 HARDWARE CONFIGURATION 

To configure the hardware, follow these steps: 
1.

 

If not already connected, plug the USB A to Mini-B cable 
into the PC.  

2.

 

Connect the ISEB to the USB cable.  
If prompted to install the device, see the Software 
Configuration s
ection for details on how to install and 
select the correct driver. 

3.

 

Ensure that the jumpers on the ADXRS450 satellite are in 
their default configuration, as shown in Figure 9.  This will 
setup the board to use the on-board boost converter to 
generate the device’s required high voltage supply.  For 
more information on using alternate high voltage supplies, 
refer to the ADXRS450 datasheet as well as the Alternate 
External High Voltage Supply s
ection of this document.

4.

 

Connect the ISEB to the ADXRS450 satellite using the  
18-inch, 20-pin ribbon cable. This cable is keyed to prevent 
inserting it backwards and causing damage to the system.  

5.

 

Connect theThe inertial sensor evaluation system should now be set up and 
ready to use, and should resemble the setup shown in
 Figure 9.
