VisuaLink 128/384 Engineering Guide Chapter 1 1.5 Communication Procedure There is no procedure for communication between a console and VisuaLink as a rule. Therefore, a communication line is presumed to be error-free. When it is remotely operated with a modem, efficient operation may not be expected when a line error occurs. Because of this, in a remote control, a modem with error correction feature shall be used, or VisuaLink shall be checked for operation. Command/Response Procedure Visua
