Pin Definition
9-Pin D-Sub Interface Pin Assignment
| Pin | Function |
|---|---|
| 4 | LIN Bus |
| 5 | GND |
| 6 | GND |
| 9 | Auxiliary Power 6-28V |
Device Connection
After connecting USB-LIN to PC, LIN connection requires power in addition to LIN line.
Connection Instructions
- LIN Bus: Connect to pin 4
- Ground: Common ground for pins 5 and 6
- Auxiliary Power: Pin 9 connects to 6-28V auxiliary power
Precautions
- Generally 12V power supply is sufficient, recommended not to exceed 18V
- If USB-LIN and the LIN nodes connected use different power supplies, common ground is required for proper communication
Status Indicator
After installing driver and connecting USB-LIN device to computer, device LED indicator status is as follows:
| LED Status | Status Meaning |
|---|---|
| Green light constant on | Device connected to system driver |
| Green light slow flashing | LIN interface initialized with valid baud rate; software connected to LIN interface |
| Green light fast flashing | Data transmission on LIN bus |
