How to integrate the HPC168 bus passenger counter with your system?
2026-07-02
Our HPC168 bus passenger counter supports two communication protocols for integration.
1. When the bus has on-board network access, you can connect via RJ45 interface using HTTP protocol (TCP connection).
2. If no network is available, the passenger counter device needs to connect a GPRS module via RS485 interface using RS485 protocol. The RS485 protocol requires the server to actively query, and the queried data is the total number. When reading, the current time is directly recorded. For example, at 10:00, a read shows 10 people entering and 10 people exiting; at 10:05, a read shows 15 people entering and 15 people exiting. This is the data for those 5 minutes: 5 people entering and 5 people exiting. The maximum total number that the device can store in RS485 mode is 999,999. Please refer to the details of our two protocols for further information.

What operations need to be completed after powering on the HPC168 bus passenger counting system?
After power supply connection, just connect the HPC168 passener counter device to a PC and log into the device's web backend for configuration. We recommend mounting the HPC168 bus passener counter at 2.1 meters height for testing.
HPC168 bus passenger counter supports DC 12V to 24V input. Turn off your PC's Wi-Fi and set its wired IP to the 192.168.1.xxx subnet. Connect the passenger counter device to your PC via an Ethernet cable, then open the backend at http://192.168.1.253:8191 on a browser to set the parameters.
If using a router, ensure it uses the 192.168.1.x subnet; reconfigure its network segment if not. You may also skip the router and connect the passenger counter directly to your PC with a matching static IP.
