Campbell Scientific CR3000 Micrologger - Manual (Page 73)

Section 5. System Overview
73
Level 1 must be set before Level 2. Level 2 must be set before Level 3. If a level
is set to 0, any level greater than it will also be set to 0. For example, if level 2 is
0 then level 3 is automatically set to 0. Levels are unlocked in reverse order: level
3 before level 2, level 2 before level 1. When a level is unlocked, any level
greater than it will also be unlocked, so unlocking level 1 (entering the Level 1
security code) also unlocks levels 2 and 3.
Functions affected by setting each level of security are:
• Level 1 — Collecting data, setting the clock, and setting variables in the
Public table are unrestricted, requiring no security code. If the user enters the
Security1 code non-read-only values in the Status table can be changed and
the datalogger program can be changed or retrieved.
• Level 2 — Data collection is unrestricted, requiring no security code. If the
user enters the Security2 code, the datalogger clock can be changed and
variables in the Public table can be changed. If the user enters the Security1
code, non-read-only values in the Status table can be changed and the
datalogger program can be changed or retrieved.
• Level 3 — When this level is set, all communication with the datalogger is
prohibited if no security code is entered. If the user enters the Security3 code,
data can be viewed and collected from the datalogger (except data suppressed
by the TableHide() instruction in the CRBasic program). If the user enters
the Security2 code, data can be collected, public variables can be set, and the
clock can be set. If the user enters the Security1 code, all functions are
unrestricted.
5.1.9.2.1 Security By-Pass
Security can be bypassed at the datalogger using a integrated keyboard /
displaykeyboard display. Pressing and holding the "Del" key while powering up a
CR3000 will cause it to abort loading a program and provide a 120 second
window to begin changing or disabling security codes in the settings editor (not
Status table) with the keyboard display.
Keyboard display security bypass does not allow telecommunications access
without first correcting the security code.
Note This feature is not operable in CR1000KDs with serial numbers less than
1263. Contact Campbell Scientific for information on upgrading the CR1000KD
operating system.
5.1.9.3 Passwords
Passwords are used to secure IP based communications. They are set in various
telecommunications schemes via the .csipasswd file, CRBasic PakBus
instructions, CRBasic IS instructions, and in CR3000 settings.
5.1.9.3.1 .csipasswd
The .csipasswd file is a file created and edited through DevConfig, and which
resides on the CPU: drive of the CR3000. It contains credentials (usernames and
passwords) required to access datalogger functions over IP telecommunications.
See Web API
for details concerning the .csipasswd file.
