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.
B. Interfacing a Laptop to Machines
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.
