[Solved] Read timeout and unmatched response

Post by ClaudeF » 26.08.2015, 12:52

Hi all !

We are using Rocrail with HSI-88 interface, and it works fine with at least 3 layouts. But with another one, we have problems, quickly after power ON, we see periodically these traces :
20150826.154408.903 r9999c hsi88fb OHSI88 0752 reading unmatched response 2...
20150826.154408.966 r9999c hsi88fb OHSI88 0758 Unmatched response 0=0xFFFFFFFF
20150826.154410.008 r9999E hsi88fb OSerial 0685 ***READ TIMEOUT*** size=1 rc=0 read=0 errno=0 tries=100
20150826.154410.008 r9999c hsi88fb OHSI88 0758 Unmatched response 1=0xFFFFFFFF
And of course we lost the information from S88, all sensors are down.

So what does mean exactly these messages ? What are the potential reasons of losing communication between HSI-88 and Rocrail ? (of course we are using HSI-88 with RS232)

Thanks !

Hi Claude,

Please attach your plan, ini and trc files.

Here is the .ini file and the plan file.
rocrail.ini
DI1.xml
Do you really need the trace file ? 'cause we try a lot of things on this layout (connect / disconnect S88 wire, power ON / OFF boosters, etc...) it should have flooded the trace file...
You do not have the required permissions to view the files attached to this post.

Hi Claude,

check the communication cable if its nearby transformers or other electromagnetic distortion.
We are a team of crazy people which want to create a very big layout with many train, in Lyon (France).
S88 is not a good choice for big layouts.
CBUS, Rocnet and LocoNet are better choices for big layouts.

Ok I'll check the communication cable.
S88 is not a good choice for big layouts.
I disagree with that, do you know that Miniatur Wunderland is still using S88 ? And in some case without shielded wires (S88 and not S88N). The fact is S88N is an old technology but it's inexpensive and easy to use. In a business context that's 2 important points !

We find the problem ! We are running 2 Rocrail on the same computer and we didn't checked the option Disable checking for serial devices at startup (in the Controller dialog box).

Now everything works fine.
