling the //ON/OFF// switch. The //Activity// LED turns green when the communication is active. If the //ON/OFF// switch is set to //ON// and the //Activity// LED is //BLACK// it means that there is a communication problem with the board. See the **Troubleshooting** section for indications on how to fix the communication problems.
-**Section B** is used to select the //Command// to be sent to the DAC. The definition of each command is available in Table 7 of the part's datasheet.
-**Section C** is used to select the //Address// of the registers to be affected by the command, if the command is 1, 2 or 3. If the selected command is 5, the //Address// buttons will be used to program the //LDAK MASK REGISTER// for the corresponding DAC. For the other commands, they are ignored.
-**Section D** is used to program the value to be written to the DAC registers.
-**Section E** is used to send the selected command to the DAC.
-**Section F** is used to configure the databits sent for the command 4. Each DAC's power operation can be configured independently.
+<WRAP round important 80%>
+\\
+To power on the EVAL-AD5694R evaluation board, you need to apply +6V supply voltage to J3 connector of the board.
+</WRAP>
-**Section G** is used to configure the databits sent for the command 7. If the button is pressed, the Internal reference will be turned off.

-In case there is a communication problem with the board the follwing actions can be perfomed in order to try to fix the issues:
+===== Software Project Setup =====
-  * Check that the evaluation board is powered as instructed in the board's user guide.
+{{page>import_workspace}}
-  * In uC-Probe refresh the symbols file by right-clicking on the **//System Browser//** window and selecting **//Refresh Symbols//**.
-  * If the communication problem persists even after performing the previous steps, restart the uC-Probe application and try to run the interface again.
