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.
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.

2. Check for continuity of 2 wires running from
the central PC.
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.
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.
F. Tests
Once the network has been wired, run the
following tests to ensure proper installation.

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.
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.
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.
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,
individually remove each node from the network and
use the scope to check for communication from that
node.
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: Jabbering nodes will cause numerous
errors on the central PC, including “Protocol
Errors” and numerous “Unable to Connect”
messages.
NOTE: Both shorts or flipped wires will cause
numerous errors on the central PC, including
“Protocol Errors” and numerous “Unable to
Connect” messages.

Troubleshooting
If a Network Board is present, it is helpful to eliminate
it, if possible, from the circuit temporarily for
troubleshooting purposes. Unplug the harness from the
NWB to the Card Reader, and also unplug the harness
from the NWB to the FEC. Next, connect the harness
which is used to connect a Card Reader directly to the
FEC.
Card Insertions not recognized by
the card reader
All card insertions should be reflected on the FEC
display in some manner. For example, if a valid cash
card is inserted into the reader, the FEC display should
show the balance on the card.
NOTE: This harness is not included in machines
containing a NWB. The individual performing the
service to the machine will have to have this
harness.
A simple test is to insert any non-smart card (credit
card, etc.) into the reader. The display should display
an EC:20. This indicates that the reader recognizes a
card has been inserted, but it cannot read it. Also this
verifies that the reader is communicating successfully
with the Front-End Control (FEC).
If the EC:19 disappears once the NWB has been
removed (allow approximately 120 seconds), the NWB
may need to be replaced, since the reader was able to
communicate with a direct link to the FEC. Ensure that
the reader is now operating properly by inserting
several cards in the reader, and looking for the
appropriate response on the FEC display.
If the card insertions are not reflected on the FEC
display, one of the following conditions has occurred:
• Card reader harness not hooked up or wired
incorrectly.
• Card reader is not recognizing card insertions.
Once the NWB is removed from the circuit, continue to
"NWB Not Present" below.
• Card reader is not capable of communicating with the
FEC.
Network Board Not Present - Begin by checking the
voltage to the card reader. The following
• If a network board is present, it has malfunctioned.
• FEC has malfunctioned, and is not supplying power
to the reader.
measurements should be taken at the 14-pin header on
the card reader. There should be between 24 and 38
volts DC across pins 3 and 12. This voltage must be
present, or the reader will not operate. Also, there
should be 5 volts DC across pins 10 and 12. This
voltage must be present, or the FEC will not recognize
that the card reader is present.
• FEC has malfunctioned, and is not capable of
communicating with the reader.
If the FEC senses that a card reader is present and the
reader fails to communicate with the FEC, it will
display an EC:19 error after 2-1/2 minutes. However, if
the FEC never recognized that the reader was present at
power-up, there will be no error displayed to indicate
that there is no communication with the reader.
If the voltages mentioned above are found to be present
at the reader’s 14-pin header and the reader is not
functioning correctly, the harness may be bad, the FEC
may be bad, or the card reader may be bad.
EC:19
First, disconnect the reader from the 14-pin header, and
re-connect it. Wait about 20 seconds. If there was an
EC:19 on the display, check the FEC display to see if
the EC:19 has gone away. If it has, the communication
has been re-established. The card reader may have
experienced a lock-up condition, and should run fine
once it has been reset by powering down and up again.
Whether or not there was originally an EC:19 on the
display, try several cards in the reader to ensure correct
operation.
NOTE: An EC:19 error indicates that the FEC
recognizes that there is a Card Reader present, but
it has not received a communication from it in the
last 2-1/2 minutes.
Network Board Present - If a Network Board (NWB)
is present, it is possible that it has malfunctioned. A bad
NWB can prevent the reader from communicating with
the FEC, resulting in an EC:19. Before powering down
the unit, examine the LED on the NWB. If the LED is
NOT flashing one second on/one second off, it is not
functioning correctly. It will need to be either reset ( by
powering down then up again) or replaced.

