Page 2: Product Introduction
The ACC7310-M currently includes radars in both ACC7310-M2 and ACC7310- M3 models. ACC7310-M2 is used for 3-lane detection. ACC7310-M3 is used for 6- lane detection. ACC7310-M radar adopts the FMCW radar system. The distance and speed of the moving target are calculated by 2D-FFT. The radar can operate in continuous output mode and single-point trigger mode under different protocols. - Page 3 Figure 2 ⚫ Length：189.5mm ⚫ Width：98.0mm (Diameter of chassis) ⚫ Height：266.0mm The radar has two external cables. One of which has two core wires used to connect to the power supply. The red core wire is connected to the positive pole of the power supply, and the blue core wire is connected to the ground wire of the power supply.

Page 5: Mounting Guide
3、 Mounting Guide ACC7310-M usually is mounted on a crossbar, in the center of all lanes. For example, when using ACC7310-M2 to cover three lanes, it is necessary to mount it in the center of the second lane. As shown in Figure 3. - Page 6 installation heights. As shown in figure 5, the variable α is the pitch angle of radar. Radar Radial distance Hight Road Longitudinal distance Figure 5 Schematic diagram of radar adjusting pitch angle The pitch angle α is adjusted according to the mouting height of the radar ,as shown in table 1.
- Page 7 Figure 6 Schematic diagram of horizontal state adjustment Figure 7 the initial angle is 0° ② According to the actual mounting height, find the angle α given in table 1, and the final pitch angle is (γ＋α) on the side scale, with the tolerance of ±1°. For example , if the radar is mounted at 7 meters height, the initial pitch angle is 0°, and the radar pitch angle (α+γ) is 15°(Figure 8).

Page 10: System Debugging
XX-XX，WIFI Password：12345678）Open the ACC7310-M radar debugging host computer, select TCP / IP transparent transmission mode, the server IP is 192.168.1.1, the port number is 8899, click "connect to network", the radar debugging host computer should display "connected radar", as shown in Figure 11 . - Page 11 Figure 13 Installation height and deflection angle settings （3）Observe vehicle track In the track display interface on the left side of the debugging host computer, observe whether the track of the passing vehicle is upright (start tracking from 40 meters away, the tracking track is in the set lane), as shown in Figure 14. If the track is too short, the pitch angle of the radar is too large, and the radar needs to be raised upward.
- Page 12 “SetDistance”, and the text box appears that the writting is successful, as shown in Figure 16. Figure 16 Capture distance set The capture direction setting bar is shown in Figure 17. The drop-down list has three options: bidirectional, destination, and direction. The user selects the appropriate capture direction in the drop-down list, and then clicks the capture direction setting button to complete the setting of the capture direction.
