   Controls system I/O, handles internal bus communication, and supports Genius bus I/O with watchdog protection.
4. Error & Alarm Handling

   Monitors system health, logs alarms, and triggers safety interlocks.

4. Compatibility

• Compatible With:

  • YASNAC LX / MX CNC systems

  • Motoman ERC robot controllers (early firmware)

  • JANCD-SP series display/interface boards (SP17B/SP20/SP21)

• Incompatible With:

  • XRC, NX100, DX, YRC series robot controllers

  • Later CPU boards (e.g., JANCD-SR21)

5. Installation & Maintenance

Installation

1. Power off the controller and wait ≥5 minutes for discharge.

2. Use anti-static protection (wrist strap).

3. Align and insert into the designated backplane slot; secure screws.

4. Reconnect all cables and power on.

Troubleshooting

• No boot / black screen: Check +5 V power, reseat the board, clean edge connectors.

• Persistent alarms: Verify firmware compatibility; check for damaged components.

• Communication errors: Inspect backplane and ribbon cables; reseat adjacent boards.

Safety Notes

• Always power off before removal/installation.

• Handle only with anti-static precautions.

• Keep board clean and dry; avoid corrosive environments.
