• RS-485 interface:E5AK-TM03M
• Up to 32 controllers including a host computer can be connected .
• The total cable length should not exceed 500 meters. Use shielded twisted pair leads (AWG28 min.) for the cables.
• Attach terminators to the controllers at both ends of a series of controllers connected in an open configuration. For example, in the configuration on the left, connect terminators to the
host computer and the unit No.30, and do not connect terminators to connector Nos. 0 to 29.

(1) Attach the watertight packing from the terminal side and then insert
the controller to the panel.
(2) Fit the mounting bracket (supplied) into the grooves on the top and
bottom sides of the rear case.
(3) Alternately tighten the top and bottom screws on the mounting bracket
applying equal pressure a little at a time until the rachet rotates freely.
