Virtual Serial Port Method
1. Open QuickCam. Refer to section 248H3.1
running the application.
QuickCam Interface for details on installing and
2. Select Configure → Virtual Serial Port to enable or disable the virtual serial port.
Some camera control tools can connect only to a Windows system serial port. To avoid
asking for changes from camera manufacturers, two serial COM ports in the PC can be
linked together to share the serial channel to the IP engine. Through their linkage, data
written to one port can be read by the other port, and vice-versa.
These linked serial COM ports can be either "virtual" or physical. To set up virtual ports,
use a virtual serial port driver. Some good virtual serial port drivers are available at:
http://www.softinfinity.com/ or http://www.virtual-serial-port.com/.
Alternatively, if a PC has two free physical serial ports, they can be connected together
and used as a pair, in the same manner as a virtual serial port driver.
The Serial Port Configuration dialog box allows you to attach the serial channel in
QuickCam to one port in a serial port pair, whether a physical pair or virtual pair.
Therefore, an external application needs simply to connect to the other serial port of the
pair to communicate with the camera.
3.3 First Power Up Camera Settings
When the camera is powered up for the first time, it operates using the following factory
settings:
• High sensitivity mode
• Forward CCD shift direction
• No binning
• Exposure mode 7 (Programmable line rate & max exposure time).
• 5000 Hz line rate
• Factory calibrated analog gain and offset
• Factory calibrated FPN and PRNU coefficients using the following process: line rate
of 5000 Hz, analog gain calibrated to an average pixel value of 248 DN, fpn
calibration, prnu calibration, 12 bit output, 9600 baud rate, exposure mode 2.
Notes: The FPN and PRNU coefficients are factory calibrated at a 5 kHz line rate and 0dB
gain setting. While the factory setting baud rate is 9600, QuickCam sets the baud rate to
57600 at startup.