Troubleshooting
If the EC:19 does not clear or the FEC display still does
not reflect a card insertion, try substituting the harness
from the FEC to the reader with a known good harness.
Wait about 20 seconds. Check the FEC display to see
if the EC:19 goes away, and that FEC does reflect the
card insertions. If both conditions are satisfied, the old
harness was bad, and the new one should be used to
replace it. Try several cards in the new reader to ensure
correct operation.
EC:26 – Card Write Error
EC:26 errors can occur in cases where neither the
reader and the card which caused the EC:26 are faulty.
This can occur for the following reasons:
• The reader and card contacts are not making a good
connection due to dirty contacts.
• Intermittent poor connections.
• The user not inserting the card properly.
If the EC:19 does not clear or the FEC display still does
not reflect a card insertion, try substituting another card
reader. Wait about 20 seconds. Check the FEC display
to see if the EC:19 goes away, and that FEC does
reflect the card insertions. If both conditions are
satisfied, the old reader was bad, and the new one
should be used to replace it. Try several cards in the
new reader to ensure correct operation.
Therefore, it is necessary to try numerous cards
numerous times before deciding whether an individual
card or reader is in need of replacing.
If an EC:26 error occurs once on a given card, and does
not happen again in later transactions, the card and
reader are probably OK, and neither would need to be
replaced.
If substituting with a new known good reader and a
new known good harness does not clear the EC:19 and
allow card insertions to be displayed by the FEC, the
Front-End Control will probably need to be replaced.
If a given card repeatedly gives EC:26’s, the card will
need to be replaced.
If a given reader repeatedly gives EC:26’s with a
variety of cards, the reader will need to be replaced.
EC:20 – Error Reading Card
Other Errors
EC:20 errors can occur in cases where neither the
reader and the card which caused the EC:20 are faulty.
This can occur for the following reasons:
The following errors should only occur if a firmware
load has been attempted on the card reader. Under any
other condition, if an EC:2A, EC:2C, EC:2D, EC:2E,
EC:2F or EC:30 appears, the reader should be replaced.
• The reader and card contacts are not making a good
connection due to dirty contacts.
• Intermittent poor connections.
• The user not inserting the card properly.
Therefore, it is necessary to try numerous cards
numerous times before deciding whether an individual
card or reader is in need of replacing.
If EC:20’s are consistently received on an individual
card, but not on others, the card which gives the errors
may need to be replaced
If EC:20’s occur often with different cards, the card
reader’s contacts should be cleaned. If, after cleaning,
the problem persists when numerous cards have been
tried numerous times, the reader is not reading cards
properly and should be replaced.

Test of Communications Between FEC and NWB
Using LED - Power down the NWB by disconnecting
header H1. Re-connect H1. Approximately 15
seconds after H1 is reconnected
(7 LED flashes), the LED should flash rapidly 3 times,
indicating that it is beginning communication with the
FEC. Two LED flashes later, the LED should flash
rapidly 3 times again, indicating the end of a successful
communication sequence. If this does not occur, the
NWB is not communicating with the FEC.

Once it has been determined that the processor on the
NWB is correctly executing the NWB code, the service
personnel may now check for the following other
possible malfunctions of the NWB (and/or the FEC).
When the operation of the Network Board is suspect,
the state of the LED may be examined to determine
whether the Network Board is operating properly.
• NWB is not communicating with the FEC
• NWB is not allowing the Card Reader to
communicate with the FEC
Network Board Operating LED Test
• NWB is not communicating with the PC
LED is Flashing One Second On / One Second Off -
This is what the LED should be doing in normal
operation. If the LED is following this sequence, the
processor on the board is executing the code correctly.
However, there may still be other problems with the
board.
Network Board to Front-End Control
Communication Problems
NWB will not Communicate with FEC - If the NWB
is not communicating with the FEC, the NWB, FEC, or
Harness may be at fault. For the following cases, use
the Network Board Communicating LED test
previously described to test the communication link
between the FEC and the NWB using the LED.
LED is Constantly Off - If the LED is constantly off,
there is probably no power to the NWB. There must be
24VAC across pins 6 & 7 on header H1 for the NWB
to operate. If there is 24VAC across pins 6 & 7 and the
LED is a constant off, the NWB will need to be
replaced.
The FEC must supply 5 VDC to the NWB via pins 1 &
2 on H1 for the NWB to function correctly. If the
5VDC is not present, the NWB can in no way
communicate with the FEC. If this voltage is not
present, the harness or the FEC may be at fault.
LED is Flashing Rapidly or is Constantly On - If
the LED is constantly on or is flashing rapidly or
erratically, the NWB may be in a lock-up state or may
be bad. Remove power from the board by pulling
header H1, and then put the header back again. If the
LED begins to flash one second on / one second off, the
board is probably OK. If this does not happen, the
NWB will need to be replaced.
If there is 5VDC across pins 1 & 2 of H1 and the NWB
will not communicate with the FEC, swap the harness
between the FEC and NWB with an known good
harness. If this fixes the problem, the harness is at
fault.
LED Flashes Rapidly 3 Times - This sequence
indicates the beginning or end of a communication
sequence with the FEC. The service personnel may
determine if the NWB is communicating with the FEC
by following the procedure in the following section.
If the harness is not at fault, the NWB should be
swapped with a known good board. If this fixes the
problem, the NWB needs to be replaced. If after
changing out the NWB and the harness with known
good samples the NWB will not communicate with the
FEC, the FEC must be at fault.
In general, there are three possible sources of failure,
the NWB, the FEC, and the Harness. Parts may need
to be swapped out individually to isolate the problem.

