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 the1V cycle time, then
every 1V cycle can receive a Command.

Commands
• 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 can support a
daisy chain of up to seven attached devices.
However, the FCB camera does not support camera
connections in a daisy chain. Therefore, whenever a
camera is connected for the first time, be sure to use
the address set to confirm the address.
• ID Write
Sets the camera ID.
• Mute
Blanks the screen and sends out a synchronizing
signal.
• Lens Initialization
Initializes the zoom and focus of the lens. Even when
power is already on, it initializes the zoom and the
focus.
