Connecting Kern GAB30 via RS 232 to DasyLab

[sajad2006 · Accepted solution]

Hi,

HEX didnot help, but I figured it out anyway.

Seems that PC had a problem with the port, everytime it wanted to connect to the balance, i.e. sending request for data, somehow the port was missed from PC, although it Device Manager showed it is still working properly.

Anyway, I fixed this by opening the all ports, but still no data.

Finally, I found out that if I active the correct baudrate on the balance settings AS WELL AS activating AUTOPRINT PC there, it works, ALTHOUGH on the balance manual says only one of them should be activated and they cannot be ON at the same time!

Thanks ALL!

Thanks for the update.

I'm glad that you were able to work it out.

Hello,

Thank you very much for the reply. 

I am pretty much facing the same problem, I receive respond through command for  the weights. however I think there is a problem with RS232 configuration in Dasylab. would you please explain why did you use s\r\n ? is there any other combination?

[CJ_Butler__DASYLab_Pro]

When I reviewed the manual for the scale, as I said above, the command for a stable value was 

s<CR><LF>

To send that command in the Data Request command, you change it to 

s\r\n

It's easier to help and follow a conversation if you create a new topic. 

When requesting support for DASYLab

• DO NOT post your full DASYLab serial number
• Please tell us 
  
  • the version of your DASYLab software, 
  • the level of your software (Lite, Basic, Full, Pro)
  • the exact DAQ device by manufacturer and model,
  • your operating system and computer,
  • and, if appropriate, a copy of your worksheet.

Data request via RS232 monitor works (all the commands works) however when I use ''s\r\n'' or ''W'' I only get 0 and when I use the defines ''\r'' I have no reading.

1. I am connecting kern scale (Gab30) via rs232 (CFS-A01)
2. DasyLab 10 Basic
3. Windows 10 
4. worksheet is attached 

It would be great if you have a look,

Regards.

DASYLab 10 is not supported on Windows 10!

Is the device configured correctly to send data? Many devices need a setting turned on to respond to commands or to output data continually.

Thank you very much 

I have installed everything on windows 7 and also you are totally right the auto-print was disable and had to enable it from the scale itself please have a look at my rs232 monitor(attachment). Although I have auto print I still do not get the correct reading. I still get 0.

Do you have further advise?

[CJ_Butler__DASYLab_Pro]

Excellent progress. 

Now change the Data Format form a\r to 

a\r\n 2x

Tell me how that works. 

If it doesn't, then try

2x a\r\n

The first data point may be garbled, but the rest should be okay.

[sahandfarhang]

I appreciate your quick reply.

I tried both 2x a\r\n and a\r\n 2x still I get 0. Do you think it might be something to do with Baud number? as I have limited knowledge on this I am asking? I also tried Hex and ASCII but both gave the same results.

[CJ_Butler__DASYLab_Pro]

If the RS232 Monitor is showing clear numbers, then it's not the baud rate. 

Try this

a 2x \r\n

If it doesn't work, send me screen shots of both the ASCII and the HEX in the RS232 Monitor.

Also, attach the simple worksheet with just the one RS232 Input and a List module.
