My apologies for what might be a long message.
First, I have a working (many off ebay aren't) RM Young 26700 translator. It came with a Voltage In board, To that is attached a Young non-tipping (capacitative) rain gauge. A little reading in the manual for this thing and I've keyed in some instructions that get the rain gauge to function OK (sort of neat, actually, at least to play with).
It reminds me of entering a program on the old PDP-8 instruction by instruction keys, worse than programming in Assembler!
Anyway, having looked through the junk box of stuff I've accumulated over the years but not put to use yet, I came across another RM Young sensor, the 41342 VF temperature probe. There is a little factory printed sticker on the inside case with that number on, but a little curious that it says "Temp Out: -50F to +150 F = 0 - 5 V DC", since the spec sheet on line for that device number gives a drawing of the electronics board which is identical, and as is the 5 terminal green hook up with the correct wire labeling and matches even the colors recommended by Young, BUT the spec sheet says this is a "0-1.000v" output board.
If you look at the instruction booklet, there are numerous hookup diagrams for the many sensors this thing supports.
There IS a temp sensor that has differential inputs, and is seemingly meant to hook up to their temp input board, the 26726. The temp sensors that the manual says can connect are 41342, no VF or VC on the end. These have a different wire hook up to that temperature input board.
To look at the programming, one sees the INP TEMP instruction referencing the 26726 board, and settings to the instruction allow you to specify C or F, and offsets.
Obviously the 41342VF sensor, being a voltage output, wasn't meant to attach to that input board.
Not to fear, I have additional ports on the Voltage Input board. So I hooked it up, and when I got to the instruction for the Voltage input board there is not all the setup stuff I'd need to make it report temperature to the translator, but it does read the voltage off the sensor and show that as a raw number.
The curious thing is that the instruction for the Input Precip specifies that it will read the Voltage Input board, but the instruction choices indicate that it 'knows' that the voltage is from the self siphoning rain gauge, and must use some sort of look up table to change the raw voltage to mm or inches of rain, etc.
There is no similar Input Temperature instruction that I can find that allows me to do this kind of choice for the voltage input when a temp sensor they supply is used.
I've looked to see if there is a way to hook a voltage output sensor up to the TEMP board, but can't find anything in their printout.
Also, if the spec sheet says this is a 0-1.000v output, why does the little sticker inside the sensor package on the electronics board say 0-5.000 volts out?
Has anyone ever interfaced one of these units, and specifically know how the temp sensor (according to specs is very accurate) with voltage output can be mated easily?
Just hoping, this is sort of a fun unit to play around with. I have a wind module too that I think will work and will get a spare 05103 out to fiddle with if I get this working.
