Command ListSocket numberThis unit has two sets of sockets (buffers) forcommands, so that up to two commands including thecommands currently being executed can be received.When this unit receives commands, it notifies thesender which socket was used, using the socket numberof the Acknowledge message. As each of thecompletion message and error message also has asocket number, you can identify which command hasended.When sending the commands continuously, be sure towait until an Acknowledge message or error message ofthe first command is returned, then send the nextcommand. (Otherwise, it is impossible to identify towhich command the socket number belongs.)Even when two sockets are being used, the devicesetting commands and some inquiry messages can beexecuted. The Acknowledge message is not returnedfor these commands and inquiries, and only thecompletion message of socket number 0 is returned.Command execution cancelTo cancel a command which has already been sent,send a Cancel command as the next command.Cancel Packet NoteCancel 8X 2Y FF Y = socket numberX = 1 to 7: Address of this unit in the daisy chain, Y = socket number** Locked to “X = 1” for VISCA over IP.Error message “Command canceled” will be returnedfor this command, but this is not a fault.
