3. Instrucciones de funcionamiento
3.1 Transmisión transparente
The E30-170T20D module supports transparent transmission, meaning data sent to its UART input (RXD) will be wirelessly transmitted, and data received wirelessly will be output through its UART output (TXD). This simplifies integration as no complex protocol handling is required at the host microcontroller level for basic data transfer.
3.2 Air Wake-up Function (WOR)
The module features a WOR function, enabling ultra-low power consumption. In WOR mode, the module can periodically wake up to check for incoming data, and if no data is detected, it returns to a low-power sleep state. This is ideal for battery-powered applications where energy efficiency is critical.
3.3 Forward Error Correction (FEC)
The integrated FEC algorithm enhances the reliability and transmission range of the module. FEC proactively corrects interfered data packets, reducing data loss in environments with sudden interference. Without FEC, such packets would typically be dropped, leading to reduced data integrity and effective range.
3.4 Data Rate and Half-Duplex Operation
The module supports air data rates ranging from 1kbps to 25kbps. It operates in half-duplex mode, meaning it can either transmit or receive data at any given time, but not simultaneously. Proper communication protocols should account for this half-duplex nature to manage data flow effectively.
4. Mantenimiento
4.1 Cuidados generales
- Mantenga el módulo limpio y libre de polvo y residuos.
- Avoid exposing the module to extreme temperatures or humidity outside its specified operating range.
- Ensure proper ventilation if the module is enclosed to prevent overheating.
4.2 Precauciones de descarga electrostática (ESD)
The E30-170T20D is an ESD sensitive device. Always handle the module with appropriate ESD precautions, such as using an anti-static wrist strap and working on an ESD-safe mat, to prevent damage to internal components.
4.3 Entorno operativo
The module is designed for industrial-grade applications and can operate reliably in temperatures ranging from -40 °C to 85 °C. While robust, prolonged exposure to the extreme ends of this range or rapid temperature changes should be minimized to ensure longevity.
5. Solución de problemas
5.1 No Communication
- Verifique la fuente de alimentación: Verify that the VCC pin receives a stable voltage within the 2.3V to 5.2V range.
- Conexiones UART: Ensure TXD and RXD pins are correctly connected to your host device (TX to RX, RX to TX).
- Velocidad en baudios: Confirm that the UART baud rate and other serial parameters (data bits, parity, stop bits) match between the module and your host device.
- Modo módulo: Check the M0 and M1 pin states to ensure the module is in the correct operating mode for communication.
5.2 Poor Range or Signal Quality
- Antena: Ensure the antenna is securely connected to the SMA port and is appropriate for the 170MHz frequency band.
- Obstrucciones: Minimize physical obstructions (walls, metal objects) between the transmitting and receiving modules.
- Interferencia: Identify and mitigate potential sources of RF interference in the operating environment.
- Potencia de salida: Verify the module's power output settings. Higher power generally provides better range, but ensure compliance with local regulations.
5.3 Module Not Responding
- Reset: Intente apagar y encender nuevamente el módulo.
- Daño: Inspeccione el módulo para detectar cualquier daño físico visible.
- EDS: Consider if the module might have been exposed to electrostatic discharge without proper precautions.
