Communication Protocol Description

• UART Protocol
  • Active Output: Follows the NLink_TOFSense_Frame0 protocol. The module actively outputs data at 50Hz.
  • Query Output: Query frame follows the NLink_TOFSense_Read_Frame0 protocol; output frame follows the NLink_TOFSense_Frame0 protocol.
• IIC Protocol
  • Follows the NLink_TOFSense_IIC_Frame0 protocol. The controller sends read/write frames to the module with a specified slave address.
• I/O Protocol
  • Single Threshold: Threshold = Band Start. RX/TX output complementary levels based on ranging value relative to the threshold.
  • Double Threshold: Hysteresis comparison. Levels reverse when ranging value crosses high/low thresholds (Band Start and Band Start + Band Width).

I/O Output Mode Configuration

Single Threshold

• Interface type: IO
• Band Start: 1000 (mm)
• Band Width: 0
• Behavior: When ranging value < 1m, RX = HIGH, TX = LOW; when ranging value > 1m, RX = LOW, TX = HIGH.

Double Threshold

• Interface type: IO
• Band Start: 1000 (mm)
• Band Width: 500 (mm)
• Behavior: Levels reverse when ranging value crosses 1m (low threshold) or 1.5m (high threshold).
