[. . . ] Application Note: DALSA CL-CB-512A Camera Descriptions Interfacing non-standard cameras to Matrox Pulsar February 6, 1998 512 x 1 x 8-bit Digital video output (RS-422) · Max. data rate is 20MHz · External synchronization required · Exposure control · · · Interface Modes Camera Interface Briefs Fixed line scan rate and variable line scan rate (Binning or no Binning) Video PRIN Mode 1: Fixed line scan rate DALSA CL-CB-512A · EXSYNC STROBE LVAL Matrox Pulsar (with PULSAR/DIG/MOD) 512 x 1 x 8-bit. · DCF configured for 512 lines per virtual frame (256 lines with Binning). [. . . ] · The Timer1 period in the DCF specifies the line rate of the camera and therefore the exposure time. The pixel clock rate is 20 MHz; the line rate is therefore 34. 482 kHz. The line rate and exposure time of the camera can be modified in the DCF using Matrox Intellicam. · The virtual frame rate for the current settings of the DCF is 29µs x 512 = 14848µs = 67Hz. 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 1and EXPOSURE 2 must be set in Matrox Intellicam. · T1=28. 8µs EXPOSURE 1 (PRIN) T2=25µs EXPOSURE2 (EXSYNC) 200ns Video Valid 25. 6µs 26. 30µs · HSYNC (LVAL) For CLCBDE2. DCF (Binning), all details are the same as for CLCBDE1. DCF (no Binning) except that T1 = 31. 8µs and T2 = 25µs and the virtual frame rate for the current settings of the DCF is 32. 2µs x 256 = 8243µs = 121Hz. In each virtual frame there are 256 active lines. Mode 2: Variable line scan rate Line rate is variable and is controlled by the external trigger signal. · 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 initiate line readout. · 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. · PUL-CID-044 2 Application Note: DALSA CL-CB-512A · Interfacing non-standard cameras to Matrox Pulsar February 6, 1998 Camera Interface Details (continued) In no Binning mode, the maximum possible delay between the EXPOSURE2 (EXSYNC) pulse and the HSYNC (LVAL) pulse is calculated to be = 26 strobe pulses = 1. 3µs. · For CLCBDE4. DCF (Binning), all details are the same as for CLCBDE3. DCF (no Binning) except that in each virtual frame there are 256 active lines. TTL external trigger EXPOSURE 1 (PRIN) exposure time 25. 0µs HSYNC (LVAL) variable delay 200ns EXPOSURE2 (EXSYNC) 25. 6µs Cabling Requirements Mode 1: Fixed line scan rate · · PULSAR/DIG/MOD required for digital data, syncs and control signals in RS-422 format. The connections between the OS1 20-pin dual row connector of the camera and the 68-pin connector of the PULSAR/DIG/MOD are as follows: DALSA CL-CB-512A (20-pin dual row connector - OS1) Pin name Pin no.
