9. ການແກ້ໄຂບັນຫາ

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

• ບໍ່ມີພະລັງງານ: ໃຫ້ແນ່ໃຈວ່າອະແດບເຕີໄຟຟ້າໄດ້ເຊື່ອມຕໍ່ຢ່າງຖືກຕ້ອງ ແລະ ໃຫ້ລະດັບສຽງທີ່ລະບຸໄວ້tage (DC 5-36V). Check the POWER LED.
• ບໍ່ມີການເຊື່ອມຕໍ່ເຄືອຂ່າຍ: Verify the Ethernet cable connection. Check network settings (IP address, subnet mask, gateway). Ensure the Ethernet port LEDs are active.
• Serial Communication Failure: 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.
• ບໍ່ສາມາດເຂົ້າເຖິງໄດ້ Web ການໂຕ້ຕອບ: 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.
