4.3 Kabelverbindungen
The SK509 module features terminal blocks for power input, signal inputs, and control outputs. Refer to Figure 2 and Figure 3 for the layout and pin assignments.
Abbildung 2: Oben view of the SK509 module, highlighting the terminal blocks and DIP switches.
- Leistungsaufnahme: Connect your 9V-30V DC power supply to the VCC and GND terminals. Observe correct polarity.
- Signal Inputs (IN1-IN4): These terminals are for connecting external trigger signals or sensors. Each input has a corresponding GND terminal.
- Control Outputs (OUT1-OUT4): These terminals provide the control signals for external devices. The specific output type (e.g., relay contact, voltage output) should be confirmed with the detailed product specifications or datasheet.
- NC (No Connection): These terminals are not used.
4.4 Konfiguration der DIP-Schalter
The SK509 module includes an 8-position DIP switch for configuring various operational parameters, including channel selection and operating mode. Refer to Figure 3 for the DIP switch layout and functions.
Abbildung 3: Ausführlich view of the SK509 module label, showing DIP switch functions and terminal labels.
| Schalten | AUS-Stellung | EIN-Stellung | Funktion |
|---|---|---|---|
| 1-4 | Variiert | Variiert | Channel Selection (16 groups) |
| 5 | AUS | ON | Set (Normal) |
| 6 | AUS | ON | Code (Normal) |
| 7 | Sklave | Master | Master/Slave Mode Selection |
| 8 | Timing | Echtzeit | Timing/Real-time Mode Selection |
Channel Selection (Switches 1-4): These switches are used to select one of 16 available wireless channels. The specific combination for each channel can be found in the detailed product datasheet. Ensure that all modules intended to communicate with each other are set to the same channel.
Set (Switch 5): This switch is typically used to enter or exit a configuration mode. When set to 'OFF', it usually indicates normal operation. Consult the datasheet for specific 'Set' mode functionalities.
Code (Switch 6): This switch may relate to pairing or coding functions. In 'OFF' position, it generally indicates normal operation. Refer to the datasheet for detailed coding procedures.
Master/Slave Mode (Switch 7): This switch determines if the module operates as a 'Master' (initiating commands) or 'Slave' (responding to commands) in a multi-module setup. Configure one module as Master and others as Slave for coordinated operation.
Timing/Real-time Mode (Switch 8): This switch selects between 'Timing' mode (where operations occur at predefined intervals or durations) and 'Real-time' mode (where operations respond immediately to input signals).
4.5 Advanced Parameter Configuration
For more detailed parameter adjustments, such as specific timing settings or advanced network configurations, the module can be connected to a PC via a UART interface. Dedicated PC software or direct UART commands can be used for this purpose. A remote controller (SK509-S) can also be used for wireless parameter modification.
5. Bedienungsanleitung
Once the SK509 modules are properly installed and configured via DIP switches, they are ready for operation. The bidirectional nature allows for both sending control commands and receiving status feedback.
5.1 Basic Wireless Control
- Ensure both the transmitting and receiving SK509 modules are powered on and have their antennas connected.
- Verify that both modules are configured to the same wireless channel using DIP switches 1-4.
- If using Master/Slave mode, ensure one module is set as 'Master' and the other as 'Slave' using DIP switch 7.
- Apply a signal to an input terminal (IN1-IN4) on the transmitting module. This signal will be wirelessly transmitted to the corresponding receiving module.
- The receiving module will then activate its corresponding output terminal (OUT1-OUT4), controlling the connected device.
5.2 Bidirectional Functionality
The bidirectional capability means that not only can a 'Master' module send commands to a 'Slave' module, but the 'Slave' module can also send status or feedback signals back to the 'Master'. This allows for more sophisticated control systems where the status of a remote device can be monitored.
5.3 Real-time Mode
In Real-time mode (DIP switch 8 ON), the module responds immediately to input signals. This mode is suitable for applications requiring instantaneous control, such as direct switching of pumps or valves.
5.4 Timing-Modus
In Timing mode (DIP switch 8 OFF), the module can be configured to activate outputs for specific durations or at scheduled intervals. This mode is useful for automated tasks like irrigation cycles. Specific timing parameters are typically set via PC software or UART commands.

7. Fehlerbehebung
If you encounter issues with your SK509 module, consider the following common troubleshooting steps:
- Kein Strom: Verify that the power supply is connected correctly to the VCC and GND terminals and that it provides the specified voltage (9V-30V DC). Check for loose connections.
- Keine Kommunikation:
- Ensure both modules are set to the same wireless channel using DIP switches 1-4.
- Check that antennas are securely connected to both modules.
- Confirm that one module is configured as 'Master' and the other as 'Slave' if operating in that mode.
- Reduce the distance between modules or clear any obstructions that might be blocking the signal.
- Check for sources of strong electromagnetic interference in the vicinity.
- Falsches Ausgabeverhalten:
- Review the DIP switch settings, especially for 'Set', 'Code', 'Master/Slave', and 'Timing/Real-time' modes, to ensure they match your intended operation.
- Verify the wiring to the input and output terminals.
- If using Timing mode, confirm that the timing parameters are correctly configured via PC software or remote controller.
- Modulüberhitzung: Ensure the module is installed in a location with adequate ventilation. Avoid enclosing it in tightly sealed spaces without proper heat dissipation.
8. Wartung
The G-NiceRF SK509 module is designed for robust operation and requires minimal maintenance. Follow these guidelines to ensure its longevity:
- Sauber halten: Reinigen Sie die Außenseite des Moduls regelmäßig mit einem weichen, trockenen Tuch. Vermeiden Sie die Verwendung von scharfen Chemikalien oder Scheuermitteln.
- Umweltschutz: Ensure the module is protected from excessive moisture, dust, and extreme temperatures outside its specified operating range. If used outdoors, an appropriate waterproof enclosure is recommended.
- Verbindungsintegrität: Occasionally check all wired connections (power, input, output, antenna) to ensure they remain secure and free from corrosion.
- Firmware-Updates: If firmware updates become available, follow the manufacturer's instructions carefully for installation.
