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. 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.