Troubleshooting
Network Board Blocks Card Reader
Network Board to PC
Communications to FEC - Some failure modes may
prevent the card reader (if connected) to communicate
with the FEC. If this is the case, the NWB itself may
or may not be able to communicate with the FEC.
Communication Problems
Communication between the NWB and the PC may be
interrupted via several cases:
To eliminate the possibility of a bad reader, it is helpful
to temporarily eliminate the NWB from the circuit.
Unplug the harness from the NWB to the card reader,
and also unplug the harness from the NWB to the FEC.
Next, connect the harness which is used to connect a
card reader directly to the FEC.
• NWB not operating correctly (not executing
program)
• NWB cannot communicate with FEC (NWB cannot
get its correct node number)
• Problems on network external to the NWB under test
- Wires flipped at one or more points on the Network
- Short on the Network
NOTE: This harness is not included in machines
containing a NWB, the individual performing the
service to the machine will have to have this
harness.
- Noise on the Network (another node jabbering,
reflections, etc.)
Once the card reader is linked directly to the FEC, wait
15 seconds, and insert any card into the reader. The
FEC display should change to reflect the card insertion.
If the FEC does not indicate that a card was inserted,
the NWB may not be the problem. In this case, see the
section on Card Readers.
NWB Not Operating Correctly - If the NWB is not
executing the code in the processor correctly, there is
no way it can communicate with the FEC. Use the
network board operating LED test and the network
board communicating LED test to verify operation.
NWB Cannot Get Node Number From PC - If this is
the case, the PC should be able to communicate with
the NWB by attempting to communicate with node
250. Note that since 250 is the default node in the
NWB, if it cannot retrieve another node number from
the FEC, it will default to 250. When running this test,
remember that there may be other nodes on the
network, due to other failures, that may result in more
than one node 250 on the network. If this is the case,
the PC may not be able to get through to any node
numbered 250. Because of this, it is desirable, if
possible, to perform this test on a “1-node” network,
which contains only the NWB under test.
If the card reader does communicate the card insertion
to the FEC, remove the temporary harness and put the
original harnesses back in place, so that the NWB is
once again in the circuit.
Next, swap the harness from the NWB to the card
reader with a known good harness. If the reader is now
able to communicate a card insertion, the harness is at
fault, and must be changed. If not, put the original
harness back, and continue.
Check that there is 5 VDC across pins 1 & 2 of H1 on
the NWB. If this voltage is not there, communication
between the FEC and the card reader or NWB will not
occur.
If the PC can communicate with the NWB as node 250,
then either the FEC has node number 250 programmed
into it (test via the Microwand), or the NWB is not
communicating with the FEC. Use the network board
communicating LED test to verify operation.
If there is 5VDC across pins 1 & 2 of H1 and the card
reader cannot communicate with the FEC, swap the
harness between the FEC and NWB with an known
good harness. If this fixes the problem, the harness is
at fault.
Problems Related to Network - If possible, it may be
beneficial to isolate the NWB in question from the rest
of the network, creating a “1-node” network. This
eliminates other network boards, mis-wiring on the
network, etc., as causes for a NWB not communicating
with the PC.
If the harness is not at fault, the NWB should be
swapped with a known good board. If this fixes the
problem, the NWB needs to be replaced. If after
changing out the NWB and the harness with known-
good samples the card reader cannot communicate with
the FEC, the FEC must be at fault.
With the NWB alone connected to the PC, attempt to
communicate with the board. If no communication
occurs at any node number, the NWB or the harness
from the NWB to the connector at the rear of the
machine is bad. Try swapping the NW cable from the
rear connector to the NWB and test again. If
communication is successful, the harness needs to be
replaced.
