Output signals
Output signals can be assigned to a variety of internal camera signals via software.
They can be configured to active high or active low. The internal camera signals are
listed as follows:
Isolated Out Power
The Isolated Out Power connection provides power for isolated signals
Out 3
and
Out 4
. The voltage requirement is 5 to 24 VDC. The current requirement for this
supply is a function of the optical isolator collector current and the number of
outputs used in the system. Isolated Out Power wiring should be physically close to
Out 3
or
Out 4
wiring to prevent parasitic coupling.
Out 1 and 2 (Non-isolated)
Out 1
and
Out 2
signals are not electrically isolated and can be used when
environmental electrical noise is insignificant and faster trigger response is
required. Tie signal ground to Camera GND to complete the external circuit. The
output signal is a low voltage TTL, maximum 3.3 VDC. It is not suitable for driving
loads in excess of 50 µA.
Exposing
Corresponds to when camera is integrating light.
Trigger Ready
Indicates when the camera is ready to accept a trigger signal.
Trigger Input
A relay of the trigger input signal used to “daisy chain” the
trigger signal for multiple cameras.
Readout
Valid when camera is reading out data.
Imaging
Valid when camera is exposing or reading out.
Strobe
Programmable pulse based on one of the previously defined
events.
GPO
User programmable binary output.
