JVSWatchdog

This repository contains source code for a Windows console application, jvswatchdog.exe, which pings COM2 once per minutes to reset the Taito Type X3 DMAC's watchdog timer, keeping the DMAC from rebooting the Type X3.

The main logic of this was extracted from JoeHowse/KB2FastIO application.

System Requirements

• Operating system: Windows 10 or later. Tested successfully with:
  • Windows 10 Pro, 64-bit
  • Note this may work on other Windows versions but it is untested at this time
• Fast I/O DMAC board and drivers: Tested successfully with:
  • Taito Type X² PCIe board (K91X1209A J9100636A). This device is manufactured by Oki Information Systems and is found in NESiCAxLive and Dariusburst versions of Taito Type X² arcade machines. Device Manager was used to install a driver package containing oem1.inf, iDmacDrv32.sys, and iDmacDrv32.dll, all pulled from a working system.
  • Taito Type X³ PCIe board (K91X1217C J9100638A) + connector board (K92X0281C J9200167C). This device is manufactured by Oki Information Systems and is found in Taito Type X³ arcade machines. Device Manager was used to install a driver package containing idmacdrv64.inf, iDmacDrv64.sys, and iDmacDrv64.dll, iDmacDrv64.cat, and idmacdrv64.PNF, all pulled from a working system.
• Fast I/O microcontroller board: Taito boards with the designation J9100634A (having a JAMMA edge) or J9100633A (not having a JAMMA edge) are believed to be compatible.

Troubleshooting

• General issues:
  • If a COM2 port is present on your system, ensure that it is either unused or connected to a JVS board. If jvswatchdog.exe is able to open COM2, it assumes that COM2 is connected to a JVS board.
