Troubleshooting

Playbook to shoot troubles

  1. LED does not blink on power-on
    1. Do you supply 5V power via power supply USB port correctly?
      • Supply 5V power.
    2. Don’t you press SERVICE button on boot.
      • Do not press SERVICE button on booting.
    3. Did you fail firmware update?
      • You can retry firmware updates even if the written firmware is broken. Follow the steps described in the Firmware Update page.
    4. Continue blinking 3 times
      • This is a caution that you didn’t store layout settings for v2 firmware.
    5. Other cases.
      • The device may get broken during or after shipping. Feel free to contact the author.
  2. JVS based systems don’t recognize IONA-US.
    1. Do you connect IONA’s JVS port to the JVS system correctly?
      • Connect them for JVS bus with a general USB cable.
    2. Are jumpper pins for firmware updates shorten?
      • As it makes JVS but not to work, please open these pins.
    3. Are LED blinking or off?
      • It should blink after the initial boot, blink fastly on JVS but reset, turn on when an address is assigned over JVS. Unless an address is assigned, it should not be recognized. As this may be a compatibility issue, feel free to contact author with LED status.
      • Try with JVS signal level adjustment option to be enabled or disabled. Some system board has a compatibility issue, and works with one of these modes. You can flip the mode by making it power-on while pressing the TEST button.
    4. Other cases.
      • Do you use a firmware version that supports your PCB version?
      • May be a compatibility issue for IONA-US and the arcade system board.
      • Try with the JVS signal level adjustment disabled in the option mode config. It may be resolved by a firmware update if you report the issue. If the title is not listed at Compatibility Information, it’s just unsupported. If it is, there may be an electrical compatibility issue. Etherway, firmware update may be able to solve the issue if you report.

      • If you enter any configuration mode by pressing TEST+SERVICE, inputs from gamepad are not sent to the system board over JVS. Please quit the setting mode.
    3. Do you see LED flash on connecting the USB gamepad?
      • It doesn’t flash if the gamepad is not recognized in confidence. It wouldn’t be an officially supported device. Feel free to request the device support at the Report page with informatino for the device.
    4. Do you configure custom layout correctly?
