- Do not expose the device to moisture, extreme temperatures, or corrosive substances.
- Älä yritä avata tai muokata laitetta. Jätä kaikki huoltotyöt pätevän henkilöstön tehtäväksi.
Pakkauksen sisältö
Paketin tulisi sisältää seuraava tuote:
- 1 x TRU Components TC-12358892 TC-KW-190 USB to RS485/RS422 Serial Converter
If any items are missing or damaged, please contact your supplier.
Asennus
Follow these steps to set up your USB to RS485/RS422 serial converter:
- Ohjaimen asennus: Before connecting the converter, ensure that the necessary drivers for the FTDI FT232RL chip are installed on your computer's operating system. These drivers are typically available from the FTDI website or your operating system's update service.
- Yhdistä tietokoneeseen: Plug the USB Type-A connector of the converter into an available USB port on your computer. The operating system should detect the new hardware.
- Yhdistä sarjaporttiin: Connect the RS485/RS422 side of the converter to your serial device using appropriate wiring. Refer to your serial device's manual for specific wiring diagrams for RS485 (2-wire or 4-wire) or RS422 connections.
- Tarkista yhteys: After connecting, check your computer's Device Manager (Windows) or equivalent system information (Linux/macOS) to confirm that the converter is recognized and assigned a COM port (Windows) or a serial device identifier.

Käyttöohjeet
Once the converter is successfully installed and recognized by your system, you can use it with serial communication software.
- Valitse COM-portti: Open your preferred serial communication software (e.g., PuTTY, Tera Term, or custom application) and select the COM port assigned to the converter.
- Configure Serial Parameters: Set the serial communication parameters (baud rate, data bits, parity, stop bits, flow control) to match those of your RS485/RS422 device. Incorrect settings will prevent communication.
- Aloita viestintä: Begin sending and receiving data as required by your application. The converter will transparently handle the USB to RS485/RS422 conversion.
- RS485/RS422 Mode Selection: Some converters may have jumpers or software settings to select between RS485 (2-wire/4-wire) and RS422 modes. Consult the specific documentation for the converter if such options are present.
Huolto
The TRU Components TC-12358892 TC-KW-190 converter requires minimal maintenance.
- Pidä laite puhtaana ja pölyttömänä. Käytä puhdistamiseen pehmeää, kuivaa liinaa.
- Säilytä muunninta viileässä ja kuivassa paikassa, kun sitä ei käytetä.

Vianetsintä
If you encounter issues with the converter, consider the following:
- Laitetta ei tunnisteta:
- Ensure drivers are correctly installed. Reinstall them if necessary.
- Kokeile toista tietokoneesi USB-porttia.
- Tarkista USB-kaapeli vaurioiden varalta.
- Ei viestintää:
- Verify that the correct COM port is selected in your software.
- Double-check all serial communication parameters (baud rate, data bits, parity, stop bits, flow control) to ensure they match the connected device.
- Inspect the RS485/RS422 wiring for correct polarity and connections.
- Confirm the RS485/RS422 device is powered on and functioning correctly.
- Ajoittainen viestintä:
- Check for electromagnetic interference (EMI) from other devices.
- Ensure cable lengths are within specifications for RS485/RS422.
- Verify proper termination resistors are used on the RS485/RS422 bus if required by your setup.
