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
3.11. External power supply input (AUX)
Item Parameter/note
Supported voltage range 4.5-5.5V
Typical input current* 0.65A, @5V while acquiring
Maximum input current* 0.67A, @5V
Protection Over/under voltage protection
* Is model depended. Used values are for MC124MG-SY-TC
