Router setup

  1. Need a wireless router with usb host and openwrt.
    1. Hardware: [TP-Link TL-WR1043ND] https://www.epointsystem.org/trac/vending_machine/attachment/wiki/WR1043ND/wr1043nd.jpg?format=raw
  2. Upgrade it to openwrt
    1. Openwrt installation: https://www.epointsystem.org/trac/vending_machine/wiki/HotSpotInstallation#InstructionsforTP-LinkTL-WR1043ND
  3. open a browser and try open the admin page.
  4. install packages: go System/software menu (of course the router needs internet connection to acomplish this step)
    1. kmod-usb-serial-pl2303 (if you have another vendor like FTDI try to find appropriate driver for it)
    2. kmod-usb2
    3. ser2net
  5. ssh to to the router and try to plug the usb-rs232 cable
  6. after dmesg should see something like this: "
    1. usb 1-1: new full speed USB device using ar71xx-ehci and address 3
    2. usb 1-1: configuration #1 chosen from 1 choice
    3. pl2303 1-1:1.0: pl2303 converter detected
    4. usb 1-1: pl2303 converter now attached to ttyUSB0"
  7. open: /etc/ser2net.conf add the following line to end of the file
    1. 5678:raw:0:/dev/ttyUSB0:19200
  8. start ser2net: ser2net

VemsTune setup

  1. Preferences/ECU Communication
    1. select tcp: and write the correct IP:PORT in my case 192.168.1.3:5678
press detect

Enjoy your wireless V3.
