The CANService is a small application which acts like a bridge between UDP/TCP and CAN.
It provides the same UDP ports as the Märklin CS2/CS3, 15730/15731, and TCP default port 15731 for communicating with a PC.
ASCII:
The TCP port 5550 is for use with RCAN. The linefeed option is required.
Binary:
The TCP port 15731 can be used in combination with the binary option.
2.1.656+
The TCP port 15731 can also be for used for BiDiB, if the command line option -usb
is set.
The default USB device is /dev/ttyUSB0
.
Rocrail must be set to BiDiB type TCP with port 15731. The hostname is the IP or name of the RPi.
An unused Raspberry Pi 1, 2 or 3 can be used as USB-TCP bridge.
Command line options:
The TCP/IP can only handle one client.
If there is need for multiple connections, this can be extended.
The CANService application is installed in the /opt/rocrail directory, and is included in all provided rocrail*.deb packages.
See: Raspberry Pi Setup
Set the CAN bit rate according to the target CAN:
CAN | Bit rate |
---|---|
RCAN | 125000 |
MBUS (CS2, CS3, GleisBox) | 250000 |
There are no settings to configure, just run it in user context.
To run it automatically after every boot, it can be setup like the Rocrail Server.
#/bin/bash cd /home/pi /opt/rocrail/canservice.sh <options>
Make the script executable:
chmod +x /home/pi/canservice.sh
Add it to the crontab with the command crontab -e
:
@reboot /home/pi/canservice.sh
