How effective are pass-code lockouts for CRBasic PakBus data loggers?

Pass-code lockouts (historically known as security codes) are the oldest method of securing a Campbell Scientific data logger. This method provides a level of security, mainly for PakBus communications. However, someone with physical access to a data logger or telecommunications hardware may be able to overcome the five-digit pass-code lockouts. To further secure PakBus communications, use the PakBus Encryption Key and PakBus/TCP password.
