3.1 conectores

• DB9 Male (M): 9-pin D-sub male connector.
• DB9 Female (F): 9-pin D-sub female connector.
• DB25 Male (M): 25-pin D-sub male connector.
• DB25 Female (F): 25-pin D-sub female connector.

3.2 Indicadores LED

The module features 8 dual-color LEDs, each corresponding to a specific RS-232 signal line. These LEDs illuminate green for a logic HIGH state and red for a logic LOW state. The monitored signals include:

• DCD (Detección de portador de datos)
• RXD (Receive Data)
• TXD (transmisión de datos)
• DTR (Terminal de datos listo)
• DSR (Conjunto de datos listo)
• RTS (Solicitud de envío)
• CTS (listo para enviar)
• RI (Ring Indicator)

3.3 interruptores DIP

A 9-position DIP switch allows for individual control over each signal line. Moving a switch to the 'ON' position connects the corresponding signal, while moving it to the 'OFF' position disconnects it. This feature is useful for isolating specific signals during testing purposes.

4. Configuración y conexión

1. Identificar conectores: Determine the appropriate DB9 or DB25 male/female connectors on the tester that match your RS-232 serial link.
2. In-line Connection: Connect the OONO F-1068 module in series with the RS-232 data link you wish to test. One connector will serve as the input (Master), and another as the output (Slave).
3. No External Power: The module operates without external power. It draws necessary power from the RS-232 line.
4. No Drivers: No software drivers are required for operation. The device is plug-and-play.
5. Adjusting Jack Sockets (Optional): If your existing cables have jack sockets that interfere with the tester's connectors, the jack sockets (nuts) on the tester can be unscrewed to ensure a proper mate.

5. Instrucciones de funcionamiento

5.1 Monitoring Signal States with LEDs

Once connected, the 8 dual-color LEDs will immediately display the logic states of the respective RS-232 data lines. Observe the LEDs to understand the signal activity:

• LED verde: Indicates a logic HIGH state for the corresponding signal line.
• LED rojo: Indicates a logic LOW state for the corresponding signal line.
• LED parpadeantes: Rapid changes between red and green (or on/off) indicate active data transmission on that line.

5.2 Using the DIP Switch

The 9-position DIP switch allows you to individually control the connection of each signal line. Moving a switch to the 'ON' position connects the corresponding signal, while moving it to the 'OFF' position disconnects it. This feature is useful for isolating specific signals during troubleshooting.

6. Typical Application Scenarios

The OONO F-1068 is an invaluable tool for various RS-232 diagnostic tasks:

• Data Flow Monitoring: Observe TXD and RXD LEDs to determine data transfer direction (e.g., from machine to computer or vice versa).
• Verificación de cables: Verify if TXD/RXD wires are correctly wired (crossed vs. straight-through cable) by observing their LED states at rest.
• DTE/DCE Device Identification: Determine if a connected device is Data Terminal Equipment (DTE) or Data Communication Equipment (DCE) and if a null modem is required.
• Modem Control Signal Status: Check if modem control signals are active, even if they are not being asserted.
• Control System Testing: Test control signals between control systems (e.g., AMX) and the devices they manage.
• Connection Integrity Check: Confirm proper serial connection mating and active communication.
• Fault Isolation: Aid in determining whether a wall control, projector, or other serial device is malfunctioning.

7. Compatibilidad del sistema operativo

As a hardware diagnostic tool, the OONO F-1068 does not require specific operating system drivers. It is compatible with any system utilizing RS-232 serial communication, including but not limited to:

• Windows 98, Me, XP, 2000, 2003, CE, Vista, 7, 8
• Linux
• Mac OS 10.X and later

8. Guía de solución de problemas

The OONO F-1068 is primarily a troubleshooting tool itself. The following points guide you on how to interpret its indications to diagnose common RS-232 issues:

• Sin actividad LED:
  • Ensure the module is correctly connected in series.
  • Verify that the connected devices are powered on and attempting to communicate.
  • Check the integrity of the RS-232 cables.
  • Confirm that the DIP switches are in the 'ON' position for the signals you expect to monitor.
• TXD/RXD LEDs Not Flashing During Data Transfer:
  • Confirm that data is actively being sent by the transmitting device.
  • Check for correct pinout (crossed vs. straight-through cable). If TXD from one device should connect to RXD of another, and vice-versa, ensure the cable facilitates this.
  • Use the DIP switches to isolate TXD and RXD lines to confirm their individual activity.
• Unexpected LED States (e.g., DTR/DSR always LOW):
  • This may indicate a device is not ready or a control signal is not being asserted.
  • Consult the documentation for the connected DTE/DCE devices to understand their expected control signal behavior.
• Comunicación intermitente:
  • Look for intermittent flashing or changes in LED states, which might indicate loose connections or signal integrity issues.
  • Asegúrese de que todos los conectores estén bien sujetos.
