6. Configuració i connexió

This adapter facilitates the connection of an RS485 device to an RJ45 interface. The key is to correctly map the RS485 A and B signals to the appropriate pins on the RJ45 connector.

6.1. RJ45 Pin Mapping for RS485

The adapter supports common RJ45 pin assignments for RS485. The terminal block has two screw terminals labeled 'A' and 'B'.

• Option 1: Using RJ45 Pin 6 and Pin 7
  • Connect the RS485 'A' signal to the terminal labeled 'A'. This typically corresponds to RJ45 Pin 6 (485A).
  • Connect the RS485 'B' signal to the terminal labeled 'B'. This typically corresponds to RJ45 Pin 7 (485B).
  • Nota: Depending on your RS485 device's polarity, you may need to reverse the connections (e.g., terminal A to 485B, terminal B to 485A). The adapter allows for this flexibility as long as the correct two pins are used.
• Option 2: Using RJ45 Pin 4 and Pin 5
  • Connect the RS485 'A' signal to the terminal labeled 'A'. This typically corresponds to RJ45 Pin 4 (485A).
  • Connect the RS485 'B' signal to the terminal labeled 'B'. This typically corresponds to RJ45 Pin 5 (485B).
  • Nota: Similar to Option 1, polarity reversal (terminal A to 485B, terminal B to 485A) is possible if required by your RS485 device.
• Custom Pin Assignments: If your application uses other RJ45 pins for RS485 communication, customization of the wiring may be necessary. Consult your device's documentation for specific pinouts.

6.2. Procediment de connexió

1. Identify the RS485 A and B signals from your RS485 device or network.
2. Loosen the screws on the green terminal block of the adapter.
3. Insert the RS485 'A' wire into the terminal labeled 'A' and tighten the screw securely.
4. Insert the RS485 'B' wire into the terminal labeled 'B' and tighten the screw securely.
5. Plug the RJ45 end of the adapter into the corresponding RJ45 port on your network device or PC, ensuring the RJ45 pins are correctly mapped as per Section 6.1.
6. Verify all connections are firm and correct before powering on any connected equipment.

7. Instruccions de funcionament

The Taidacent RJ45 to RS485 Converter Terminal Adapter is a passive device and does not require external power. Once correctly connected, it acts as a physical interface converter, allowing data to flow between the RJ45 and RS485 interfaces. Ensure that the communication parameters (baud rate, data bits, stop bits, parity) are correctly configured on both the RJ45-connected device and the RS485 device for successful data transmission.

8. Manteniment

This adapter requires minimal maintenance:

• Mantingueu el dispositiu net i lliure de pols. Feu servir un drap suau i sec per netejar-lo.
• Emmagatzemar en un lloc fresc i sec, lluny de la llum solar directa i de temperatures extremes.
• Regularly check connections for tightness, especially in environments with vibration.

9. Solució De Problemes

If you experience issues with the converter, consider the following:

• Sense comunicació:
  • Verify that the RS485 A and B signals are correctly connected to the 'A' and 'B' terminals, respectively, or with reversed polarity if required.
  • Confirm that the RJ45 pins used for RS485 on your network device match the pins connected to the adapter (Pin 4/5 or Pin 6/7).
  • Ensure that the communication parameters (baud rate, data format) are identical on both connected devices.
  • Check for loose connections at both the terminal block and the RJ45 port.
• Comunicació intermitent:
  • Inspect cables for damage or poor shielding.
  • Ensure terminal screws are tightened securely.
  • Check for electromagnetic interference (EMI) in the environment.
