    Getting started with uCAN CAN Ethernet converter video here, english version.

    Quick Start

    1. Connect CEC device with ethernet cable to your network,
    2. On your rooter check what ip address was assign to CEC device,
      or to avoid IP usage, install avahi - zeroconf client (bonjour for windows). Domain name is ucan.local ,
    3. SSH login: root, password: ucan,
    4. On Your web browser go to ucan.local address, ucan web application should display,

    Device has socketcand program running on ethernet port. Socketcand is a daemon that provides access to CAN interfaces on a machine via a network interface. The communication protocol uses a TCP/IP connection and a specific protocol to transfer CAN frames and control commands. To establish connection use socket client(ex. PuTTy) on configured port.

    PuTTy configuration page, remember to set valid port and contention type. After connection you should received <Hi> message. List off all available commands on socketcand project page .

    If You connect USB memory stick, device will log frames automatically on it. Frames will be saved in ASCI format. Frames are automatically packet to 100 MB archives, using logrotate utility. Logs can be also downloaded from internal website using UCANTools application.

    Tools

    CEC Linux distribution comes with many pre-installed applications see list below for details. Tools list:

  • uCANTools

    • uCANTools is web application working on port 8080, it has got features like CAN data handling, logs downloading and many more see uCANTools project for more info.

  • LogRotate

    • Logroate Linux program is used to handle with logs saved on USB stick. Logroate creates new log files and aggregates them. Log rotate is triggered by cron.hourly task.
