PakBus encryption, new to OS 26 and LoggerNet 4.2, is end-to-end encryption of PakBus payloads such as control commands and data. This AES-128 encryption with a shared password is compatible with communication between LoggerNet and the CR1000, CR3000, CR800, and CR850 dataloggers. A PakBus Encryption Key must be entered in both the datalogger’s device settings and in the LoggerNet Setup screen. Datalogger-to-datalogger communication can also be encrypted. When using PakBus encryption, a datalogger will not accept unencrypted commands from another device unless the device has been included in an EncryptExempt() CRBasic instruction.
