This 0.7-meter prefabricated cable provides the necessary electrical impedance matching for the system's extension bus. Specifically, any configuration utilizing the TK850V007 connection requires the TK851 to act as the terminal reference point. This ensures signal reflection suppression and maintains high-speed data integrity between the primary controller and its expanded communication modules.
