Wire The Circuit Boards
|
NOTICE: You must install the Main (JAMMA) Wiring Harness supplied with this conversion kit. This VGM's 49-way joysticks require wires and circuits not found in earlier VGMs. If the connectors in your cabinet don't fit onto the CPU Board or wire colors don't match the JAMMA Chart, contact your authorized distributor for assistance. | |

CAUTION: Insulate unused wires within the JAMMA cable, especially red, yellow, orange and black power wires. Secure unused connectors away from the CPU Board and its cover. |

CAUTION: ATTACH CONNECTORS PROPERLY. Be sure that printed circuit board (PCB) connectors mate properly. If connectors don't slip on easily, don't force them. A reversed connector may damage your VGM and void the warranty. Connector keys allow a connector to fit only one set of pins on a board. |
[ ] 1. Connect the shielded video cable between Video Board jack J4 and CPU Board plug P4. Your video monitor requires either positive or negative sync. If necessary, add or remove the video sync jumper at SIO Board jumper block J2. The default mode is positive sync (no jumper between pins 1 and 2). For negative sync, jump pins 1 and 2.
[ ] 3. The disk drive power cable includes three plugs for the fans. Connect these plugs to the fans.
[ ] 4. Secure hard disk drive and fan cables with three cable clamps from the kit. Attach the cable clamps to standoffs at three corners of the SIO Board. Use the board's mounting screws to fasten the clamps to the standoffs: Position the first clamp near the SIO Board's large heatsink. Position the second clamp directly across from the first, near the Auxiliary Adapter Board. Position the third clamp near the hard drive.
[ ] 5. Locate the hard drive data cable, a ribbon cable. Orient the data cable connector over CPU Board plug P5. Align the connector's striped edge with Pin 1, near the video connector. (The stripe may be red, blue or another color.) Mate the connector halves. Press them firmly to seat contacts.
[ ] 6. Connect the Main Harness to the SIO Board edge (JAMMA). This cable has wires for the coin door, control buttons, I-40 Joystick Interface Board, speakers, video monitor, power supply, and so forth. Insulate and secure all extra wires (unused slam tilt switch, coin meter, etc.).
[ ] 7. Search through the Main Harness for the Player 4 and Player 3 cables. Player 4 has gray wires with stripes. Player 3 has blue wires with colored stripes. Connect Player 3's plug to SIO Board jack P14, and Player 4's plug to P7.
[ ] 8. Find the coin door power connector. (Look for the black, red and orange wire bundle.) Attach this connector to plug P23 on the SIO Board.
[ ] 9. Search through the Main Harness for the six-pin monitor connector. Plug this into your monitor.
[ ] 10. Connect the Main Harness to the Aux Out Adapter Board at connector P1.
[ ] 11. Connect the 20-pin ribbon cable to the Aux Out Adapter Board at jack P1. Connect the other end of this ribbon cable to SIO Board at jack P15.
