Maintenance

  • Routine inspection: Check module LED status, RJ45 connector and serial cable integrity every 6–12 months
  • Clean dust on module surface with dry compressed air; liquid solvent cleaning is strictly prohibited
  • ESD protection must be adopted during disassembly, anti-static wristband required
  • When serial communication failure occurs, verify baud rate, station address, wiring and shielding grounding
  • Do not energize 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. Hot-swap replacement can be performed following system safety procedure or cut off cabinet power supply.
  2. Wear anti-static wristband to prevent electrostatic damage to PCB components.
  3. Insert CI853 module into the designated CEX bus slot of AC800M rack, lock the fastening latch.
  4. Connect RS232 serial cables to RJ45 ports, ensure proper cable shielding and grounding.
  5. Configure communication protocol, baud rate and station address via control engineering 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.
