A CRBasic program directs the CR800 how and when sensors are to be measured,
calculations made, and data stored. A program is created on a PC and sent to the
CR800. The CR800 can store a number of programs in memory, but only one
program is active at a given time. Two Campbell Scientific software applications,
Short Cut and CRBasic Editor, are used to create CR800 programs.
• Short Cut creates a datalogger program and wiring diagram in four easy
steps. It supports most sensors sold by Campbell Scientific and is
recommended for creating simple programs to measure sensors and store
data.
• Programs generated by Short Cut are easily imported into CRBasic
Editor for additional editing. For complex applications, experienced
programmers often create essential measurement and data storage code
with Short Cut, then add more complex code with CRBasic Editor.
Note Once a Short Cut generated program has been edited with
CRBasic Editor, it can no longer be modified with Short Cut.
5.8 Security — Overview
The CR800 is supplied void of active security measures. By default, RS-232,
Telnet, FTP and HTTP services, all of which give high level access to CR800 data
and CRBasic programs, are enabled without password protection.
You may wish to secure your CR800 from mistakes or tampering. The following
may be reasons to concern yourself with datalogger security:
• Collection of sensitive data
• Operation of critical systems
• Networks accessible by many individuals
If you are concerned about security, especially TCP/IP threats, you should send
the latest operating system to the CR800, disable un-used services, and secure
those that are used. Security actions to take may include the following:
• Set passcode lockouts
• Set PakBus/TCP password
• Set FTP username and password
