© Copyright, Alliance Laundry Systems LLC –DO NOT COPY or TRANSMIT
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 Ω1/2 Watt terminating resistor and
2 560 Ω1/4 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 Ω1/4 Watt resistor
connects between the black and green wires of the
network cable.

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 Ω1/2 Watt terminating resistor
connects between the red and black wires of the
twisted pair network wiring.
C. Connecting the Machines to the
PC and Each Other
(For up to 124 machines or 4,000 feet of
network length)
1. Run the black/red twisted pair wire to the first
machine to be connected. Follow whatever
sequence is most convenient for store layout.
Be sure you have DISCONNECTED the PC or
laptop before you begin wiring.
2. Locate the network board header on the back of
the machine. refer to Figure 4
NOTE: Stacked units will have two connectors.

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. Remove the connector (part number 210099)
from the literature packet or kit.
5. Insert the wire into the connector. The red
incoming wire goes into slot 1 and the black
incoming wire goes into slot 2. Check that only
wire, not insulation is inside the connector.
Incorrect installation could result in the
network not communicating. Secure the wires
in place by tightening the screws on top of the
connector. refer to Figure 6
6. Cut an ample length of wire to reach the next
machine’s connector. The wire should be long
enough to move the machine for maintenance,
but not so long as to interfere with normal
operation. refer to Figure 7
7. Strip 1/4 if the insulation and place the red
outgoing wire into slot 4 and black outgoing
into slot 5. Follow the same procedure in step 5.
8. Connect the wired connector to the Network
Board Header. Refer to Figure 7.
9. Run the wire to the next machine and follow
steps 3-8 until all machines have been
connected. Refer to Figure 7.
10. On the final machine, wires should be run into
slots 1 and 2 as on all previous machines. A 120
Ohm, 1/2 Watt terminating resistor should be
placed in slots 4 and 5 to terminate the
connection at the end of the network. Refer to
Figure 7.
NOTE: It is recommended that some type of
terminal strip be used when connecting banks of
machines onto a network. This should be done so
that a bank of machines can easily be bypassed in
the network for purposes such as debugging
network problems. A barrier block (such as part
number 210161) may be used for this purpose.

D. Connecting the Repeater
to the PC
Refer to Figure 8
1. Attach one of the 210150 Network Cables to
segment 1 of the repeater.
2. Connect the RED and BLACK wires of that
Network Cable to the terminal strip coming
from the computer (RED to RED and BLACK
to BLACK). Do not connect the GREEN wire.
3. When repeater is used with a desktop PC, the
bias resistor in the repeaater must be removed.
Open the repeater and remove jumpers J3 and
J4. Refer to the manual included with the
repeater for specific instructions.
NOTE: Ensure that only the bias resistors that
correspond to segment one (PC connection) are
removed.
4. Connect one of the 210150 Network Cables to
segment 2 of the repeater.
5. Connect the RED and BLACK wires of that
Network Cable to the terminal strip going out to
one leg of the network (RED to RED and
BLACK to BLACK). Do not connect the
GREEN wire.
6. Terminate the last machine on this leg with a
120 Ohm 1/2 Watt resistor.
NOTE: Up to 124 nodes may be connected to any
given segment coming off the repeater. A total of
250 nodes may be connected to the network.
7. Repeat steps 4 –6 for the remaining 2 segments
as required. There is no need to connect a cable
or a terminating resistor to an unused segment
on the repeater.
8. Connect the bayonet style connector of the wall
adapter to the 12 VDC input on the repeater.
9. Connect the wall adapter to a 120 VAC 60 Hz.

E. Connecting the Repeater
to a Laptop
NOTE: If connecting the repeater to a laptop, a
terminating resistor must be used. Refer to the
section on “Interfacing a Laptop to Machines” on
page 5. Refer to Figure 9.
F. Tests
Once the network has been wired, run the
following tests to ensure proper installation.
1. Power off all machines before test.
2. Check for continuity of 2 wires running from
the central PC.
a. Disconnect the wires from the PC
b. Check for 120 Ω± 20%. A much higher
reading indicates an open circuit. This is
caused by a break in the network. A much
lower reading indicates a short in the
network, which means the network is only
communicating to a certain point in the
network.

Troubleshooting

Network Interface Boards
Wire Break - Any time there is a wire break on the
network, all machines on the opposite side of the break
from the Central PC will become unable to
communicate with the Central PC. Also,
communication may become less reliable for those
nodes which are still on the network, since the
terminating resistor on the end of the network has been
separated from the network.
Short on the Line or on the Network Board - If
there is ever a short on the network, the entire network
may be unable to function. However, if the short is on
the far end of the network, those nodes closest to the
Central PC may be able to communicate with the
Central PC to some degree.
Shorts may be isolated by removing the RS-485 cable
from the PC, and putting an Ohm-meter on the cable.
Next, remove a series of machines at the end of the
network, and check the meter. If there is no longer a
short, the short is somewhere in the chain of machines
removed from the network. If there is still a short, move
the break in the network close to the Central PC until a
location is found where the short can be eliminated. By
repeating this process of elimination, a short in either
the cable or on a network board may be isolated.
Wires Flipped on the Network - Correct polarity
must be observed when installing machines on the
network. If a machine is installed with the wrong
polarity at either the input or output (but not both) at the
connecting terminals, all machines further down the
series will be unable to communicate with the Central
PC. If, however, both the input and output are wired
incorrectly, only that machine will be unable to
communicate. If the wires at the card on the PC are
flipped, none of the machines will be able to
communicate with the Central PC.
NOTE: Both shorts or flipped wires will cause
numerous errors on the central PC, including
“Protocol Errors”and numerous “Unable to
Connect”messages.
Nodes on the Same Address - If two or more nodes
share the same address, there will be intermediate
levels on the network, which may be observed with an
oscilloscope. These intermediate levels will occur
whenever the Central PC commands a response from
the address at which there are multiple nodes. In most
cases, the Central PC will not be able to communicate
successfully with any of the devices at this address. In
some cases, however, if two nodes share the same
address with one close to the Central PC and the other
on the opposite end of the network, the node closest to
the PC may be able to overpower the other, and
complete a valid communication. The one at the far
end, in this case, will not be able to communicate at all
with the Central PC.
NOTE: Nodes on the same address will cause
numerous errors on the central PC, including
“Protocol Errors”and numerous “Unable to
Connect”messages.
Jabbering Node - In this condition, a node on the
network is transmitting erratically. If the node is
transmitting constantly, this condition may bring down
the entire network. In other cases, it may transmit
periodically. If this is the case, some communications
will be able to get through, until the node begins
jabbering again. A jabbering node may be detected by
disconnecting the network from the PC and monitoring
the network with an oscilloscope. Since the PC initiates
all communications, the scope should show no
communications once the PC is removed. If the scope
indicates that there is communication occurring,
