Fig. 13: Typical Voltage Output Circuit
Figure 14 shows a typical circuit you can use to monitor the output line with an LED or an opto-
coupler. In this example, the voltage for the external circuit is +24 VDC. Current in the circuit is
limited by an external resistor.

By default, the camera’s exposure active (ExpAc) signal is assigned to output line 1. The exposure
active signal indicates when exposure is taking place.
The assignment of a camera output signal to the physical output line can be changed by the user.
For more information about output line pin assignments and pin numbering, see Section 5.2 on
page 24 .
For more information about the exposure active signal, see Section 6.8 on page 61 .
