Wiring to the DeviceNet controller (LK-DN100)
The LK-DN100 field network connector (terminal block) is to be wired as explained below.
Connect the cable by matching the color of the wires to the colors on the sticker affixed to the
DeviceNet connector.
Typical connection
Refer to the manual for the DeviceNet master unit for wiring details.
Connecting terminators
A terminator must be connected to both ends of the
trunk line. The terminators must be connected to
reduce signal reflection and stabilize communication.
Terminator resistance: metal-film resistor 121 ohms,
1%, 1/4W
The terminators must be connected, otherwise, DeviceNet will
not communicate properly.
