Camera interfaces

In 1 – opto-isolated

In 1 is optically isolated and can be used in electrically noisy environments to

prevent false trigger events. Tie Camera GND to Isolated IO GND to complete

the trigger circuit. Compare to the non-isolated trigger, In 1 has a longer prop-

agation time. It can be driven from 5 to 24 V with a minimum current source

of 10 mA. See Camera I/O opto-isolated user circuit example for more informa-

tion.

In 2 – non-isolated

In 2 is non-isolated and can be used when a faster trigger is required and when

environmental noise is inconsequential. The required signal is low voltage TTL

3.3 V. Tie Signal GND to Camera GND to complete the trigger circuit. See Cam-

era I/O non-isolated user circuit example for more wiring information.

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:

Out 1 – opto-isolated

Out 1 is optically isolated and should be used in noisy environments. Out 1

requires a pull up resistor of greater than 1 KΩ to the user’s 5 V logic supply. Tie

Camera GND to Isolated IO GND to complete the external circuit. See Camera I/

O opto-isolated user circuit example for more information.

Caution



Do not exceed 5.5 V on signal inputs unless otherwise

indicated.

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 trig-

ger 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
