This Manual outlines an RS-232C control protocol and
command list for certain Sony cameras from which
control software can be developed.

Overview of VISCA
In VISCA the device outputting commands, for
example, a computer, is called the controller. The
device receiving the commands, an FCB series camera
is called the peripheral device. In this case, an FCB
series camera, is itself one of the peripheral devices.
In VISCA, up to seven peripheral devices like the FCB
series camera can be connected to one controller using
communication conforming to the RS-232C standard.
The parameters of RS-232C are as follows:
• Communication speed: 9.6 kbps/19.2 kbps/
38.4 kbps
• Data bits : 8
• Start bit : 1
• Stop bit : 1/2
• Non parity
Peripheral devices are connected in a daisy chain. As
shown in the following figure, the actual internal
connection is a one-direction ring, so that messages
return to the controller via the peripheral devices. The
devices on the network are assigned addresses.
The address of the controller is fixed at 0. The
addresses of the peripheral devices are 1, 2, 3 ... in
order, starting from the one nearest the conttoller. The
address of the peripheral device is set by sending
address commands during the initialization of the
network.
