7.8.2.4 FTP Server
The CR800 automatically runs an FTP server. This allows Windows Explorer to
access the CR800 file system via FTP, with drives on the CR800 being mapped
into directories or folders. The root directory on the CR800 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 CR800 service in DevConfig. Files on the
CR800 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 CR800 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. 545)
), 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. 445).
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
CR800.
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 CR800 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 CR800 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
CR800.
