Camera Out 1 and Camera Out 2
These signals only function as outputs and can be configured as follows:
Exposing Corresponds to when camera is integrating light.
Trigger Ready Indicates when the camera will 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.
Any of the above signals can be set for active high or active low.
Camera Out 1 is isolated and should be used in noisy environments. Camera Out 2 is non-
isolated and can be used when environmental noise is not a problem and when faster
response is required.
Camera Out 1 will require a pull up resistor of greater than 1Kohm to the user’s 5V logic
supply.
See Trigger Schematics in Addendum for wiring information.
RS-232 RXD and RS-232 TXD
These signals are RS-232 compatible. These signals allow communication from the host
system via the Ethernet port to a peripheral device connected to the camera. Note that
these signals are not isolated and therefore careful attention should be used when
designing cabling in noisy environments.
Isolated Ground
Isolated Ground must be connected to the user’s external circuit ground if Sync Input 1
or Sync Output 1 is to be used.
Signal Ground
Signal Ground must be connected to the user’s external circuit ground if Camera Input 2
or Camera Output 2 is to be used or if the RS-232 port is to be used. Note that Signal
Ground is common with Power Ground however it is good practice to provide a separate
ground connection for power and signaling when designing the cabling.
Video Iris
This signal can be used to drive the video input of a video iris lens. See Addendum.
