13 / 26 page  13 dc2023afa DEMO MANUAL DC2023A setup proceDure for multi-BoarD arrays Procedure: 1. Stack the boards side-by-side by plugging JP1 of one board into JP2 of another DC2023A board. 2. Ensure different slave address settings for each of the boards. The address of each board is set by the DIP switch JP3 on the backside of the board. The setting must be unique for each board in the array. 3. Plug in the +12V VIN power into one of the boards as shown in Figure 12. Only one +12V power source is allowed. 4. The USB to I2C/SMBus/PMBus Controller may be plugged into any board. If no LTM2987s show up in the GUI, click the hourglass icon to enumerate the I2C bus and find the addresses of the parts. Go to step 2 to ensure that each board has a unique DIP switch setting. 5. Since the individual CONTROL lines are connected across the boards (CTRL is a common signal across all boards in the array), make sure that all CONTROL switches are set to the RUN position. 6. Relaunch LTpowerPlay. It will enumerate the entire board array and build a representative system tree and read all hardware settings into the GUI. Attention: Once the GUI has launched, click the “RAM->NVM”buttoninthetoolbartoensurethattheslave addressesareretainedafterapowerofforreset. Otherwise you may lose communication with the slaves after a power cycle or reset event. Figure 12. Array of Multiple DC2023A Demo Boards |
