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. The PSG_SETVCNT register controls the exposure time: Exposure time = (16381 lines - PSG_SETVCNT) 63. 49µs + 42. 2µs Or PSG_SETVCNT = 16381 lines - (exposure time - 42. 2µs) / 63. 49µs PUL-CID-020 3 Interfacing non-standard cameras to Matrox Pulsar Sony XC-75 Special Considerations Continued Application Note: May 31, 1996 The value of PSG_SETVCNT must be an integer number of linetimes (one linetime = 63. 49µs) and must be set in hexadecimal. The exposure time can vary from 42. 2µs to 13ms. An exposure time of 42. 2µs results when PSG_SETVCNT is set to 3FFD in hex (16381 lines); setting PSG_SETVCNT to 3F32 in hex (16178 lines) yields an exposure time of 13ms. The default exposure time in this DCF is 10ms; the corresponding value of PSG_SETVCNT is 3F60h (16224 lines). The register is set in the following way: PSG_SETVCNT = 3F60H When computing the hardware registers, the following question may be asked: "Some registers have been manually edited. Answer "no" to this question and to all questions that follow. These instructions must be followed very carefully; the only register that should be modified is the one mentioned above. Please consult Matrox Imaging Applications at (514) 822-6061 if assistance is required. · The time between external trigger signals must be greater than the sum of the exposure time and the frame transfer time (16. 7ms); since the default exposure time is 10ms, the trigger rate must be less than 37. 5Hz for the current settings of the DCF The camera must be modified in order to operate in S-DONPISHA mode. The following settings are required inside the XC-75 head: · MB-403 board: JR1 must be shorted JR3 must be shorted JR2 must be set to the T position SG-199 board: JR7 and JR 8 must be open · The connections described in this document can also be achieved by using the JB-77 junction box.
