I need Fluke 187 & 189 DMM RS-232 commands

X-No-Archive: Yes

Hello,

could someone provide or help me locate additional command set for the
Fluke 180 series DMM? These multimeters are dual display and are
capable of exporting the value of both displays as well as the minimum,
maximum and average value at every interval when you use the Fluke
provided software.

There is a documentation here
http://cfa-www.harvard.edu/~thunter/manuals/RemoteSpec89_18X.htm but it
only provides the "QM" command that displays what's on the primary
display.

If there is no resource, how difficult would it be to intercept the
RS-232 communication between the meter and the computer and sniff the
commands?

Could you connect the Tx output of COMx to the Rx input of COMy and
then use a comms app such as HyperTerminal to capture the data to a
text file?

Could you view the contents of Fluke's .exe files with a hex editor?
Look for text strings in the vicinity of known commands such as QM.

For example, in Win98SE you can view a file, in a DOS box, as follows:

edit /r /64 filename

The "/r" indicates read-only mode.

When you find new commands, use HyperTerminal to send them to the
meter.

If the files aren't too large, you are welcome to email them to me.

Use a real serial port sniffing application (which requires another PC
with 2 serial ports). You want to capture the command and reply
side-by-side or it'll be a PITA to decipher the protocol.

Capture the command using the single-port technique that I have
described. Then issue this same command manually by connecting to the
DMM using HyperTerminal. You will then see both the command and the
reply on your screen.

I have used a similar technique to decipher the proprietary protocol
for a Casio digital diary.

If this is under windows, PortMon from Sysinternals is your friend.
The site appears to be down right now; I guess they got slashdotted.

My Fluke PM97 Scopemeter uses the CPL Protocol. These commands appear
to be the same as those used by the Fluke 180 series DMMs.

For example ...

QM = query for measurement data
QW = query waveform
QS = query setup
RI = reset instrument
ID = identification query

Contact me via email for more info.

Hi Franc,

I located the DLL file which I think contains instrument profile in the
FlukeView Forms directory, which is less than 1MB. I sent it to your
email, but it came back undeliberable. Please email me from the email
address which you can accept the file. I will send again.

Thanks for your help.

You need to de-spam my email address as per my sig line.

FWIW, the V4.08 firmware .bin file for a 190 series Scopemeter
contains the following text (there may be some errors):

AS AT CI CL CM CV DS EM EO EX FM GD GL GR ID IS PC PS QC QI QM QP QS
QW RB RC RD RI RS RT RW SO SS ST TA VE WB WC WD WT WW RN HO ZCD (?) DT
RP IM MD

These look like Query commands: QC QI QM QP QS QW

See http://assets.fluke.com/download/scopemeter/FlashTool_V408.exe

I'd try PortMon as suggested elsewhere in this thread. IMO it looks
like your best approach.

Otherwise you could try this:

edit /r /64 filespec

The above command (executed in a Windows DOS box) will display a file
in read-only mode. You can then search for text strings such as QM.

I'm using Win98SE so I can't say whether this approach works in Win
XP. You might need a different hex editor, eg HexEdit.
