9. استكشاف الأخطاء وإصلاحها

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

• لا يوجد طاقة: Ensure the power adapter is correctly connected and providing the specified voltage (DC 5-36V). Check the POWER LED.
• لا يوجد اتصال بالشبكة: Verify the Ethernet cable connection. Check network settings (IP address, subnet mask, gateway). Ensure the Ethernet port LEDs are active.
• فشل الاتصال التسلسلي: Check serial port wiring (RS232 pinout, RS485 A+/B- polarity). Verify baudrate, data bits, parity, and stop bits settings match the connected serial device. Observe 232TX/RX and 485TX/RX LEDs for activity.
• لا يمكن الوصول Web الواجهة: Ensure your computer's IP address is in the same subnet as the converter's default IP (192.168.0.x). Try pinging the converter's IP address.
• اتصال متقطع: Check for network interference or cable issues. Review KeepAlive and time-out reboot settings.
• اعدادات المصنع: If configuration becomes problematic, perform a factory reset.
