3.10.5. Non-isolated Digital Lines (-UB and -TC only)
Non isolated Digital lines can be used as inputs or outputs compatible with TTL logic. These are high impedance pins so when
used as output high impedance slave input has to be used.

NOTE 1) Because of low input impedance of non-isolated input it is not possible to connect master slave of two cameras
directly. Signal conditioning (buffer, opamp…) is required
