VISCAa/RS-232C
The VISCAa is a protocol which controls consumer camcorders developed by Sony. The command which can be used will differ
for each product. Refer to the command list of each product.
Outline of VISCAa
In the VISCAa, the side outputting commands such as the computer is called the controller, while the receiving of the
commands such as the FCB camera is called the peripheral device. The FCB camera serves as a peripheral device of
VISCAa. In VISCAa, up to seven peripheral devices such as the FCB camera can be connected to one controller using
communication conforming to RS-232C. The parameters of RS-232C are as follows.
Y Communication speed: 9600 bps
Y Data bits: 8
Y Start bit: 1
Y Stop bit: 1
Y Non parity
Y MSB first
Flow control using XON/XOFF and RTS/CTS, etc. is not supported.
The peripheral devices are connected in a daisy chain. As shown in Fig. 1, 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 the order from the one nearest
to the controller. The address of the peripheral device is set by sending address commands during the initialization of the
network.

The VISCAa devices each have a VISCAa IN and VISCAa OUT terminal.
Set the DTR input (S output of the controller) of VISCAa IN to H when controlling from the controller.
