Mode 2: Asynchronous reset (E-DONPISHA-II)
• The frame rate is determined by the period of the TTL external trigger.
• The external trigger is input on the Matrox Pulsar via the analog trigger input.
• Once this external trigger is received, the Matrox Pulsar generates an EXPOSURE1
(TRIGGER) pulse, which in turn initiates camera exposure.
• The exposure time is the EXPOSURE1 (TRIGGER) period plus a fixed internal camera
delay of 8 µsec.

Requirements
Video (Video Out)
Mode 1: Continuous
• IMG-7W2-TO-5BNC (red BNC) or IMG-7W2-TO-1BNC cable required for video output
of camera.
Mode 2: Asynchronous reset (E-DONPISHA)
Video Valid
• IMG-7W2-TO-5BNC and PLS-TTL-CABLE cables required for TTL external trigger signal
and for video output of camera.
• TTL external trigger source should be connected to the TTL trigger input of the IMG-7W2-
TO-5BNC cable.
• Connections between the 37-pin connector of the Matrox Pulsar (PLS-TTL-CABLE) and
the 12-pin connector of the camera are as follows:
