General view
DIP switch and indication description
On PCB MJ –5 there are following indication elements (see General view …)
-
LD1 —reset indication
-
LD2 —indication of work state
-
LD3 —indication +5V
-
LD4 —indication +3.3V
-
LD5 —indication +2.5V
-
LD6 —indication of coefficient for channel COIN IN Ax
-
CONN1 — connector inputs/outputs
-
P7 — connector for billaceptor
-
P4 — RS-485 interface. For Jackpot Network.
Driving elements
-
DIPSW1 — coefficient setup for channel COIN IN Ax
-
J3 — switch hopper mode.
DIPSW1 set coefficient for Credit per coin. We need this switch to connect two coin selector with different coins or to connect coin selector and bill acceptor (which work in pulse mode). So in this case there is additional channel COIN IN Ax.
LD6 indicate coefficient value of COIN IN Ax after switch on or after reset.
Jumper J3 switch hopper mode.
Position 1-2 - if hopper can not be driven by logic signal. Only by voltage.
Position 2-3 - if hopper can be driven by logic signal. For switch on Hopper logical level should be Low.
This mode is used when we connect “minus” of the hopper.

PCB power supply
Some instruction describe game MEGAJACK, and can be some difference with another games.
PCB MJ-5 should have stabilized voltage +12V. If power supply will be lower +9V, PCB does not start.
After switch on LD1 and LD2 is light. Then after 3 sec LD1 (red) does not light. Then after 15 sec LD2 (green) does not light. If LD2 is light - low voltage.
After game start the buttons will work after 15 sec (same delay will be after go out from test pages).
PCB MJ-5 should have stabilized voltage +12V. To stabilize voltage you should put resistor:
For AT power supply and for WY-03C (from Taivan) you should load +5V
For ATX power supply you should load +3.3V (See picture 1).
If you does not make it can happen following:
Line 12V can be different than +12V. Player press “Start” and in some period time picture on the screen is stopped or button does not work. Description: After pressing “START” lamps is light on, current is grow and voltage goes down. Special schematic stop work till normal voltage (in this case incorrect data can not be saved in memory).

Hopper connection
MJ- 5 have two hopper mode (Jumper J3). See picture 2 and 3.
In position 1-2 hopper start after sending +12V.
On the picture 4 there is example of connection “CUBE HOPPER MK II” without external driver.

Coinselector and billacceptor
Coinselector is connected to A13 (COIN IN) or A16 (COIN IN Ax) on connector CON1.
On A13 you receive credit according to option Credit per coin .
On A16 you receive credit according to option Credit per coin multiplying on coefficient (coefficient is set up by DIP switch DIPSW1 - see Table 3).

Speaker connection
Before switch on PCB you should check following:
Speaker should be connected to A19 and B19 (Connector CON1) not A19 and GND. See picture 7.

Jackpot Network
(Now work only with game Megajack on PCB MJ-5 and another PCBs: company JAM, Master Games, Alfa Base)
Connection between PCBs and Jackpot controller work through RS-485 interface (In Ukraine we call it 27 line). The game MegaJack have name in the network Cherry7. PCB connect to network through connector P4. For work in the JACKPOT chip U2 (MAX1480BCPI) should be set on PCB (See General view). To set number in Jackpot network you should open EEPROM STATISTICS: Option Network Jackpot Node value should be 1..14. In the PREF select Credits and bets and set up Credit payout = Payout button only. Set up option Credit per bill = 100 (can be other value, depend of credit price). When PCB work in the Jackpot network you should not use Bill acceptor in parallel mode. All jackpot which PCB receive will be in BILL IN statistics.
