Overview of Functions
VISCA commands are the basis of camera control.
Timing Chart
As VISCA Command processing can only be carried
out one time 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 the 1V cycle time, then
every 1V cycle can receive a Command.

In general
• Power On/Off
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.
• I/F Clear
Clears the Command buffer of the FCB camera.
Clearing the buffer can also be carried out from the
control application software when the power is on.
• Address Set
VISCA is a protocol, which normally supports a daisy
chain of up to seven connected cameras via RS-232C
interface. In such cases, the address set command can
be used to assign addresses from 1 to 7 to each of the
seven cameras, allowing you to control the seven
cameras with the same personal computer.
Although the FCB camera does not support direct
connection of cameras in a daisy chain, be sure to use
the address set command to set the address whenever
a camera is connected for the first time.
• ID Write
Sets the camera ID.
• Mute
Blanks the screen and sends out a synchronizing
signal.
• Lens Initialize
Initializes the zoom and focus of the lens. Even when
power is already on, it initializes the zoom and the
focus.
