SC modified webcam settings
For proper work of SC modified webcam it is
necessary to properly set parameters, which determine
control of webcam. It can be done in Settings dialog - in
SC Long Exposure modified camera - Check it if you want to use Long exposures with SC modified webcam
Control Port - Specifies the port used for controlling camera. Current version of K3CCDTools supports either parallel or serial ports. If your parallel port has another address, you can specify its address in K3CCDTools.ini file, e.g.:
The next items represent control bytes which are sent to parallel/serial port. They are expressed in binary code for easier settings. This means, that the bit 0 is in the most right side and bit 7 is in the most left side. 1 represents HI level, 0 represents LOW level. You can change individual bits by clicking them by left mouse button.
Initialization - Specifies initialization byte, which is sent to port in K3CCDTools start-up. For webcam modified according to Steve Chambers it is necessary to set to lowest 4 bits to 1. Without sending Initialization byte the camera may not work properly (black frames) also in not long exposure mode. It is especially necessary for webcams without hardware switch for controlling long exposure mode.
LXMode ON - Specifies initialization byte, which is sent, when Long exposure dialog box is recalled. By default the bit 3 is set to LOW level (shutter disable).
LXAmp ON Mask - Specifies the mask, which is used for switching CCD amplifier ON/OFF. It is used with XOR operator:
Exposure Field A - Specifies the byte, which is sent, when Field A is exposed (the 1st sub-frame). The port byte value must be specified with AMP OFF. (Amp ON is achieved by applying LX Amp ON mask).
Exposure Field B - Specifies the byte, which is sent, when Field B is exposed (the 2nd sub-frame). The port byte value must be specified with AMP OFF. (Amp ON is achieved by applying LX Amp ON mask).
Exposure Field AB - Specifies the byte, which is sent, when whole frame is exposed (both fields A+B). The port byte value must be specified with AMP OFF. (Amp ON is achieved by applying LX Amp ON mask).
Exposure End - Specifies the byte, which is sent, when exposure is stopped. It must include AMP ON.
LXMode OFF - Specifies the byte, which is sent, when Long exposure dialog box is closed.
Post Exposure Time - Specifies the time interval between end of exposure and frame reading.
Turn AMP ON lead - Specifies the time which is needed for switching AMP ON before end of exposure.
Default Amp Mode - Specifies the default CCD amplifier mode - ON or OFF. Default mode is set when Long Exposure dialog is recalled.
Log LX exposure to file - Enables to log the exposure data for each captured frame to file. The data contains frame number, time of start of exposure and length of exposure (in ms precision).
