21.14 Delivery confirmation
VISCA over IP uses UDP as a communications protocol of the transport layer. Delivery of messages
is not guaranteed for the UDP communication. Delivery confirmation and retransmission should be
performed on the application.
When the controller sends a message to the peripheral device, wait until a reply for the message is
received before sending the next message. You can confirm delivery of messages by managing the
time-out waiting for a reply message sent.
If time out occurs on the controller, loss of one of the following message is considered:
• Command
• Acknowledge message
• Completion message for command
• Inquiry
• Reply message for the inquiry
• Error message
• Inquiry of the VISCA device setting command
• Reply message of the VISCA device setting command.
