Overview of Functions
VISCA commands are the basis of camera control.
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-H11 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. In this
case, if addresses from 1 to 7 are assigned to each of
7 devices, you can control seven cameras with the
same personal computer. However, the FCB-H11
camera does not support connection of cameras 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.
Zoom
The camera employs an 10× optical zoom lens
combined with a digital zoom function allowing you to
zoom up to 120×.
Lens specifications: Optical 10×, f = 5.1 to 51 mm
(F1.8 to F2.1)
The horizontal angle of view is approximately 50
degrees (wide end) to 5.4 degrees (tele end).
Digital Zoom enlarges the center of the subject by
expanding each image in both the vertical and
horizontal directions. When 12× digital zoom is used,
the number of effective picture elements in each
direction reduces to
1
/12 and the overall resolution
deteriorates.
You can activate the zoom in the following two ways:
•By pressing the TELE or WIDE buttons on the
camera.
•Using a VISCA Command
Using Standard Mode
Using Variable Mode
There are eight levels of zoom speed.
Direct Mode
Setting the zoom position enables quick
movement to the designated position.
