Note the following precautions:
•
Since sending an OS resets CR3000 memory, data loss will certainly
occur. Depending on several factors, the CR3000 may also become
incapacitated for a time.
o
Is sending the OS necessary to correct a critical problem? If not,
consider waiting until a scheduled maintenance visit to the site.
o
Is the site conveniently accessible such that a site visit can be
undertaken to correct a problem of reset settings without excessive
expense?
o
If the OS must be sent, and the site is difficult or expensive to
access, try the OS download procedure on an identically
programmed, more conveniently located CR3000.
•
Campbell Scientific recommends upgrading operating systems only with
a direct-hardwire link. However, the Send Program
(p. 550)
button in the
datalogger support software allows the OS to be sent over all software
supported comms systems.
o
Operating systems are very large files — be cautious of line
charges.
o Updating the OS may reset CR3000 settings, even settings critical to
supporting the comms link. Newer operating systems minimize this
risk.
The operating system is updated with one of the following tools:
7.5.2.1.1 OS Update with DevConfig Send OS Tab
Using this method results in the CR3000 being restored to factory defaults. The
existing OS is over written as it is received. Failure to receive the complete new
OS will leave the CR3000 in an unstable state. Use this method only with a
direct hardwire serial connection.
How
Use the following procedure with DevConfig: Do not click Connect.
1. Select CR3000 from the list of devices at left
2. Select the appropriate communication port and baud rate at the bottom left
3. Click the Send OS tab located at the top of DevConfig window
4. Follow the on-screen OS Download Instructions
