Then back to a no resistor no capacitor and had multiple on/off's but no additional tip when Cumulus starts so it was the capacitor. Anyway back to the capacitor which cured the multiples and I'll just live with the extra tip on the few occasions I restart Cumulus.

I've put an 'ignore first tip' setting in the next build; I was waiting to release it until we had more information. But if you think that with a capacitor and with the first tip ignored it's giving correct results (correct as in correctly recording one tip each time the device says there's a tip) then I'll go ahead and make it available. I've also added a setting to use RTS/CTS, so it would be useful if that can be tried also.

Hi Steve
As sods law would have it we've only had very light drizzle since I tried various tests but I have had a couple of correct on/off pairs.
So yes, as far as I am concerned, the option would be useful and of course others don't have to use it.
Thanks
Alan

Alan, is that still a 10uF electrolytic capacitor you are using?

ok thats my rg11 connected to a direct rs232 port using the dsr with no capacitors or resistors.

on start up of cumulus i can confirm that the dsr remains off.

just have to wait for some rain to check what happens and how it compairs to the tip bucket gauges.

is that instead of the dst/dsr?

Instead of, or as well as (with two RG-11s), on one or two COM ports. Any combination, but a maximum of two RG-11s, obviously.

Steve as the old laptop im using for this test only has one usb port its means having to disconnect and close cumulus to get the debug log onto a flash drive.

this is the log after about 30 minutes for you to look at and see if things are ok so far

debug.log

looking like rain shortly so should have more data by tomorrow

Hi Duke
Yes 10uF
I know those more expert than I suggest it shouldn't work but for some reason it does. It's agreeing with the Cumulus station bucket at 3.7mm and 3.6 mm so far since 0900 but it could be that both are under reporting as the manual gauge is a lot higher (6mm the last time I looked). It's the sort of light rain that tends to stick to the bucket funnel and it COULD be the capacitor is missing 'tips' altogether. It will be difficult to see if that is the case but the rain rate should give a clue when I get to analysing that.

Alan

Thank you Alan.

Now that Steve has given us the opportunity to save a USB port by having both on one serial port, how does that effect the connection of the cap as it would now be connected across the two pairs (pins 6 & 7) used by the RG11's or would you recommend keeping one on each port?

EDIT: did you mean across pins 6 & 7 and not 5 & 6?

question for Steve

as i only have one usb port i hunted out an old laptop cooler with 4 usb ports. closed down cumulus connected the cooler it installed the generic hub connected the wh1080 unit installed as hid device. thought ok everythings ok. opened cumulus and nothing error unable to find station. restarted laptop just incase just the same.closed everything down again and connected the wh1080 back where it was and rebooted and started cumulus worked fine.

tried this a few times same results. could it just be the old dell c400 note book cant handle it or an i missing something else.

by the way still no rain clear bloody skies. why does it never do what you want. oh well see what happens over night or tomorrow maybe the next day.

As long as it's running XP or later it should work. But if Windows can't find the station when Cumulus asks for it, there must be some kind of problem somewhere. I'm afraid I don't know what to suggest.

tried connecting the hub and pluging in a flash drive just the same so dont think its cumulus more the c400 has problems with the hub after all it is quite old. just have to go back to the old method of close culmulus and then copy the debug file to the flash drive and use the other laptop to send it. was just a thought. not thinking there was problem with cumulus.

Hi Duke
The capacitor is across the relay line (DTR/DSR) DTR +ve

Sorry Alan, I was confusing the capacitor connection with the resistor connection

.

Out of interest, if you were using RTS 7/CTS 8, which leg would be the +ve?

Hi Duke
RTS +ve
