Anleitung Zusammenfassung
The system consists of the inertial sensor evaluation board (ISEB), or main board, and a satellite board for any Analog Devices inertial sensor product. The ISEB connects directly to a PC via its USB, where the USB connection provides both power and communications to the board. The ISEB then connects to the satellite board through a ribbon cable. This cable allows the satellite to be easily manipulated for testing or for being separately placed into an environmental chamber for temperature or humidity testing. Separating the boards mitigates corruption of data due to the temperature and humidity effects of other components. The ISEB is a universal main board and is intended to be used with various satellites of Analog Devices inertial sensors, including analog and digital accelerometers, as well as gyroscopes. The different products are evaluated by means of separate GUIs that are customized for performance and characterization measurements relevant to the inertial sensor being evaluated. The EVAL-ADXL345Z-M system contains the ISEB and the EVAL-ADXL345Z-S satellite. Also included is a USB A to Mini-B cable to connect the ISEB to a PC and an 18-inch, 20-pin ribbon cable to connect the ISEB to the satellite. A CD is also included with the necessary drivers and executables to use the system and to quickly begin evaluating the ADXL345.

These are available in the /Drivers/ folder on the packaged CD. Installing the USB Drivers for the ISEB To install the USB drivers, follow these steps. 1. Execute the ADI_ISEB_USB_Drivers.exe file located in /Drivers/ISEB_USB/. 2. Follow the on-screen instructions to install the drivers. 3. Click Continue Anyway when prompted that the drivers are not tested. It may be necessary to manually select the correct drivers after installation. To select the drivers, follow these steps. 1. Connect the USB A to Mini-B cable to the PC and then to the ISEB. The satellite board does not need to be connected for this step. New hardware is detected upon completion of this step. 2. If prompted to install drivers again, click Install from a list or specific location (Advanced), see Figure 2. Adobe Systems 08119- 002 Figure 2. Found New Hardware Prompt 3. Select Don’t search. I will choose the driver to install. (see Figure 3) and select ADI Inertial Sensor Evaluation System from the model list (see Figure 4). The ISEB should be detected automatically in the Device Manager as the ADI Inertial Sensor Evaluation System under the Ports (COM & LPT) selection. It is recommended to open the Device Manager to verify hardware detection and to record the communication port associated with the ISEB for use in the GUI. Adobe Systems 08119- 003 Figure 3.

To ensure that the drivers are installed properly, it is recommended that you reboot when prompted. 1. Execute the LVRTE851std.exe file located in the /Drivers/ folder. 2. Follow the on-screen instructions to complete installation of the LabVIEW run-time engine. 3. Reboot the PC. 4.
