Table 1 Power Cable Pins Definitions
3.2 Exposure Output
The camera outputs a TTL exposure control signal from the SMA socket on the camera rear plate to
customer optical system. The exposure cable could be a 26 AWG coax cable which one end with SMA for
camera side and another end will select a connector which mates to the shutter device. The exposure coax
cable center pin is signal and the shield case is GND. When exposure signal is TTL high, the camera is in
exposure. When exposure signal is TTL low, the camera should be in dark and send one frame image data
via camera link cable.

3.3 External Trigger Input
The QuantaPro camera has three statuses. See Figure 4. At the pink area, the camera sensor is no charge
transfer in pixels. The green area is exposure time there is no pixel charge transfer too. The yellow area is
image read out time the all pixels charge will transfer to output. During the charge transfer time, the
camera should be in dark with no illumination in any wavelength light.
The frame trigger signal is the starter for grabbing an image. In different trigger mode, the frame trigger
signal is come from different source. The frame trigger signal is rise edge active.
When cameras run at external trigger mode, the camera needs a TTL frame trigger signal from the system.
The system can control the camera exposure start at a time point. The Frame Trigger signal rising edge to
exposure signal rising edge delay tolerance accuracy is less then 1 µs. The delay ‘B’ in Figure 4 is
considered the fixed system response delay. The Exsync coax cable is end with SMA connector to the
camera side which similar with the exposure cable and another end should mate to the system external
trigger output device. The external trigger signal can also get from the Camera link CC1.
