VISCA™ Communication Specifications
VISCA™ packet structure
The basic unit of VISCA™ communication is called packet (Fig. 3). The first byte of the packet is called header and
comprises the sender’s and receiver’s addresses. For example, the header of the packet sent to the FCB camera of address 1
from the controller of address 0 is hexadecimal 81H. The packet sent to the FCB camera of address 2 is 82H. In the command
list, as the header is 8X, input the address of the FCB camera at X. The header of the reply packet from the FCB camera of
address 1 is 90H. The packet from the FCB camera of address 2 is A0H.
Some of the commands for setting the FCB camera can be sent to all devices at one time (broadcast). In the case of broadcast,
the header should be hexadecimal and 88H.
When the terminator is FFH, it signifies the end of the packet.
