Section 5. System Overview 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 5.1.9.3.1 .csipasswd 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. 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. 73
