Instruction manual

CS650 and CS655 Water Content Reflectometers
and programming examples for Edlog dataloggers are provided at
www.campbellsci.com\old-manuals.
The SDI12Recorder() measurement instruction programs CRBasic
dataloggers (CR6, CR200(X)-series, CR800-series, CR1000, CR3000, and
CR5000) to measure the sensor. This instruction sends a request to the sensor
to make a measurement and then retrieves the measurement from the sensor.
See Section 8.2, SDI-12 Measurements
(p. 19), for more information.
When using a CR200(X), the SDI12Recorder() instruction has the following
syntax:
SDI12Recorder(Destination,OutString,Multiplier,Offset)
For the other CRBasic dataloggers, the SDI12Recorder() instruction has the
following syntax:
SDI12Recorder(Destination, SDIPort, SDIAddress, “SDICommand”,
Multiplier, Offset)
8. Operation
8.1 A200 and Device Configuration Utility
The A200 Sensor-to-PC Interface allows communication between a CS650 and
a PC, allowing sensor settings to be changed through Device Configuration
Utility (DevConfig) software.
8.1.1 Using the A200
8.1.1.1 Driver Installation
If the A200 has not been previously plugged into your PC and your PC
operating system is not Windows 7, the A200 driver needs to be loaded onto
your PC.
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.
8.1.1.2 RS-232 Wiring
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 8-1 and TABLE 8-1).
