Logging burn-cycle durations

Hang up your Chisels and Plane blades and take a load off with a recently turned goblet of your favourite poison, in the lounge of our Gentlemen's (and ladies) Club.

I've just dug out an XP Professional SP3 disk Rich.

Is that any good to you? PM me your address and I'll post it to you.

Cheers

Bob

Yes, I do.
I thought that would have been evident form the email I sent you yesterday with all the drivers you will need.
let me know if you did not get it?

Bob


Hi Bob...no email received this end, I'm afraid.

Driver for the RS232 seems to be resolved now.

I'm after a link to the DMM software. The CD that came with the DVM installs OK but when I hit Begin, get an error message saying 'File is corrupt'. Doesn't say which file ! Tried re-installing but no cigar.

EDIT: Have confirmed in Device Manager that the COM port assigned for the RS232>USB adapter is the same as that in the DMM s/w, baud rate same etc

Making some progress. Have uninstalled DMM and re-installed it. The File corrupt message has now gone and there now appears to be some communication between the meter and the software.

BUT...the DMM display shows values that are all over the place and the RS232 indicator keeps going on and off. Running at 2400 baud which should be OK? Notice that the Device manger properties has the option for Flow control....not apparent in the DMM software config options. So possibly this is the problem ?

If so would you recommend increasing or decreasing the baud rate ?

I'll dig mine out later and look at the settings but have other stuff I have to do first.

Thanks Bob.

Those settings don't give any communication between the two (yes, I did alter the COM port !). Neither does 4800 baud. 2400baud is closest to giving some sort of connection but flaky in the extreme. Dropping down to 1200 it starts to get worse. So all the hallmarks of a dodgy communication between the two.

I've got another RS232-USB adapter on order as I gather they are very variable in quality/working. If that fails then I have run out of ideas.

Ok it seems to ignore the port setting on the com port set up. Instead the settings adopted are taken form the dvm software set up under setup/ com port
Only 2400 works for me

Thanks Bob. I suspect the RS232-USB adapter now. Will wait for one from a different supplier.

You could try opening up the meter and inside there is the crudest of opto couplers, two LEDs pointing at each other. they might just be out of line???

Worth a punt.

Now that's what I call an opto-isolator ! All seems OK.

ok then there is only a possible dodgy serial interface left. Might be worth opening up to look for a dry joint or whisker of wire or just wait for the replacement.
