Continuous and asynchronous reset modes
the exposure time is selected using the SHUTTER switch on the rear panel of the camera.
The positions on the SHUTTER switch correspond to the following exposure times:
SHUTTER switch exposure SHUTTER switch exposure
position time (s) position time (s)
0 1/60 9 1/4000 1 1/100 A 1/6000 2 1/125 B 1/8000 3 1/250 C 1/10000 4 1/500 D 1/30000 5 1/1000 E 1/50000 6 1/1500 F for use with 7 1/2000 2 pulse trigger 8 1/3000 camera mode
to select an exposure time of (1/30)s, set the SHUTTER switch on the rear of the camera
to 0 and set switch S201/6 located inside the camera to ON
the camera manual states that in the 1/60N mode, the camera provides the ODD fields of
the output signal on VIDEO1 of the 12-pin connector and the EVEN fields on VIDEO2; however, this was not the case with the camera we tested. Instead, both VIDEO1 and VIDEO2 were alternating between ODD and EVEN fields, i.e., if the output on VIDEO1 was ODD-EVEN-ODD then the output on VIDEO2 was EVEN-ODD-EVEN (the Pulsar can grab from only one of these two outputs at a time). Although we have received confirmation that the camera currently does operate in this way, we are told that its functionality will be altered to match the one described in the manual. This revised functionality will cause the DCFs for the 1/60N camera mode to require modification. Please contact Matrox Imaging Applications at (514) 969-6061 in order to obtain assistance in making these modifications
another modification that we are told will be made to the camera concerns the polarity of
the first field to be output by the camera when in 1/30I mode. Currently the first field that is output is said to be ODD. After modification, the first field to be output will be EVEN. Once this alteration is made there will be a problem with the setting of the field polarity in the DCFs that will manifest itself in one or two ways: the jagged appearance of diagonal lines and/or the absence of either all the odd lines or all the even lines in the acquired image. These problems can be solved by modifying the DCFs at the hardware register level. A hardware register editor is provided by running Intellicam with the
-hwreg option (specifically by running INTELCAM -hwreg). An additional menu item, “HW REGISTER EDITOR”, appears on the main menu screen; select this option using the cursor and the enter key. If diagonal lines appear jagged in the acquired image, the FLDPOL bit of the 16-bit PSG_POLCTL register must be changed. Use the arrow keys to find the PSG_POLCTL register and once there, use the F2 key to view the individual bits of this register.

Again use the arrow keys to find the FLDPOL bit of the PSG_POLCTL register and once
this bit is found, use the F2 key to view the options; use the arrow keys and the enter key to make a selection. When operating the camera in continuous mode, only the FLDPOL bit need be changed to correct for a field inversion. If every second line of the image is missing, causing the image to appear darker, either the odd lines or the even lines are missing from the frame. If this is the case, the FLDSEL bit of the 16-bit PSG_EXTCTL register must be changed. Use the arrow keys to find the PSG_EXTCTL register and once there, use the F2 key to view the individual bits of this register. Use the arrow keys to find the FLDSEL bit of the PSG_EXTCTL register and once this bit is found, use the F2 key to view the options; use the arrow keys and the enter key to make a selection. In asychronous reset mode, both the FLDPOL bit and the FLDSEL bit will have to be changed to correct for a field inversion. If assistance is required in making any necessary modifications to the DCFs, please contact Matrox Imaging Applications at (514) 822­6061
for the camera we tested, we found that in asynchronous reset mode the connection from
the TTL_EXPOSURE1 output of the PLS-TTL-CABLE to the TRIGGER IN input of the camera had to be made before power was supplied to the camera or the camera would not reset on the trigger
in addition to the DCFs, PSG FPGA version 3.53 or newer is required; if this version is
not on your release of the MIL driver for Pulsar, the newest version can be found on the BBS or at the FTP site
The DCF(s) mentioned in this application note can be found on the MIL and MIL-Lite CD, or our FTP site (ftp.matrox.com). The information furnished by Matrox Electronics System, Ltd. is believed to be accurate and reliable. Please verify all interface connections with camera documentation or manual. Contact your local sales representative or Matrox Sales office or Matrox Imaging Applications at 514-822-6061 for assistance.
