3.3 Connexions de cablejat
Ensure all power is disconnected before making any wiring connections.
3.3.1 Connexió RS-232
Connect your RS-232 device to the DB9 male connector on the TCC-100I. This port supports standard RS-232 signals.
3.3.2 RS-422/485 Connection
Use the plug-in terminal block for RS-422/485 wiring. Refer to the pin assignments below:
| Pin | Descripció | Funció |
|---|---|---|
| Tx+(B) | Transmet dades + | RS-422/485 (4-wire) |
| Tx-(A) | Transmit Data - | RS-422/485 (4-wire) |
| Rx+(B)/Data + | Receive Data + / Data + | RS-422/485 (4-wire) / RS-485 (2-wire) |
| Rx-(A)/Data - | Receive Data - / Data - | RS-422/485 (4-wire) / RS-485 (2-wire) |
| RTS+(B) | Request To Send + | RS-422 (Flow Control) |
| RTS-(A) | Request To Send - | RS-422 (Flow Control) |
| CTS+(B) | Clear To Send + | RS-422 (Flow Control) |
| CTS-(A) | Clear To Send - | RS-422 (Flow Control) |

3.4 Connexió d'alimentació
Connect a 12-48VDC power source to the dedicated power input terminal block. Ensure correct polarity (V+ and V-). The PWR LED indicator on the front panel will illuminate when power is successfully applied.
4. Operating the Converter
Once properly installed and powered, the TCC-100I automatically converts serial data between RS-232 and RS-422/485 standards. No software configuration is typically required for basic conversion.
- RS-232 to RS-422 Conversion: Data transmitted via the RS-232 port will be converted to RS-422 differential signals and vice-versa. RTS/CTS signals are also converted for hardware flow control.
- RS-232 to RS-485 Conversion: The converter supports both 2-wire and 4-wire RS-485 modes. Data from RS-232 will be converted to RS-485 differential signals. The TCC-100I features automatic data direction control for RS-485, simplifying setup.
Monitor the PWR LED for power status and the Tx/Rx LEDs (if present) for data transmission activity.
5. Manteniment
The Moxa TCC-100I is designed for low maintenance. However, periodic checks can help ensure its continued reliable operation:
- Neteja: Gently wipe the exterior of the converter with a soft, dry cloth. Do not use liquid cleaners or solvents.
- Connexions de cable: Comproveu periòdicament totes les connexions dels cables per assegurar-vos que estiguin ben fixades i que no estiguin danyats.
- Condicions ambientals: Assegureu-vos que l'entorn de funcionament es mantingui dins dels rangs de temperatura i humitat especificats per evitar danys.
- Actualitzacions de firmware: While typically not required for this type of device, check the Moxa website for any available firmware updates if experiencing unusual behavior.
6. Solució De Problemes
If you encounter issues with your TCC-100I, refer to the following common problems and solutions:
| Problema | Causa possible | Solució |
|---|---|---|
| Sense alimentació (LED PWR apagat) | Sense font d'alimentació, volum incorrectetage, or incorrect polarity. | Verify power supply connection, ensure voltage is within 12-48VDC, and check polarity. |
| Sense transmissió de dades | Incorrect wiring, mismatched baud rates, or faulty cables. | Check RS-232 and RS-422/485 wiring against pin assignments. Ensure baud rates and data formats match between connected devices. Test cables for continuity. |
| Comunicació intermitent | Noise interference, loose connections, or ground loop issues. | Ensure proper grounding. Check for strong electromagnetic interference sources. Verify all connections are secure. The TCC-100I's isolation protection helps mitigate ground loop issues. |
| RS-485 communication issues | Incorrect 2-wire/4-wire setup, missing termination resistors (if applicable to your network). | Confirm the correct RS-485 mode (2-wire or 4-wire) is used. Add termination resistors at the ends of the RS-485 bus if required by your network topology. |
