RS232 communication problem


MaximeD Apr 15, 2014 06:58 PM

Dear all,

I have a communication problem betwEen my PC and my CR1000.
I wanted to connect my sensor on the RS232 port and now it's impossible to connect with this port...
I connect a CR1000KD by CS I/0 and i can read my data.

Is it possible to reset my CR1000? maybe it's the only solution ?

Thank you for your help!

Cheers,
Maxime

Use the CR1000KD to stop the running program.

Your options to prevent the problem would be to connect the serial sensor to one of the control port pairs (i.e., C1/C2), or keep the serial sensor on the RS232 port and purchase an SC32B so you can connect from the PC to the datalogger over the CS I/O port.

Thank you for your quickly response!

I stopped my running program, but :
I update a programm, I have a warning : internal date storage memory was re-initialized.
CPU : templateexemple.CR1 -- Compiled in PipelineMode

And when i have no program, communication doesnt work...

My programm is like this :

'Main Program
BeginProg
SerialOpen (COMRS232,BaudRate,0,0,10000)
Scan (1000/Freq,mSec,0,0)
SerialIn (YChain,COMRS232,100,0,29)
U=Mid(YChain,2,6)
V=Mid(YChain,9,6)
W=Mid(YChain,16,6)
T=Mid(YChain,23,7)
CS7500 (Licor(),1,7,4)
'Call Output Tables
CallTable Young7500
NextScan
EndProg

Thank you in advance for your help.

What is your BaudRate in the SerialOpen instruction? My guess is that is does not match the Baud Rate used in LoggerNet's setup for communications with that CR1000. Change your LN Setup|COMPort|PakBusPort baud rate to match your CR1000's RS-232 baud rate and you should be good to go.
