• **DC Power:** Connect a 7-36V DC power supply to the V+ and GND terminals on the module. Observe polarity.
• **PoE Power:** Connect an Ethernet cable from a PoE-enabled switch or injector to the Ethernet port on the module. The module supports 802.3af standard PoE.
• **USB-C Power (for development/testing):** A USB-C cable can also supply power for development or testing purposes, but it is not recommended for permanent industrial installations.

4.3 Veze sučelja

Refer to the pinout diagram (Figure 3.1) for detailed terminal assignments.

• **Relay Outputs (CH1-CH8):** Each relay provides Normally Open (NO), Common (COM), and Normally Closed (NC) contacts. Connect your loads (e.g., lights, motors) to the appropriate contacts. Ensure the load's voltage and current ratings do not exceed the relay's specifications.
• **Digital Inputs (DI0-DI7):** Connect external switches or sensors to the digital input terminals and the common (COM) terminal. These inputs are isolated for industrial reliability.
• **CAN Interface:** Connect CAN_H, CAN_L, and CAN_GND to your CAN bus network. The interface is isolated.
• **RS485 Interface:** Connect RS485_A, RS485_B, and RS485_GND to your RS485 network. The interface is isolated.
• **Ethernet:** Connect a standard RJ45 Ethernet cable for wired network communication.

5. Upute za rad

The ESP32-S3 module requires custom firmware for specific applications. This section outlines general operational aspects.

5.1 Početno uključivanje

Once power is supplied (via DC or PoE), the Power indicator LED will illuminate. The ESP32-S3 status LED will indicate the module's operational state, typically blinking during boot-up and remaining solid or blinking according to the loaded firmware's logic.

5.2 Firmware Development and Upload

The module is programmable using the ESP-IDF framework or Arduino IDE. Connect the module to your computer via the USB-C port for programming. Use the BOOT button in conjunction with the RESET button to enter bootloader mode for firmware uploads.

• **RESET Button:** Press to restart the ESP32-S3.
• **BOOT Button:** Hold down the BOOT button while pressing and releasing RESET to enter firmware upload mode.

5.3 Mrežna komunikacija

• **Wi-Fi:** Configure Wi-Fi credentials within your custom firmware to connect to a local wireless network. The external antenna enhances Wi-Fi range and stability.
• **Ethernet:** If using wired Ethernet, ensure your network provides DHCP or configure static IP settings in your firmware. The Ethernet status LEDs will indicate link activity and data transmission.
• **Bluetooth:** Utilize Bluetooth 5 (LE) for short-range communication as defined by your application's firmware.

5.4 Relay and Digital Input Control

The control logic for the 8 relays and reading of the 8 digital inputs is entirely dependent on the firmware you develop and upload to the ESP32-S3. The isolated interfaces ensure protection against electrical noise and ground loops in industrial environments.

6. Održavanje

The ESP32-S3-POE-ETH-8DI-8RO-C module is designed for industrial environments and requires minimal maintenance. However, periodic checks are recommended:

• **Environmental Conditions:** Ensure the module operates within its specified temperature and humidity ranges. Avoid exposure to excessive dust, moisture, or corrosive substances.
• **Firmware Updates:** Regularly check the Waveshare Wiki for firmware updates or security patches for the ESP32-S3 platform. Update your custom firmware as needed to incorporate improvements or address vulnerabilities.
• **Connection Integrity:** Periodically inspect all wiring connections (power, relays, digital inputs, CAN, RS485, Ethernet) to ensure they are secure and free from corrosion or damage.
• **Cleaning:** If necessary, gently clean the exterior of the module with a soft, dry cloth. Do not use liquid cleaners or solvents.

7. Rješavanje problema

If you encounter issues with your module, consider the following troubleshooting steps:

• **Module Not Powering On:**
  • Verify the 7-36V DC power supply is correctly connected and providing the correct voltage.
  • If using PoE, ensure your Ethernet switch/injector is PoE-enabled and functioning correctly.
  • Check the USB-C connection if powering via USB.
  • Ensure the Power indicator LED is illuminated.
• **Wi-Fi/Ethernet Connectivity Issues:**
  • Ensure the 2.4G antenna is securely connected.
  • Verify Wi-Fi credentials and network availability in your firmware.
  • For Ethernet, check the cable connection and the status of the Ethernet LEDs. Confirm network settings (DHCP/static IP) in your firmware.
  • Ensure no IP address conflicts on your network.
• **Relays Not Actuating:**
  • Check your firmware logic to ensure the relays are being commanded correctly.
  • Verify the power supply to the module is stable.
  • Inspect wiring to the loads and ensure they are within the relay's voltagograničenja e/struje.

• **Digital Inputs Not Responding:**
  • Check the wiring from your sensors/switches to the digital input terminals and COM.
  • Verify your firmware is correctly reading the digital input states.
  • Ensure the external signals are within the acceptable voltage range for the isolated inputs.
• **CAN/RS485 Communication Failure:**
  • Verify correct wiring (H/L for CAN, A/B for RS485) and termination resistors if required by your bus.
  • Check the CAN TX/RX and RS485 TX/RX indicator LEDs for activity.
  • Ensure your firmware is correctly configured for the bus speed and protocol.
• **Firmware Upload Issues:**
  • Ensure the USB-C cable is a data-capable cable, not just a charging cable.
  • Confirm correct driver installation for the USB-to-serial converter.
  • Follow the correct procedure for entering bootloader mode (hold BOOT, press/release RESET).
