Tamper-detection interfaces

There are up to four tamper detection interfaces. Each interface has its own independent configuration for all parameters (such as in/out pins, power off delay, active levels). Interfaces 0 and 1 can only be configured as digital detection and interfaces 2 and 3 can only be configured as analog detection.

Digi does not recommend that you configure two or more tamper interfaces on the same pin (i.e. two interfaces have the same input or output pin). Doing so can lead to unexpected behavior and Linux driver errors when loading.
