Metex/Conrad ME-32

[Michael Bauer]

Hi,

I'm trying to use a Metex/Conrad ME-32 digital multimeter and LabView
and I didn't succeed yet.

By using the bytes at serial port vi after the serial port init. vi, I
recieve 0 byte.

Can anyone help me to solve this problem??

I'm using following parameters:
port: COM 1 (in LabView means port 0)
baud rate: 600
data bits: 7
stop bits: 2
flow control: input alt HW HShk (true)
sending as "start bit" a "D" and waiting 200 ms to read from com1



Thank you.

Michael

Personally, I prefer to use VISA but the older serial routines should work as well. First of all, have you communicated with the instrument with Hyperterminal (or equivalent) with these settings? You say you sent a "D" as a start bit. If this is a command to initiate a measurement, have you also sent a termination character? I've never used the ME-32 but all of the serial instruments I've used needing something like a CR/LF at the end of every line.

I had the same problem. For some reason I was unable to set the RTS and DTR line correct, so I simly attached two 9V Batteries instead of the lines( + to DTA, - to RTS, both reference to GND). It's not nice, but it works.

Timing needs about 500 ms waiting time.

Dear Victor and NI:

I have long difficulty to get data from ME-31for first trial of LabVIEW Japanese version more than week. It was the first time to get data from a serial device. So I doubt my skill, but it might be wrong.

It seems to me at last the answer was found.
I hope it works. Thanks Victor to make it.

By browsing this community, many person had similar problem to communicate METEX DMM.

I did not know many person had such diffuculty, so I did not access this community. But now I can down load the hopeful vi to enable me to do it.

Thanks NI also for providing this community.
I consulted with this problem to NIJ, but I could not get any suggestion on this community. So, I hope NIJ will regard this site as a powerful reply to customer's req
uest on technical support if possible. But most Japanese users and employees of NI in Japan seldom access English community because mother language is Japanese and not emphasized on using it.

If content of this community automatically was translated into Japanese, many Japanese users can read and use it more. In that case, translate quality will be not so critical with discramer. The content is very important. Is it worth considering to do?

Just for your information.
Best regards,
