Need some details about Tamper-detection

Question

Hi,

Based on this documentation page:
https://www.digi.com/resources/documentation/digidocs/90001548/#concept/trustfence/c_tamper_detection.htm

I couldn't find all responses to my questions.

Talking about opening the enclosure, is it the SOM enclosure or something else ?

The existing digital and analog interfaces use MCA pins. Does it mean that the tamper events detector pins are already connected to the encoluse of the SOM ?
Or need physically to connect them to the enclosure we want to protect ?

Any details about the Tamper-detection is welcome.

Thanks in advance for your answer.

Regards.

YC

>Talking about opening the enclosure, is it the SOM enclosure or something else ?

No, your enclosure - the enclosure you will put your product in. if you have this feature enabled and GPIO assigned to it, then the system will get notified if the enclosure is or was open via GPIO/interrupt

>The existing digital and analog interfaces use MCA pins. Does it mean that the tamper events detector pins are already connected to the encoluse of the SOM ?
See above - some does not have any enclosure. You build your product, create an enclosure and connect pins to it.

>Or need physically to connect them to the enclosure we want to protect ?
exactly!
