Has anyone else got this set up?
It's linked through a spare 'RAIN' port on one of the Transmitter boxes, in my case the one with the anemometer.
Just can't get it to see it atm and looking for some advice.
Many thanks

My Instromet sunshine recorder is linked up to an old Davis Wizard 3. I ran a wire from the two-pin 60 second pulsed output (whilst the sun is shining) of the control unit of the sunshine recorder to the input of the two-pin rain port of the Davis. It makes no odds regarding polarity. You can check that the pulse is working by using a mulitmeter. You set the Davis to record in inches so each pulse forwards the reading by 0.01, equal to 1 minute.

Thanks Nick. Atm I'm not seeing anything from it, I think the sun is recording, but can't check until I can connect the datlooger (located in different room now).
The setting to inches I'm confused with as the main rain gauge on the ISS is mm. Can this other connection on the seperate Davis transmitter unit (anemometer one), be set independently of the other?
I only got this on Friday as my old one I've had since 1999 was recording sun at dawn and dusk regularily, so needed replacing.
I have emailed Adrian at Instromet so hopefully will get some answers on Monday.

I made a mistake in that the pulse output from the Intromet control unit is in 1/100 of an hour (it is labelled on the circuit board and has a two-pins), therefore the pulse will be every 36 seconds. You then switch to inches instead of mm as this will then coincide with 0.01 of an inch equalling 36 seconds, therefore your reading will represent time for sun shining.
I've had my instromet recorder since 2006 but the glass domed sensor started to become corroded and misted up so I replaced that with their updated sensor about 3 years ago. The control unit is still the original so yours may be different.
Adrian is usually very good at sorting out these things.

I'm waiting for a 5m 9 way D to 9 way D cable to arrive from Amazon so I can connect the lgger back to my computer. I put the logger on my Laptop but I can't remember what my authentication number is so can't open the software up:-( Hopefully Adrian will sort out another code.

I have just finally got it to work, but not on the Wireless VP2. I still have my old WMII running and replaced the 'Rain' cable with the new 'R&D sun link cable'. I also don't have a problem with changing to 'inches', as the old raingauge will no longer be used. Just need to work out how the conversion works, or maybe it's just what it now displays as a decimal number (not hours).

Your R&D control unit is the more updated version but mine states the output is 1/100 hours, if the same on yours and the WMII is set to inches then the display will be in decimal hours.
You can easily determine if the output is in 1/100 hour pulses with a multimeter if and when the sun finally decides to shine again. You can then use Davis or other software to output your sunshine recorder date in real time to your website as I have done at http://www.ottervalleyweather.me.uk
I also upload data from my BL sunshine recorder to my website too.

As I also have the R&D datalogger connected hopefully they should read the same, I'll chack later as luckily we are getting a little sun here atm.
I am also having delivered the new R&D Display that goes with the new box.
Here is the data on the old Weatherlink page, you can see what being recorded as Rain in inches...

I've now got the new Sun Sensor display as well today. I'm struggling with the data from 3 different places.
1. Display 01:03:00
2. Data logger 01:09:00
3. Davis 0.80 inches
Must admit I had a problem when I first plugged the new display into the new box, where it gets it's power from,where it was recording sun continuously. I think/hope it was because I hadn't plugged it in far enough. However, the hours it was lit up wouldn't change. Btw, even with the old sun recorder/display, I always had the disparity with the logger.
Still very early results, so it may all become clear as the days pass.

I don't think I can offer a lot of help as your datalogger and control unit are different to mine. I'm still using an old Pico ADC-16 datalogger which I installed in 2006. I set it to use a threshold of 2.5 volts to record as 'sun shining', the output from the control box is 5V but I limited the voltage to the recommended 2.5V for the datalogger using a resistor. The datalogger records an average of the voltage across each minute. 2500 mV = 1 minute of sunshine; 1250 mV = 30 seconds. The data is stored as a CSV file and can be imported into Excel and the sunshine total calculated with a high degree of accuracy. It has been working faultlessly since I installed it all those years ago.

Thanks Nick. I ran the Pico ADC-16 many years ago, you just reminded me of this.
I just need some sunny days to make a better assessment. I have set my WMII logger to 15 minute intervals now, so a full hours sunshine (whenever we get it), should tell me more :-)
After I reconnected things yesterday it stopped the continuous recording error, it looks like I hadn't pushed the connector in far enough, but I won't be sure until I see it working as I'd expect it o.
Thansk again.

Strange one this Nick? Just back from a week away so hadn't had a chance before to look at this
Can't work out what my Web display is saying?
The inches it shows on the web is different to what's on the WMII, today for example:
2.74 on my website
3.48 on my WMII display, however this formula seems to work for ALL days within +-0.01with what I've so far kept a record of...
2.74 x 0.2682 + 2.74 = 3.4748
The new R&D display reads:
03:28:48 (hrs:mins:secs) which equates to 3.48 (Decimal).
It works, but I can't think why it's doing this. I'll email Adrian at InstroMet as it's probably something obvious but the penny hasn't dropped for me yet.
I posted incase something jumped out with you :-)
Regards

Sorted... The error was in the config file, I still had it set to mm, now inches.
