Xinje TH USB Device: Common for various Xinje interfaces; version 1.0.5.0 is a known stable version for certain legacy hardware. Open AutoShop → Communication Parameter → Select USB
USB-XC Cable: If you are using a conversion cable (USB-XC), it may require a separate Prolific or CH340 serial-to-USB driver if not automatically installed by Windows. 4. Safety and Connection Tips
Power Off: Always cut off external power before performing initial wiring or connecting expansion modules.
Cable Types: High-speed motion controllers (like the XDC series) or Ethernet-capable models (like the XD5) might use standard USB or Ethernet cables, but standard XC/XD models often require specific programming cables. XINJE PLC XD5 Series Programmable Controller User Manual
