Hi.
NVR: DS-7208HQHI-K1
It works good for 1 year, but suddenly nvr stops working. When I power on:
I connected JST ZH via USB TTL cable to laptop, but in putty there is nothing response...
(Addition question: what is correct pins order in that example?)

Is it correct results?
Is it the end or can I do something elese?
Thx.
