A system that does not employ the RM-P2580 as the controller.
MEMO
●Be sure to terminate the control signal cable at both ends. The cables (length of stub) connecting pieces of non-terminated equipment (cameras
or controllers) must be as short as possible. If the length of stub is too long, control precision may suffer.
