6. Uputstvo za upotrebu
Once connected and powered, the converter will begin operation. Monitor the LED indicators for status:
- PWR (Power Indicator): This LED turns red when the USB is connected and voltage is detected, indicating the device is powered on.
- TXD (Send Indicator): This LED turns green when data is being sent from the RS232 interface.
- RXD (Receiving Indicator): This LED turns blue when data is being received by the RS232 interface.

7. Održavanje
- Keep the converter in a clean, dry environment.
- Avoid exposing the device to extreme temperatures or humidity outside the specified operating range.
- Ne pokušavajte otvoriti casing or modify the internal components, as this will void the warranty and may damage the device.
- Vanjski dio čistite mekom, suhom krpom. Ne koristite tekuća sredstva za čišćenje.
8. Otkrivanje problema
- Nema napajanja (LED dioda za napajanje isključena):
- Check if the USB cable is securely connected to both the converter and the host device.
- Verify that the host device's USB port is functional.
- Ensure the power adapter is correctly connected and providing power within the 5-36V range.
- No Data Transmission (TXD/RXD LEDs off during communication):
- Confirm that the RS232 devices are properly connected to the converter's DB9 ports.
- Verify that the RS232 devices are powered on and configured correctly.
- Check your software settings on the host computer to ensure the correct COM port is selected and communication parameters (baud rate, data bits, parity, stop bits) match those of the RS232 device.
- Ensure the drivers for the FT4232HL chip are correctly installed.
- Intermitentna veza:
- Provjerite sve kablovske spojeve na labavost.
- Ensure the USB and RS232 cable lengths do not exceed the recommended distances (5m for USB, 15m for RS232).
- Minimizirajte elektromagnetske smetnje od drugih elektronskih uređaja.
