Isolated IN GND
The Isolated IN GND connection provides the user ground reference and return
path for
In 2
. It is recommended that the ground wiring be physically close to the
In2
wiring to prevent parasitic coupling. For example, a good cable design connects
In 2
to one conductor of a twisted pair, Isolated IN GND to the second conductor of
the same twisted pair.
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.
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 previous listed events.
GPO
User programmable binary output.
