§ Matrox Pulsar receiving HSYNC (LINE ENBLE), VSYNC (FEN), PIXEL CLOCK

(CCLK @ 20 MHz), and video signals.

§ DCF used: MD4013.DCF

Mode: Control

§ Once it has received the external signal to trigger, the Matrox Pulsar sends an

EXPOSURE2 (SHUT) signal to the camera. The camera awaits the rising edge of the
signal, at which point it initiates exposure. Matrox Pulsar sets the exposure time; the
camera will expose for as long as the EXPOSURE2 (SHUT) signal is high. The camera
initiates frame readout upon arrival of the falling edge of the EXPOSURE1 (FST) signal.

§ The image captured by Matrox Pulsar resides scrambled in the host buffer and must be

reconstructed. The original image is stretched and folded over; in the host buffer, the pixel
columns from the second half of the original image are interleaved in a “folded paper”
fashion with the pixel columns from the first half of the original image.

§ The 30 ms immediately following the falling edge of the Frame Start signal cover the shift

and readout of the entire array; therefore, in order to avoid smearing, the camera must not
be triggered for a minimum of 30 ms after a Frame Start signal is received.

• DBHD68-TO-OPEN (open end) cable and PULSAR/DIG/MOD board required for digital

data, synchronization and control signals.

• TTL external trigger source should be connected to the TTL Trigger Input of the DBHD68-

TO-OPEN (open end) cable.

• Connections between the 68-pin connector of the camera and the 68-pin connector of the

PULSAR/DIG/MOD are as follows:
