o False operation panel command type
This system is used to specify operations of this unit from a PC as if operating the actual operation button of the remote
control while viewing the output video. Each command corresponds to the operation button of the remote control.
• Input confirmation type
Send commands as if operate the buttons of the remote control. As a general rule, do not send commands continuously,
but send the next command after checking that the present command has been executed and completed. After sending
a command, the command execution result, error type, and command name can be checked by the status returned from
the unit. To check the actual execution, view the output screen of the unit on the monitor screen.
Example) Playing back the recorded data using still-frames.
