This illustrates how the gateway connects to an Ethernet network (router), RS-232 controlled devices (projector), IR emitters/blasters (Blu-ray players), GPI/O sensors, and relay-controlled devices (screen), allowing control from iOS/Android devices.
5. Configuración
5.1 Instalación física
The FC-28 is designed for flexible placement. Ensure the chosen location allows for adequate ventilation and easy access to ports.
- Coloque la unidad sobre una superficie plana y estable.
- If rack-mounting or surface-mounting, use the appropriate Kramer mounting accessories (sold separately or included with specific kits) and follow their installation instructions.
5.2 Conexión de alimentación (PoE)
The FC-28 is powered via Power over Ethernet (PoE).
- Connect an Ethernet cable from a PoE-enabled network switch or injector to the Ethernet port on the FC-28.
- The unit will power on automatically once a valid PoE connection is established. Verify the power indicator LED on the unit illuminates.
5.3 Conexión de red
The Ethernet port also provides network connectivity for control and configuration.
- Ensure the Ethernet cable from the PoE source is connected to your network.
- The FC-28 will obtain an IP address via DHCP by default. Refer to the Kramer control software or network tools for device discovery and static IP configuration if required.
5.4 Connecting Control Devices
Connect your target devices to the appropriate ports on the FC-28.
- Serial (RS-232) Ports: Connect RS-232 controlled devices (e.g., projectors, displays) using standard serial cables.
- Puertos de infrarrojos: Connect Kramer IR emitters or blasters to control IR-enabled devices (e.g., Blu-ray players, media players).
- GPI/O Ports: Connect sensors, buttons, or other General Purpose Input/Output devices.
- Relay Ports: Connect devices that require simple contact closure control (e.g., projector screens, blinds).
6. Instrucciones de funcionamiento
The Kramer FC-28 is primarily controlled and configured via a network connection using Kramer's control software or API commands.
6.1 Configuración inicial
Upon initial power-up and network connection, the FC-28 is ready for configuration.
- Use Kramer's network discovery tools or a web browser (if a web interface is available) to locate the FC-28 on your network.
- Access the device's configuration interface to assign static IP addresses, configure port settings (baud rates for serial, IR codes, GPI/O functions, relay states), and integrate with your control system.
6.2 Control Integration
Once configured, the FC-28 acts as a bridge between your control system and the connected devices.
- Integrate the FC-28 into your preferred control platform (e.g., Kramer Control, third-party control systems) using its API or drivers.
- Send commands through the network to the FC-28, which then translates and transmits them via the appropriate Serial, IR, GPI/O, or Relay port to control the end devices.
7. Mantenimiento
Regular maintenance ensures optimal performance and longevity of your FC-28.
- Limpieza: Utilice un paño suave y seco para limpiar el exterior de la unidad. No utilice limpiadores líquidos ni en aerosol.
- Actualizaciones de firmware: Revise periódicamente el Kramer website for firmware updates. Follow the provided instructions carefully for any updates to ensure compatibility and access to new features.
- Ventilación: Asegúrese de que las aberturas de ventilación no estén obstruidas para evitar el sobrecalentamiento.
8. Solución de problemas
If you encounter issues with your Kramer FC-28, refer to the following common problems and solutions:
| Problema | Posible causa | Solución |
|---|---|---|
| La unidad no se enciende. | No hay conexión PoE o fuente PoE defectuosa. | Verify the Ethernet cable is securely connected to a PoE-enabled port. Check the PoE switch/injector for proper operation. |
| Cannot discover the unit on the network. | Network connectivity issue, incorrect IP settings, or firewall. | Ensure the Ethernet cable is connected. Check network settings (DHCP server, subnet). Temporarily disable firewalls for testing. Use Kramer's discovery tools. |
| Connected device is not responding to commands. | Incorrect port configuration, faulty cable, or device issue. | Verify port settings (baud rate, IR codes) in the FC-28 configuration. Check the cable connection to the controlled device. Ensure the controlled device is powered on and functioning correctly. |
| Control intermitente. | Network interference or loose connections. | Check for network congestion or interference. Ensure all cables are securely connected. |
If the problem persists, contact Kramer technical support for further assistance.
