AM 100 and CR 10X communication [RE-wrenches]

[John Raynes]

<x-flowed>

Greg,

If you can tell me more about the type of data that the AM100 puts out, I 
can probably help you.  Is the AM100 putting out straight analog signals or 
is it putting out a digital data stream in an RS-232 type format, or 
something different?

CR10X's can handle RS-232 type data within some strict limits, but it can 
take some tricky programming in the CR10X to parse the data stream.  In any 
event, the CR10X needs to be programmed so it knows which inputs to 
measure, and how to scale and store the data.

Contact me on or off-list if you want and I'll try to help you further,

Dear Wrenches,
I installed a small grid tie PV system w/ an AM100 monitor and GC 1000
inverter on a school here this summer. The contractor doing the data
acquisition and web stuff got busy with other projects and is just now
trying to finish this up. He's able to download data from all the
instrumentation, except for the AM 100. He's not been able to get it to
communicate with the CR10x datalogger.
I was wondering if anybody out there has a AM100 and a Campbell
Scientific datalogger talking to each other? We're wondering:
- what communications protocol do you use to get the AM100 and the CR
10X to talk to each other?
- do you need to use an RS232 interface device of some kind?
He just needs to get the most current data set to the CR 10. Any light
you can shed on this would be wonderful.
Thank a lot,
Greg
