Using the Outputs with LVTTL
You can use a camera output line as an input to a low voltage TTL receiver, but only if the camera’s
output signal is used as shown in Figure 26. In this situation, a low will be indicated by a camera
output voltage near zero, and a high will be indicated by a camera output voltage of approximately
3.3 VDC. These voltages are within the typically specified levels for low voltage TTL devices.
For the camera’s I/O circuitry to operate properly, you must supply a ground as shown in Figure 26.

7.7.2.2 Input Related Signals as Output Signals
The camera allows selecting the output signals of the shaft encoder module or of the frequency
converter module and assigning them to one of the camera’s digital output lines. In this fashion input
signals can be passed through a camera to trigger additional cameras.
To ensure that even very narrow signals, e.g. signals from a shaft encoder, will reliably be
transmitted to other cameras the MinOutPulseWidthAbs parameter allows setting signals to a
minimum width (in microseconds).
