8.1.1.3 Powering the Sensor
The A200 provides power to the sensor when it is connected to a PC’s USB port.
An internal DC/DC converter boosts the 5 Vdc supply from the USB connection
to a 12 Vdc output that is required to power the sensor.
8.1.1.4 Determining which COM Port the A200 has been Assigned
When the A200 driver is loaded, the A200 is assigned a COM port number. This
COM port number is needed when using
DevConfig . Often, the assigned COM
port will be the next port number that is free. However, if other devices have been
installed in the past (some of which may no longer be plugged in), the A200 may
be assigned a higher COM port number.
To check which COM port has been assigned to the A200, you can monitor the
appearance of a new COM port in the list of COM ports offered in your software
package such as
LoggerNet before and after the installation, or look in the
Windows Device Manager list under the ports section (access via the control
panel).
8.1.2 Device Configuration Utility ( DevConfig )
DevConfig may be downloaded from the Campbell Scientific website,
www.campbellsci.com/downloads .
Connect the CS650 to the A200 as shown in Table 8-1 . Connect the PC to the
A200 USB port with the supplied USB cable.
Launch DevConfig and select CS650 Series from the Device Type menu on the
left. Select 9600 from the Baud Rate drop-down menu.
