Installation

A. Interface PC and Machines

1.The Data Connector should be attached to the network board on the back of the PC. The PC must be Pentium 166 or better, have 32 mb RAM minimum, a CD drive, a mouse and Windows 98 or higher.

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

3.The black/red twisted pair (Alliance Laundry Systems recommends using American Electronic Wire Co. part number 781816PFO - 2Z) wires should be connected to slots 1 and 2 (red from 1, black from 2). Refer to Figure 6.

1.Attach the RS-485 cable to the Network Card and insert the card into the PCMCIA Slot on the laptop.

2.Attach the network cable to the RS-485 cable.

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

4.Place a 120 Ω 1/2 Watt terminating resistor and 2 560 Ω 1/4 Watt bias resistors into the terminal strip. Refer to Figure 3.

NOTE: One of the 560 Ω 1/4 Watt bias resistors connects between the white and red wires of the network cable. The other 560 Ω 1/4 Watt resistor connects between the black and green wires of the network cable.
