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  
C866i  
6. Cut an ample length of wire to reach the next  
machines connector. The wire should be long  
enough to move the machine for maintenance,  
but not so long as to interfere with normal  
INCORRECT  
Figure 6  
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.  
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.

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.  
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.  
6. Terminate the last machine on this leg with a  
120 Ohm 1/2 Watt resistor.  
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.  
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.  
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.  
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.  
NOTE: Ensure that only the bias resistors that  
correspond to segment one (PC connection) are  
removed.  
9. Connect the wall adapter to a 120 VAC 60 Hz.

1. Power off all machines before test.  
E. Connecting the Repeater  
to a Laptop  
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 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 Errorsand numerous Unable to  
Connectmessages.  
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  
Errorsand numerous Unable to Connect”  
messages.  
NOTE: Both shorts or flipped wires will cause  
numerous errors on the central PC, including  
Protocol Errorsand numerous Unable to  
Connectmessages.

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 readers 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:26s, the card will  
need to be replaced.  
If a given reader repeatedly gives EC:26s 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:20s are consistently received on an individual  
card, but not on others, the card which gives the errors  
may need to be replaced  
If EC:20s occur often with different cards, the card  
readers 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.

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-nodenetwork,  
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-nodenetwork. 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.
