CS650 and CS655 Water Content Reflectometers
Drivers should be loaded before plugging the A200 into the PC.
The A200 drivers can be downloaded, at no charge, from:
www.campbellsci.com/downloads .
6.4.1.2 Cabling
One end of the A200 has a terminal block while the other end has a type B
female USB port. The terminal block provides 12V, G, TX, and RX terminals
for connecting the sensor (see FIGURE 6-2 and TABLE 6-2).
A data cable, part number 17648, ships with the A200. This cable has a USB
type-A male connector that attaches to a PC’s USB port, and a type B male
connector that attaches to the A200’s USB port.
6.4.1.3 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.
6.4.1.4 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 the Device Configuration Utility.
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 (e.g., LoggerNet) before and after the installation, or look in
the Windows Device Manager list under the ports section (access via the
control panel).
