Camera interfaces
Output signals
Output signals can be assigned to a variety of internal camera signals via soft-
ware. 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 5–24 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
/
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 envi-
ronmental electrical noise is inconsequential 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 V. 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 above events.
GPO
User programmable binary output.
