8.7.2 Pass-Code Lockout
Pass-code lockouts (historically known in Campbell Scientific dataloggers simply
as "security codes") are the oldest method of securing a datalogger. Pass-code
lockouts can effectively lock out innocent tinkering and discourage wannabe
hackers on non-IP based comms links. However, any serious hacker with
physical access to the datalogger or to the comms hardware can, with only
minimal trouble, overcome the five-digit pass-codes. Systems adequately
secured with pass-code lockouts are probably limited to the following:
•
Private, non-IP radio networks
•
Direct links (hardwire RS-232, short-haul, multidrop, fiber optic)
•
Non-IP satellite
•
Land-line, non-IP based telephone, where the telephone number is not
published
•
Cellular phone wherein IP has been disabled, providing a strictly serial
connection
Up to three levels of lockout can be set. Valid pass codes are 1 through 65535 (0
confers no security).
Note Although a pass code can be set to a negative value, a positive
code must be entered to unlock the CR3000. That positive code will
equal 65536 + (negative security code). For example, a security code of -
1111 must be entered as 64425 to unlock the CR3000.
