8.1.1.3 Powering the sensor
The A200 provides power to the sensor when it is connected to a computer 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 installed, the A200 is assigned a COM port number. This COM port
number is needed when using
Device Configuration Utility . Often, the assigned COM port is the
next port number that is free. However, if other devices were previously installed (some of which
may not be plugged in), the A200 may be assigned a higher COM port number.
To check which COM port has been assigned to the A200, 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
The Device Configuration Utility is available as a download on www.campbellsci.com/downloads .
It is included in installations of LoggerNet , RTDAQ , or PC400 .
Connect the CS650 to the A200 as shown in Table 8-1 (p. 14). Connect the computer to the A200
USB port with the supplied USB cable.
Launch Device Configuration Utility and search for CS650 Series from the Device Type list on the
