Overview of Functions

VISCA commands form the basis of camera control.
Timing Chart
As VISCA Command processing can only be carried
out once in a Vertical cycle, it takes the maximum 1V
cycle time for an ACK/Completion to be returned.
If the Command ACK/Completion communication
time can be cut shorter than the1V cycle time, then
every 1V cycle can receive a Command.

Powers the camera on and off. When the power is off,
the camera is able to accept only the lowest level of
VISCA Commands; the display and other features are
turned off.
Clears the Command buffer of the FCB series
camera. Clearing the buffer can also be carried out
from the control application software when the power
is on.
VISCA is a protocol, which normally can support a
daisy chain of up to seven attached devices.
Whenever a camera is connected for the first time, be
sure to use the address set to confirm the address.
Sets the camera ID.
Blanks the screen and sends out a synchronizing
signal.
Initializes the zoom and focus of the lens. Even when
power is already on, it initializes the zoom and the
focus.
A pixel blemish-masking feature is used to reevaluate
overall CCD pixel blemishes and mask severely
flawed pixels automatically upon receiving the
COMP SCAN command. This feature helps to mask
the flaws found in CCD imagers, even after the
camera has been powered on for some time.
