7.8.2 Information Services
Support of information services (FTP, HTTP, XML, POP3, SMTP, Telnet,
NTCIP, NTP, HTML) is extensive in the CR800, to the point of requiring another
manual at least as thick as the CR800 manual so fully cover applicable topics.
This section only nicks the surface. The most up-to-date information on
implementing IS services is contained in CRBasic Editor Help.
Read More! Specific information concerning the use of digital-cellular modems
for information services can be found in Campbell Scientific manuals for those
modems.
When used in conjunction with a network-link interface that uses the CR800 IP
stack, or a cell modem with the PPP/IP key enabled, the CR800 has TCP/IP
functionality that enables capabilities discussed in this section:
Note For information on available TCP/IP/PPP devices, refer to the appendix
Network Links
(p. 545)
for model numbers. Detailed information on use of
TCP/IP/PPP devices is found in their respective manuals and CRBasic Editor
Help.
