Alliance Laundry Systems NK100, NK101, NK120 C. Connecting the Machines to the PC and Each Other

Installation

5.Run the wires of the network cable into the different circuits of the terminal strip and hold them in place while tightening the screws on top of the strip. Refer to Figure 3.

6.Carefully strip 1/4" of the insulation from the black and red twisted pair wire. If too little insulation is stipped, and insulation is inside the connector, the network will not communicate. If too much is stripped, the wires will short. Refer to Figure 5.

7.Place the black and red twisted pair wire into the terminal strip and hold the wires in place while tightening the screw on top of the terminal strip (connect black wire to black wire and red wire to red wire). Refer to Figure 3.

NOTE: The 120 Ω 1/2 Watt terminating resistor connects between the red and black wires of the twisted pair network wiring.
