The ADT7470 monitors the temperature of the TMP05s. Up to six more TMP05s can be connected to the board in a daisy-chain fashion via the J15 connector. The ADT7470 also controls the fan speed of both on-board fans. There is provision for control of two more fans that can be easily connected to the board via the J10 connector and J14 connector. This data sheet concentrates on the on-board TMP05s and fans only. There are various test points around the board for ease of evaluation. The evaluation board also has a USB section. This allows the PC software to communicate with the evaluation board through the USB port of the PC. Users can easily change register settings on the ADT7470 this way and monitor the status registers. The software uses this interface to plot the graphs seen in the graphing section of the software. USB INTERFACE CONNECTOR J27 The connections to J27 are shown in Table 1. Table 1. J27 Connections J1 Pin 1 2 3 4 ADT7470 Function 5V SCL SDA GROUND GETTING STARTED Do not connect the USB cable to the evaluation board until the software is installed. To get started: 1. Install the ADT7470 software. (If installed already, skip this step). 2. Connect the evaluation board to the USB port on the computer, using the USB interface cable provided. 3. Run the software from the Windows Start menu. 4. Connect a 12 V dc supply to J17 or J18. 5. For temperature monitoring of the TMP05s, ensure that Jumper J19 is in Position B. The evaluation board is now ready to use. Everything is controlled by the software; it is recommended to use the software for changing settings and monitoring their effects on the system. EVALUATION The ADT7470 performs many temperature sensing and fan control functions. The evaluation board allows users to simulate various faults that could affect the ADT7470 in a working system. Users can monitor how the ADT7470 handles these events in many ways. See the Evaluation Board Software section for a description of the software. The board’s Alert LED can also show certain fault conditions. Rev.

The InstallShield Wizard dialog box will then appear. • Follow the on-screen instructions to complete the installation. USING THE SOFTWARE When using the software, first ensure that the evaluation board is connected to the PC. To start the software, click Start/ Programs/Analog Devices/ADT7470 Evaluation Software. The loading dialog box in Figure 2 will then appear. If the board is not plugged in, the user will get an error message, and the software will not start. To use the software immediately, the user must select the Yes option to restart his or her PCs so that Windows can update the setup files. If the user does not wish to use the software immediately, he or she must select the No option. No matter which option is selected, the user must click Finish to complete the installation. Rev. A | Page 4 of 16 06209-002 The software allows the ADT7470's functions to be controlled from the PC via an easy to use interface operating under the Windows environment. The contents of the device's internal registers can easily be read or altered through a user-friendly graphical interface. Figure 2. Software Loading Dialog Box Evaluation Board Data Sheet EVAL-ADT7470EB ADT7470 EVALUATION SOFTWARE DIALOG BOX 06209-003 The ADT7470 Evaluation Software dialog box (see Figure 3) controls the settings for the ADT7470 and allows the user to communicate easily with the evaluation board. By using the pull down menus and toolbar icons, the user can access the various settings and readings. The associated dialog box will appear as a subbox in the ADT7470 Evaluation Software dialog box. Figure 3. ADT7470 Evaluation Software Dialog Box Rev. A | Page 5 of 16 EVAL-ADT7470EB Evaluation Board Data Sheet Click View/Graphing in the ADT7470 Evaluation Software dialog box. A dialog box will appear that shows a real-time graph of the temperature of the four TMP05s as well as a graph of the fan speed of both fans (see Figure 4). The graph can be resized by grabbing and dragging the tabs on the y-axis of the graphs. A change in any of the TMP05s or the fans will be seen here. Click the Configuration/General Configuration in the ADT7470 Evaluation Software dialog box. The Configuration dialog box will appear (see Figure 5), which shows some general configuration items. Note that it is necessary to change the Pin13 Setup to TMP05 Start Output to ensure that the ADT7470 monitors the TMP05s on the board. Figure 4. Graphing Dialog Box CHANGING THE TEMPERATURE OF A TMP05 Two heating elements are built-in to the board, which allows users to heat up either TMP05 No. 1 or TMP05 No. 2. The software can be used to perform this. Click Board/On Board Heater Control in the ADT7470 Evaluation Software dialog box (or click the Heater Control icon). This opens a simple interface that allows users to heat up a resistor on the evaluation board. Figure 6 shows a screen shot of the Heater Control dialog box and the Graphing dialog box. As is shown in Figure 6, TMP05 No. 1 was heated up because of the on-board heater. If automatic fan speed control is enabled, Fan No. 1 will increase its speed to try to compensate for the increased temperature. Rev.

Heater Control and Graphing Dialog Boxes TEMPERATURE AND FAN SPEED LIMITS AND INTERRUPTS 06209-007 Click View/Limits and Interrupts in the ADT7470 Evaluation Software dialog box. The Limits and Interrupts dialog box will then appear and display a slider bar for the temperature and fan speed limits. Users can click the drop-down box to set each of the temperature and fan speeds. If any limits are exceeded, the associated Interrupts icon on the left side of the dialog box will turn from green to orange. In Figure 7, Fan 2 has exceeded one of its limits, so its Interrupts is orange. To mask (ignore) this interrupt flag, the user should click the Mask button associated with the interrupt. When an interrupt is set, the red Alert LED on the evaluation board is also set. If the error condition is removed, it will turn off. Figure 7. Limits and Interrupts Dialog Box Rev. A | Page 7 of 16 EVAL-ADT7470EB Evaluation Board Data Sheet FAN CONFIGURATION Another alternative to the software programming mentioned so far is to program the bits in each register individually. This is where the Register Map dialog box can be used. Click View/ Register Map in the ADT7470 Evaluation Software dialog box to access this (see Figure 8). Users can choose an individual register by expanding the tree and by clicking on the appropriate register. The contents of the register can be changed in two ways. Users can click the bit in the bit display or type in a Hex or Dec value and write to the register. Note that it is not possible to write a new value to a read-only register. Users should crossreference the ADT7470 data sheet when using the Register Map dialog box because it contains additional information and a description of the bit functions. In general, users should not use this dialog box unless they are very familiar with this part. Another way to set up the fans is to open the Fan Configuration dialog box. Click Configuration/Fan Configuration in the ADT7470 Evaluation Software dialog box (see Figure 9). In this dialog box, users can configure each fan, individually or collectively, by clicking on the appropriate tab. 06209-009 REGISTER TREE/REGISTER MAP Figure 9. Fan Configuration Dialog Box 06209-008 SAVING THE SETUP Figure 8. Register Map Dialog Box To save the settings of the ADT7470 software, click File/Save/Recall Configuration in the ADT7470 Evaluation Software dialog box. This allows users to save the contents of the registers and the current evaluation board setup to a file. This file can be shared with a colleague, customer, or vendor to help recreate the desired setup. To open an existing file, click File/Save/Recall Configuration in the ADT7470 Evaluation Software dialog box and choose the appropriate data file. Rev.
