Connections & Installation (continued)
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.
Multi-Drop Communication System (continued)
CAUTIONS
●
The AC 24 V power supply must be isolated from the primary line. (ISOLATED POWER ONLY)
●
In order to prevent an excessive current flow through the power supply wire or camera due to a short circuit, a fuse must be
installed in the power supply line.
