This allows Windows Explorer to access the CR3000 file system via FTP, with drives on the CR3000 being mapped into directories or folders. The root directory on the CR3000 can be any drive. USR: is a drive created by the user-allocating memory to the USR: drive in the USRDriveSize field of the Status table or in the USR: Drive Size box on the Deployment | Advanced tab of the CR3000 service in DevConfig. Files on the CR3000 are contained on one of these directories. Files can be copied / pasted between drives. Files can be deleted through FTP. 7.8.2.5 FTP Client The CR3000 can act as an FTP Client to send a file or get a file from an FTP server, such as another datalogger or web camera. This is done using the CRBasic FTPClient() instruction. Refer to a manual for a Campbell Scientific network link (see the appendix Network Links (p. 569) ), available at www.campbellsci.com, or CRBasic Editor Help for details and sample programs. 7.8.2.6 Telnet Telnet is used to access the same commands that are available through the support software terminal emulator (p. 470). Start a Telnet session by opening a DOS command prompt and type in: Telnet xxx.xxx.xxx.xxx where xxx.xxx.xxx.xxx is the IP address of the network device connected to the CR3000. 7.8.2.7 SNMP Simple Network Management Protocol (SNMP) is a part of the IP suite used by NTCIP and RWIS for monitoring road conditions. The CR3000 supports SNMP when a network device is attached. 7.8.2.8 Ping Ping can be used to verify that the IP address for the network device connected to the CR3000 is reachable. To use the Ping tool, open a command prompt on a computer connected to the network and type in: ping xxx.xxx.xxx.xxx where xxx.xxx.xxx.xxx is the IP address of the network device connected to the CR3000. 176
