I/O Specification
Digital IO interfaces
Digital IO’s of the GigEPRO camera are electrically decoupled by optocoupler to prevent damage or
unwanted interference by ground loops or block voltage spikes. An optocoupler is a device using optical
path to transfer an electronic signal between two circuits. It consists of a photodiode converting the
input signal to light and a phototransistor converting the light again to electronic signal. GigEPRO
cameras provide 1 digital input and 2 digital output that way.
Digital Data Input
The digital input (Line0) can be used for trigger applications or other synchronization tasks for GigEPRO
cameras. An external signal level from 0~0.5V is interpreted as
Low
, a level from 3.3~24V is interpreted
as
High
. The input voltage must not exceed the 24 V limit.
