Kos ... I understand perfectly what you're trying to convey in your choices.
#1 is saying it's the tdx's fault & #2 is saying it's the control board/program's fault ... but, in the case of choice #1, the tdx is simply a sending/receiving module, so it has little to factor in on the "reading" of the information being transmitted through it, since that's the job of the program. That would preclude choice #1 ... so #2 wins by default.
