Maintenance

  • Routine inspection: Check module LED status, RJ45 connector and serial cable condition every 6–12 months
  • Clean dust on module surface with dry compressed air; liquid solvent cleaning is prohibited
  • ESD protection must be adopted during disassembly, anti-static wristband required
  • When serial communication interruption occurs, check baud rate, station address, cable wiring and grounding
  • Do not power on the module if PCB corrosion, burn marks or condensation are found
  • We support function testing, refurbishment and spare replacement service for this serial communication module

 

Installation

  1. Can perform hot-swap replacement following system safety procedure or cut off cabinet power supply.
  2. Wear anti-static wristband to prevent electrostatic damage to PCB components.
  3. Insert CI853K01 module into the designated CEX bus slot of AC800M rack, lock the fastening latch.
  4. Connect RS232 serial cables to RJ45 ports, ensure cable shielding and grounding properly.
  5. Configure communication protocol, baud rate and station address via control software.
  6. Check all connections and confirm no loose wiring inside cabinet.
  7. Restore power supply, download controller configuration.
  8. Verify serial communication status, test data exchange with field serial devices and complete commissioning.
