IMPORTANT NOTES & INFORMATION:
*CAUTION* JAYPRO RECOMMENDS ALL WORK TOBE COMPLETED BY A QUALIFIED ELECTRICIAN. ACCESSING THE MEC2
RELAY PANELS INTRODUCES ELECTRICAL HAZARDS AND CAUTION MUST BE TAKENTO PREVENT INJURY OR DAMAGE TO
THE EQUIPMENT.
1. It is theElectrician's responsibilityto ensurethe relays havebeen programmed properly.
2. It is theDealer's responsibility to ensurethe customer has been properlytrained on the MEC2 system.
3. Beforeany work outlined in this manual is done on the MEC2 system, the individual completing this workmust have
agood, working knowledge of the MEC2 system. If you arenot familiar with the programming side of the MEC2, do
not complete any work outlined in this manual.
4. It must be verified that the MEC2 touchscreen has been programmed properly beforeany work is completed.
Refer totheMEC2 installationmanual and electrical set-upinstructions for further information.
5. Read this manual in it's entirety and consult Jaypro Sports with any additional questions.
6. Jaypro is not responsiblefor any damage that is done to the MEC2 system when theproper precautions arenot
followed.
MEC2 NOMENCLATURE:
The following is a basic overview of the MEC2 Relay Boards. The system displays a main relay board and an
expansion relay board. Each facility has a it's own configuration which may look different than the one below.

ISSUE #1: TOUCH SCREEN IS NOT COMMUNICATINGTOANY RELAY BOARD
There area fewquick items to check if the touchscreen is not communicating to the mainor expansion relay board.
These items shouldbe checked if none of the relays respondtothe touchscreen. If oneof the relays responds tothe
touchscreen, these following items arenot applicable.
1. Check the Ethernet cable is plugged into the proper port on the back of the touchscreen. There are 2 ports on the
back of the touchscreen. Make sure theEthernet cables arehooked into the proper ports for single/multi-screen
systems.
2. Check the Ethernet cablefor proper wiring convention. The Ethernet cablemust utilize astraight-throughEIA568A
or EIA568B wiring convention. The crossover convention is NOT ALLOWEDand may result in damage tothe MEC2
system. It is highly recommended toutilize aLANtester toensure eachRJ45/EZ-RJ45 connector is terminated
properly. See belowfor the proper wiring convention.

3. Check tomakesurethe Ethernet port is properlysecured tothe board. It is possible that the port may pull away
from the board. AVOID REMOVING THE PORT FROM THE BOARD IF POSSIBLE. The pins on the bottom of the port are
extremely delicate and easy to damage.
4. Check to make surebothjumpersonthe Ethernet port havebeen removed. If present, remove anddiscard.
If communication fromthe touchscreen to the relay boards is still an issue, contact JayproSports tofurther
troubleshoot. Be prepared to send photos of the touchscreen and relay enclosures. We will also need to
knowtheproject location, dateof installation, and type/number of devices connectedtothe system.

ISSUE #2: TOUCH SCREEN IS COMMUNICATINGTOSOME RELAYS, BUT NOT ALL
A communication failure to certain relays typically indicates a failureto one of the relay communication chips. The
communication chips are located near the LED relay indicators. These chips can be easily removed and swapped
out. The chips aredelicateandcaremust be taken when removing each chip. Each chip is responsiblefor up to 4
relay pairs (8 individual relays). In other words, the main relay board which has 8 relays pairs contains 2 chips.
*IMPORTANT TO KNOW* Failureof a chipresults inthe NEXT relay set downstreamfromoperating. For example, if the
chip responsiblefor relay pairs 1-4fails (BLUE INCOLOR ABOVE), you will still be abletooperatethe devices wired to
relay pairs 1-4, BUT you will not be able to operate relay pairs 5-8 and beyond (YELLOW IN COLOR). The failure of the
chip prevents communication to the next relay pair set.

ISSUE #2: TOUCH SCREEN IS COMMUNICATINGTOSOME RELAYS, BUT NOT ALL (continued)
1. Todetermine if you have abad chip, the easiest solution is toswap chips between boards. Keep inmindthat the
relay set beyond the failed chip arethe relays sets that areaffected. Beforeremoving andswapping the
communicationchips, the power tothe systemAND to the devices must beturnedOFF. Keepinmind that thereis
LIVE power coming intoeach relay set. Failuretoturn the power results inan electrical hazard!
If communication fromthe touchscreen to the relay boards is still an issue, contact JayproSports to further
troubleshoot. Be prepared tosendphotos of the touchscreen andrelay enclosures. We will alsoneedto
knowtheproject location, dateof installation, andtype/number of devices connectedtothe system.

With thepower turnedoff, usinga small flathead screwdriver
to gently pry off and swap the communication chips. The
chips must be installed in the same orientation they are
removed. You will notice anotch on the top of the chip. This
notch must be aligned with the notch on the relay board, as
shown inthe figure below.
Power on thesystemanddevices andtest. If the chips is
knowntobedefective, thechipshould bereplaced.
Temporarily, the defective chipcan be swapped out with the
farthest downstream relay pair set. Again, the defective chip
only affects the relay set beyond.
EXAMPLE: The image to the right shows a
system with a MAINrelay board and one
EXPANSION relay board. Imaging that relay
pairs 5-8 on the main boardand 1-4 on the
expansion board do not operate. This
indicates that the communication chipfor
relay pairs 1-4 on the main relay board has
failed. By swapping out the communication
chip for relay pairs 1-4 on the main board
with the communication chipon the
expansion board, all relays should operate
as intended. However, if another expansion
boardis connected at another point in
time, communicationtothat board will not
be possibleuntil thecommunicationchip is
replaced.
