Camera Interface Details
Mode 1: Fixed line scan rate
The Matrox Pulsar sends the RS-422 EXPOSURE1 (EXSYNC) signal to the camera; the
camera awaits the rising edge of the signal and after a short (constant) delay initiates line readout. The line rate is fixed and is determined by the frequency of the EXSYNC signal.
The HSYNC parameter in the DCF specifies the line rate of the camera and therefore the
exposure time. The total line time is currently set to 1045 pixels. The clock rate is 15 Mhz; the line rate is therefore 3.5KHz. The line rate of the camera, and therefore the exposure time, can be modified in the DCF using Matrox Intellicam. Consult the Matrox Intellicam User Guide for more information.
The virtual frame rate for the current settings of the DCF is 287µs x 512 = 146.9µs =
6.8Hz. In each virtual frame there are 512 active lines. The host buffer of the Matrox Pulsar can grab images of up to 2048 x 2048 (4MB) and the display buffer can grab images of up to 2048 x 1024 (2MB)
The time between the rising edge of the EXPOSURE1 and EXPOSURE2 signals is the
exposure time. In order to select the exposure time, the width and deployment time of each EXPOSURE 1 and EXPOSURE 2 must be set in Matrox Intellicam.

Mode 2: Variable line scan rate
PSG FPGA version 3.01 or newer is required.
Line rate is variable and is controlled by the external trigger signal.
Virtual frame size for this DCF is 1024 x 1 x 512
Once it has received the external signal to trigger, the Matrox Pulsar sends the RS-422
EXPOSURE1 (PRIN) signal to the camera to initiate exposure. The Matrox Pulsar will send the RS-422 EXPOSURE2 (EXSYNC) signal to the camera following a delay that is equal to the desired exposure time. A short (variable) delay after receiving the EXPOSURE2 pulse, the camera sends the RS-422 LVAL signal to the Matrox Pulsar to indicate line readout (line valid).

Cabling Requirements
The maximum possible delay between the EXPOSURE2 pulse and the LVAL pulse is calculated to be:
EXSYNC to LVAL = 4µs + 11 MCLK pulses + 4 MCLK pulses + 400ns Maximum = 4µs + (11 x 66.7ns) + (4 x 66.7ns) + 400ns = 4µs + 0.734µs + 0.267µs + 400ns = 5.4µµs
