Hi..
I am new with use of CR1000 datalogger. I am trying to connect this with PC using RS232 via loggernet.
I am failed to connect the datalogger with loggernet using RS232. I am using loggernet 4.0 version (bought 4 years ago for other use of CR5000). In fact in loggernet, CR1000 is not mentioned with other datalogger list. I have checked Baud rate in both datalogger and loggernet. I am using usb port in pc for connection.
I am using CS external display through CS I/O port.
Please help.
Thanks..
I suggest this blog article on troubleshooting serial connections.

dsclimate, In LoggerNet's setup you'll need a COM port then PakBus port then the CR1000 will show up as an available logger.

Thank you JDavis and Janet..
Hello,
I need your kind suggestion for measuring u,v,w wind from RM 81000 anemometer voltage outputs in CR1000.
I have changed the voltage o/p setting to output format one (i.e. u,v,w, sonic temp) using hyper terminal.
However, u,v,w reading are not giving correct values, but, sonic temp is giving correct value.
I am using the following main program in CRBasic for calculation of u,v,w,SonicT
-----------------------

Could you please help me further to measure correct u,v,w value from RM young 81000? I am using differential connection.
I would appreciate your kind concern as I stopped here in Qatar for this without any other help and response. I am really unable to get response from local Campbell Scientific partner in Qatar/UAE.
Please help.
