Summary of change:
'''VemsTune Connection via TCP''' * possibly '''wireless''' ! * or ... ECU is '''over the ocean''', ECU is over the sea... VemsTune can connect to VEMS v3 ECU (or to [http://shop.vems.hu/catalog/engine-management-c-1.html VEMS Round gauge]) via TCP. '''LAN Requirements''' - local network * a PC/notebook or a smart wifi router device is required on the ECU side ** the IP address of the device must be known (ifconfig on unix, ipconfig /all on windows). IP can be any (including 10.x.x.x or 192.168.x.x ) * VemsTune (of course) See WAN requirements below if the ECU is distant instead of the local network. http://www.vems.hu/files/pacsa/tplink-v3/tplink-v3.jpg '''Router setup''' # Need a wireless router with usb host and openwrt. ## Hardware: [https://www.epointsystem.org/trac/vending_machine/wiki/WR1043ND TP-Link TL-WR1043ND] https://www.epointsystem.org/trac/vending_machine/attachment/wiki/WR1043ND/wr1043nd.jpg?format=raw # Upgrade it to openwrt ## Openwrt installation: https://www.epointsystem.org/trac/vending_machine/wiki/HotSpotInstallation#InstructionsforTP-LinkTL-WR1043ND # open a browser and try open the admin page. # install packages: go System/software menu (of course the router needs internet connection to acomplish this step) ## kmod-usb-serial-pl2303 (if you have another vendor like FTDI try to find appropriate driver for it) ## kmod-usb2 ## ser2net #ssh to to the router and try to plug the usb-rs232 cable #after dmesg should see something like this: " ## usb 1-1: new full speed USB device using ar71xx-ehci and address 3 ## usb 1-1: configuration #1 chosen from 1 choice ## pl2303 1-1:1.0: pl2303 converter detected ## usb 1-1: pl2303 converter now attached to ttyUSB0" # To make ser2net listen on TCP port 9000, '''append 1 line to the end of the /etc/ser2net.conf file:''' ## 9000:raw:0:/dev/ttyUSB0:19200 ## alternatively (using different, 50 msec timeout instead of 0, and a bit more options): ## 9000:raw:50:/dev/ttyUSB0:19200 8DATABITS NONE # start ser2net: ser2net '''VemsTune setup''' #Preferences/ECU Communication ## select tcp: and write the correct IP:PORT in my case 192.168.1.3:9000 press detect Enjoy your wireless V3. ---- I have tested this method with an Asus WL-500pP v2 router OpenWrt backfire 10.3 version, and with Pl-2303 usb serial converter succesfully. Installed packages: #kmod-usb-ohci #kmod-usb-serial-pl2303 #ser2net The vemstune works fine with tcp/ip connection but the communication is slower than native serial or usb-serial converter (19200baud). I have made some test: With wired connection the main overview group refresh about 17 Hz, and the calc model refresh more than 22 Hz. With wifi-connection tha main page below 10 Hz but calc model page sometimes go up to 22 Hz sometimes go to 3 Hz. ---- '''WAN Requirements''' - (ECU is at a remote internet location, possibly behind a firewall) * a PC/notebook or a smart wifi router device is required on the ECU side ** the IP address of the internet connection must be known ([http://www.ipgeotool.com/ ipgeotool] or from router admin inerface) ** the IP address of the device must be known if different (ifconfig on unix, ipconfig /all on windows) ** currently the chosen TCP port of this device MUST be directly reachable by VemsTune: ** if the device is behind a firewall, a DNAT rule in the firewall is necessary, similar to: ** iptables -t nat -I PREROUTING -i ppp0 -p tcp --dport 9000 -j DNAT --to-destination 192.168.1.3 ** In short VemsTune is like a web browser (special network setup not required) and the ECU side (ser2net) acts like a web server so special network setup is needed there (note: using raw, not HTTP protocol). ** developers will work on a relay solution to go around this inconvenience * internet connection on VemsTune side ** nothing special here: VemsTune can be behind a firewall, since VemsTune will initiate the outbond TCP connection like a web browser ---- '''setting up the ECU side PC or notebook''' To connect the VEMS ECU to the network A PC (notebook) is also suitable instead of the smart router. * ser2net on linux/unix with the following line in /etc/ser2net.conf ** 3002:raw:0:/dev/ttyUSB0:19200 8DATABITS NONE 1STOPBIT * TODO: ser2net on windows ** this will be bundled with VemsTune some day, with help and .bat files * TODO: net2com on windows (search "putty serial.backend") * TODO: other options for windows users
Optional: Add document to category:
Wiki formatting: * is Bullet list ** Bullet list subentry ... '''Bold''', ---- is horizontal ruler, <code> preformatted text... </code> See wiki editing HELP for tables and other formatting tips and tricks.
