TTL / Logic
The TTL/Logic connection permit connection to other devices for synchronisation and control of fire, trigger and shutter
operations. Connector type: SMA, provided with SMA - BNC cable Fire (Output), External Trigger (Input), Shutter
(Output). These are used to send or receive Triggering and Firing signals. The SMA outputs (Fire & Shutter) are CMOS
compatible & Series terminated at source (i.e. in the camera head) for 50Ω cable.
NOTE: The termination at the customer end should be high impedance (not 50Ω) as an incorrect impedance match
could cause errors with timing and triggering. The SMA Ext Trig input is TTL level & CMOS compatible and has 470Ω
impedance.
