OPEC Open-Path Eddy-Covariance System CAUTION If you loan an IRGASON to a colleague, verify that the address is 1 before deploying the system into the field. 3.2 Loading a Program to the Datalogger Before the datalogger can begin to make measurements, a program must be transferred into its CPU. The program can be transferred using a PC and LoggerNet or using PC/CF cards. 3.2.1 Direct Connection via LoggerNet The datalogger program can be transferred to a datalogger using a PC, LoggerNet, and some sort of interface. In the eddy-covariance application, the most common interface is the RS-232 cable. TIP To avoid potential problems (mixed data and connectivity issues), configure LoggerNet with one station file per datalogger, even if the data is retrieved using cards and the computer is connected to multiple dataloggers for monitoring purposes only. See the LoggerNet manual Section 4.2. Set up a station in the LoggerNet network map; see Section 4.1 in the LoggerNet manual for details. To transfer a program to the datalogger, start LoggerNet. Click on the "Connect" button in the Toolbar. Select the station and click on the "Connect" button. Check the datalogger time, it is located in the upper right hand side of the Connect Screen. If the datalogger and PC time differ by more than a few seconds, set the datalogger time by clicking on the "Set Station's Clock" button. To download a program, click on the "Send" button. Navigate to the folder where the program is saved, select it, and click on "OK". 3.2.2 Remote via PC/CF Card The datalogger program can be transferred to a datalogger using a PC/CF card. The CRBasic dataloggers reserve 10% or 80 Kbytes of space, whichever is smaller, on cards to store programs. Copy the program onto the card using Windows Explorer. CAUTION Use only PC/CF Cards sold by Campbell Scientific Inc. Although consumer versions of PC/CF cards will fit into the card slot and operate, only the PC/CF cards carried by Campbell Scientific have passed our temperature and electrostatic discharge (ESD) testing. The following instructions assume a basic familiarity in the operation of a CRBasic datalogger keyboard; see the datalogger manual for details on using the keyboard. Insert the card into the datalogger card slot. Press the key. If necessary, select the "System Menu" menu and press the key. Select the "File" menu and press the key. Select the "Copy" menu and press the key. The cursor should be at the "From" line. Press the 9
