VisiCanEU WiFi Module ( with CanBus )

VisiCan Wi-Fi Module — CAN-Bus Edition Feature Version

In a large majority of vehicles, the ECU (Engine Control Unit) architecture permits only a single diagnostic client (Tester/Diagnostic Tool) to communicate via the OBD-II port at any given time. Consequently, attempting to run secondary devices such as P3 Gauges, LED/LCD performance steering wheels, or generic OBD gauges alongside an active VisiCan display results in communication conflicts.

The VisiCan CAN-Bus Gateway Wi-Fi Module features an integrated CAN Transceiver hardware circuit that actively snoops live telemetry queried by the VisiCan display and emulates standard OBD-II PID responses to secondary devices. This allows both display systems to operate seamlessly in parallel without ECU bus rejection.

⚡ CAN-Bus Interface & Operating Logic

• Communication Protocol & Rate: Operates at standard 500 kbps baud rate with 11-bit addressing. Responds to standard generic PID queries from secondary devices (P3 / Steering Wheel) using 0x7E8 / 0x7E0 diagnostic addresses.
• Streamed Data Scope: Secondary devices operate strictly in "Read-Only" mode. Only parameters actively displayed on the VisiCan screen and queried in real-time from the ECU are broadcasted. Secondary devices cannot execute Diagnostic Trouble Code (DTC) clearing or ECU write commands.
• Plug-and-Play Automation: No web interface configuration required; the module begins CAN broadcasting automatically upon bootup.

🛠️ D.I.Y. Wiring & Pinout Guide

Connecting the CAN-Bus Gateway Wi-Fi Module to the main VisiCan display is identical to the standard module. However, wiring connection to secondary devices (P3 Gauge / LED Steering Wheel, etc.) must be completed by the user as a D.I.Y. (Do-It-Yourself) installation.

📱 Core Wi-Fi Module Features & Capabilities

• 24/7 Automatic DataLog: Automatic internal flash logging of displayed live parameters (20-minute rolling log storage).
• LiveValues Web Dashboard: Real-time wireless telemetry streaming to mobile phones, tablets, or Android head units (250 ms / ~4 Hz).
• Wireless Management Interface: Full display configuration and system setting controls.
• Over-The-Air (OTA) Updates: Module firmware updates as well as main VisiCan gauge firmware and boot logo flashing.
• Custom Asset Flashing: Background bitmap and startup animation updates (5th Gen models only).
