Windows

I cannot find the rocrail.ini, plan.xml and/or trace files.

This is because Windows hides known file extensions by default.
Change this in the File Explorer:

  • Start Windows Explorer, you can do this by opening up any folder.
  • Click Organize.
  • Click Folder and search options.
  • Click the View tab.
  • Scroll down until you notice Hide extensions for known file types, un-check this line by clicking the check box.
  • Click OK


Rocview

  1. Rocview hangs at startup.
    • Remove the rocview.ini and restart Rocview. Some split panel values will keep Rocview from showing up. Or remove the split values from the rocview.ini file. (wxWidgets bug.)
  2. Rocview does no longer get update events from server and or freezes.
  3. Rocview cannot connect to the Rocrail server. (For example: “connection to localhost:8051 failed”)
    • The previous port 62842 must be replaced with 8051 in existing rocrail.ini and rocview.ini.
  4. Rocview 'hangs' after opening a Workspace.
    • The client TCP port is not set to 8051 in the rocrail.ini found in the selected Workspace.
  5. Rocview needs too much CPU power and has a bad performance.
    Check following options:
  6. Rocview is no longer visible at startup or it shows itself as a small line.
    • Shutdown Rocview (Task manager), delete the rocview.ini and restart Rocview.


Rocrail

  1. Rocrail crash at startup under Windows.
  2. “Interface ID is not set”
    • A none existing IID used or no default Command Station set.
  3. Rocrail needs too much CPU power.


Märklin CentralStation 2

  1. S88 Feedbacks do not report:
  2. I have problems to setup the CS2 network:


USB

  1. Connection lost after a random time: (transact OSerial 0625 read size=2 rc=-1 read=0 errno=6)
    • Keep transformers far away from the very sensitive USB communication cables! (http://forum.rocrail.net/viewtopic.php?p=21411)
    • Install available device driver updates.
    • Use short cables; A long cable (>3m) can cause problems if it is of poor quality.


Serial device user access (Linux)

To access a serial device the user must be added in the dialout group:

Command:

$ sudo adduser xxx dialout

Output:

[sudo] password for xxx: 
Adding user `xxx' to group `dialout' ...
Adding user xxx to group dialout
Done.

xxx = Your user name.
Re-login to activate the new settings.


Device or resource busy (Linux)

Note: This is a copy of the forum posting:

When connecting my OpenDCC Z1 to my new laptop (with fresh installed Kubuntu 12.10) I had to get my udev config to fixed:
1st I had to add an udev rules files as described on the OpenDCC webpage. I added a file /etc/udev/rules.d/99-opendcc.rules:

KERNEL=="ttyUSB*" ATTRS{idVendor}=="0403", ATTRS{idProduct}=="bfd8", SYMLINK+="opendcc/opendcc" 
KERNEL=="ttyUSB*" ATTRS{idVendor}=="0403", ATTRS{idProduct}=="bfd9", SYMLINK+="opendcc/schnueffel" 
KERNEL=="ttyUSB*" ATTRS{idVendor}=="0403", ATTRS{idProduct}=="bfda", SYMLINK+="opendcc/throttle" 
KERNEL=="ttyUSB*" ATTRS{idVendor}=="0403", ATTRS{idProduct}=="bfdb", SYMLINK+="opendcc/basestation" 
KERNEL=="ttyUSB*" ATTRS{idVendor}=="0403", ATTRS{idProduct}=="bfdc", SYMLINK+="opendcc/gbm"

But then the modem-manager always probed the new device. So I got always (in the rocrail terminal output or log):

20130115.170432.860 r9999I main     OSerial  0196 rocs_serial_open:open rc=16 read=0 write=0 [16] [Device or resource busy] 
20130115.170432.860 r9999E main     OP50x    1808 Could not init p50x port!

To stop modem-manager from to probe the OpenDCC Z1 I added this as /etc/udev/rules.d/70-mm-usb-device-blacklist-opendcc.rules:

ATTRS{idVendor}=="0403", ATTRS{idProduct}=="bfd8", ENV{ID_MM_DEVICE_IGNORE}="1" 
ATTRS{idVendor}=="0403", ATTRS{idProduct}=="bfd9", ENV{ID_MM_DEVICE_IGNORE}="1" 
ATTRS{idVendor}=="0403", ATTRS{idProduct}=="bfda", ENV{ID_MM_DEVICE_IGNORE}="1" 
ATTRS{idVendor}=="0403", ATTRS{idProduct}=="bfdb", ENV{ID_MM_DEVICE_IGNORE}="1" 
ATTRS{idVendor}=="0403", ATTRS{idProduct}=="bfdc", ENV{ID_MM_DEVICE_IGNORE}="1"
