7.5.2 Outputs
The camera has 2 non-inverting outputs with open emitters. These are shown in the following
diagram:
Max. emitter current 500 mA
Max. collector emitter voltage 45 V
 Voltage above +45 V may damage the optical coupler
 Depending on the voltage applied at OutVCC, it may be necessary to switch a resistor in
series between Gpoutl and ground.
Figure 21: Output schematics
Output features are configured by software. Any signal can be placed on any output.
The main features of output signals are described below:
IntEna Signal
This signal displays the time in which exposure was made. By using a register this output can be
delayed by up to 1.05 seconds.
Fval Signal
This feature signals readout from the sensor. This signal Fval follows IntEna.
Busy Signal
This indicator appears when the exposure is being made; the sensor is being read from or data
transmission is active. The camera is busy.
