reading data from greenlee DM-210

[sezame]

I am quite experienced in LabVIEW DAQ programming (i gott PCI6024E DAQ and USB DAQ NI6009) but I have no experiance in serial comunication at all. All I want to do is to read measured data from Geenllee DMM DM-210.
I have already tried LabVIEW build-in examples such as Advanced Serial Write And Read.vi but it does not work...
As a return Vi gives 4096 data displayed in "hieroglyphic" form and error -1073807253. Where is it a problem..?...
I have no papers about DM-210...and have no idea about RS232 protocol used...Thank you for your convenience...

Right click on the error out indicator and select 'Explain Error'. This error indicates you have a mismatch in the com settings. You have to get a programming manual from the vendor that explains what the com settings are, the type of serial cable to use, and the commands/responses. The vendor does provide it's own software for communicating with it. You could try a serial port sniffer such as portmon.
