Section 8. Operation through 3 are written, respectively. • external keyboard display settings • Device Configuration Utility (DevConfig) - Security passwords 1 through 3 are set on the Deployment tab. • SetSecurity() instruction - SetSecurity() is only executed at program compile time. It may be placed between the BeginProg and Scan() instructions. Note Deleting SetSecurity() from a CRBasic program is not equivalent to SetSecurity(0,0,0). Settings persist when a new program is downloaded that has no SetSecurity() instruction. 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 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 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 Security1 code is entered, read/write 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. • Level 3 - When this level is set, all communication with the datalogger is prohibited if no security code is entered. If Security3 code is entered, data can be viewed and collected from the datalogger (except data suppressed by the TableHide() instruction in the CRBasic program). If Security2 code is entered, data can be collected, public variables can be set, and the clock can be set. If Security1 code is entered, all functions are unrestricted. 8.11.2.1 Pass-Code Lockout By-Pass Pass-code lockouts can be bypassed at the datalogger using a external keyboard displaykeyboard display. Pressing and holding the Del key while powering up a CR6 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 telecommunication access without first correcting the security code. Note These features are not operable in CR1000KDs with serial numbers less than 1263. Contact Campbell Scientific for information on upgrading the CR1000KD operating system. 8.11.3 Passwords Passwords are used to secure IP based communications. They are set in various telecommunication schemes with the .csipasswd file, CRBasic PakBus instructions, CRBasic TCP/IP instructions, and in CR6 settings. 461
