Synchronisation Output
The synchronisation output gives out a TTL signal synchronous to the
frame rate of the camera. The positive edge is synchronous to the
beginning of the exposure time of each frame.
Output Impedance: 50 Ohm.
Signal Level: approx. 4 Volt into high impedance (> 500Ohm)
approx. 2 Volt into 50 Ohm
Example for high impedance termination:
