COM PORT VERIFICATION 

Installing the latest Firmware revision, as well as operating the 
ADXRS450 Evaluation GUI will require that the user know the 
communications port which has been assigned to the ISEB 
main board.  With the ISEB main board connected to the PC, 
the user should perform the following steps to determine the 
assigned COM port number: 
For Windows Vista: 

1.

 

From the start menu, right click on “Computer” and 
select “Properties” 
a.

 

This should open the window shown in  Figure 9 

2.

 

Underneath the “Tasks” heading, select “Device 
Manager” 
a.

 

Windows Vista may request that the user allow 
access to this panel, and Administrative privileges 
may be required. 

b.

 

The window shown in XYZ should now open 

3.

 

Expand the “Ports (COM & LTP)” menu item 
a.

 

The “ADI Inertial Sensor Evaluation System” 
should be listed with an assigned COM port 
number in parenthesis. 

4.

 

Note this value for future use 

 

Figure 5: Computer Properties 

 

Figure 6: Device Manager, showing the COM Port number 

For Windows XP/2000: 

1.

 

From the Start Menu, right click on “My Computer” 
and select “Properties”. 

2.

 

Click on the “Hardware” tab of the “System 
Properties” window as shown in Figure 11. 

3.

 

Select “Device Manager” to look-up the assigned 
COM port of the ISEB hardware 

a.

 

The Device Manager window should be 
similar to that presented in Figure 10
