9.2.2.2 Timing Chart

As VISCA Command processing can only be carried out one time in a Vertical cycle, it takes the

maximum 1V cycle time for an ACK/Completion to be returned. If the Command

ACK/Completion communication time can be cut shorter than the 1V cycle time, then every 1V

cycle can receive a Command.
