VISCA

is a protocol developed by Sony for

controlling a consumer's camcorder.

Overview of VISCA

In VISCA, the side outputting commands, such as

a computer, is called the controller, while the side

receiving the commands, such as a BRC-X400/

X401, SRG-X400/X402/201M2/X120/HD1M2

called the peripheral device. In VISCA, up to

seven peripheral devices including this unit can

be connected to a single controller using

communication conforming to the RS-422

standard. The parameters of RS-422 are as

follows.

• Communication speed: 9600 bps/38400 bps

• Data bits : 8

• Start bit : 1

• Stop bit : 1

• Non parity

Flow control using XON/XOFF and RTS/CTS, etc.,

is not supported.

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 peripheral devices are assigned to the

addresses, 1, 2, 3... in the connected order,

starting from the one connected nearest to the

controller. These addresses are set when the

controller sends address commands during

initialization of the network.

Note

Each VISCA equipment has VISCA IN and VISCA

OUT connectors.

Set the DTR input (the S output of the controller)

of VISCA IN to H when controlling VISCA

equipment from the controller.
