NL120 Ethernet Module In order to use FTP, the datalogger's FTP User Name and FTP Password must be set. This is done using Device Configuration Utility. 6.3.1.1 Step 1 - Configure Datalogger a. Connect serial cable from PC COM port to datalogger RS-232 port. b. Open Campbell Scientific's Device Configuration Utility. Select the device type of the datalogger (CR1000 or CR3000), the appropriate Serial Port, and baud rate. Connect to the datalogger. c. Under the Net Services tab, verify that FTP Enabled is checked. Input the FTP User Name and FTP Password. d. Press the Apply button to save the changes and then close the Device Configuration Utility. NOTE Using "anonymous" as the user name with no password allows FTP access without inputting a user name or password. 6.3.1.2 Step 2 - Access File System a. Datalogger must be set up for Ethernet communications as explained in Sections 4.1, Physical Set-up, and 4.2, Communicating via Ethernet (Step 1 only). b. Open a Windows Explorer window. Enter ftp://username:[email protected] where nnn.nnn.nnn.nnn is the IP address of the datalogger. NOTE If the user name is "anonymous" with no password, enter ftp://nnn.nnn.nnn.nnn where nnn.nnn.nnn.nnn is the IP address of the datalogger. 6.3.2 FTP Client The datalogger can also act as an FTP Client to send a file to or get a file from an FTP Server (for example, another datalogger or web camera). This is done using the FTPClient() instruction. The following program is an example of using FTPClient() to send a file to another datalogger and get a file from that datalogger. The first parameter in the instruction is the FTP Server's IP address. The second parameter is the FTP username. The third parameter is the FTP password. The fourth parameter is the local filename. The fifth parameter is the remote file name. The final parameter is the put/get option: 0 for put and 1 for get. The instruction returns -1 if the instruction was successful and 0 if it was not. 10
