Texas Instruments DAC12DL3200, Руководство пользователя, Страница: 7 / 32

3.1 Install the High Speed Data Converter (HSDC) Pro Software
Download the most recent version of the HSDC Pro software from www.ti.com/tool/dataconverterpro-sw . Follow
the installation instructions to install the software.
3.2 Install the Configuration GUI Software
1. Download the configuration graphical user interface (GUI) software from the EVM tool folder at http://
www.ti.com/tool/DAC12DL3200EVM .
2. Extract files from the compressed zip file.
3. Run the executable file (
setup.exe
), and follow the instructions.
3.3 Connect the DAC12DL3200EVM and TSW14DL3200EVM
With the power off, connect the DAC12DL3200EVM to the TSW14DL3200EVM through the FMC connector as
shown in
Figure 3-1 . Make sure that the standoffs provide the proper height for robust connector connections.
Ensure the board jumpers are configured as follows:
• JP1 (TXENB) pins 1–2. This enables the DAC outputs.
• JP2 (SLEEP) pins 2–3. This places the DAC out of sleep mode.
• JP3 (SYNC) No shunt. This input has an internal pullup. When high, the DAC uses the DxSTRB inputs for
strobe. When low, the DAC uses the data LSB as strobe. See the data sheet for more information.
• JP6 (LMX_CE) pins 1–2. This places the LMX in power down mode (board default).
• J6 (DAC NCO select) pins 1–2, 4–5, 7–8, 10–11, 13–14, 16–17. Default is all inputs tied to GND.
• J5, J7–J12 (FTDI Spare GPIOs) No shunt. Default is all inputs disconnected. These jumpers allow for FTDI to
control NCO select inputs when installed.
3.4 Connect the Power Supplies to the Boards (Power Off)
1. Confirm that the power switch on the TSW14DL3200EVM is in the off position. Connect the power cable to
a 12-V DC (minimum 3 A) power supply. Make sure of the proper supply polarity by confirming that the outer
surface of the barrel connector is GND and the inner portion of the connector is 12 V. Connect the power
cable to the EVM power connector.
2. Connect the power cable to a 5-V DC (minimum 4 A) power supply for the DAC12DL3200EVM. Make sure
of the proper supply polarity by confirming that the outer surface of the barrel connector is GND and the
inner portion of the connector is 5 V. Connect the power cable to the EVM power connector.
CAUTION
Make sure that the power connections to the EVMs are the correct polarity. Failure to do so may
result in immediate damage.
Make sure that the 12-V power supply is connected to the TSW14DL3200EVM and not the
DAC12DL3200EVM. Providing the DAC12DL3200EVM with 12-V may result in immediate
damage.
Leave the TSW14DL3200EVM power switch in the off position.
