The router packet appears to be sent independent of any other packet. Since this code reads the stream until each data packet is met by certain identifiers, knowing what belongs with what packet due to the limited Magnum documentation, is not certain. I'll move on to coding by timing packets. This subject doesn't seem popular anymore but, I can include the code if someone wants it.

Hi Watt_,

I have not messed with my solar stuff for a couple of years, but I see that you are making some inroads.

I would be interested to see your code.

Chris, I will upload the changed code. I hope Paul doesn't mind. I best add a note in the header.  I'll make a few changes to clean up my mess. I probably won't revisit this code unless you find a need.  Thanks for your time in this.

*****On second thought, I should have considered asking you if you would be interested in running version of the changed code to see if it will complete on your system and decode your hardware.  Would you be so inclined?   
Thanks again.

Chris, I will attach the code. If you get a readout of some sort with all zeros or the program stops, there is a reason for each. The zeros mean the data is being added to a buffer in the middle of a stream. Because the data checks are done via known data markers, there is no way to clear the buffer without a lot of effort or at least more than is needed at this point. Simply restart again until the program runs and either stops or reports data. If the program stops, that means it has copied 5 seconds of stream. Either way, you might copy the stream to a text file and post it so we can view the data or post all of it here if it will fit. It will time out after 5 seconds and exit. If you get data in the end, please post that data.  We can clean the code up later but for now, I'd like to try this. Thank you. Please find attached.

Here is a byte/time txt file of about 350 some odd bytes read from the RS485 connection. This is python so the times are a bit slower than what I see with C. Could be my poor coding skills causing the increased time from processing overhead but...  Here it is at any rate.

Thanks for the effort and keeping this thread alive.  I am hoping to start testing this out.  Will help give you some feedback.

Hello jamesmc,

Here are a few items I have that I've been working to test and decode:

MSH3012M
MS2012
MS4448PAE
RC
ARC
RTR
*ARTR* If it ever arrives....
BMK
ME-WEB-wired
AGS-N

I'm sure there are other devices laying around I've forgot about.  Getting as many devices decoded as possible will surely help clear up a lot of information in these packets. 

I've been working on (slowly) matching different items to different inverters to see what sort of data is sent on the data wires. I have not sent any commands as of yet to keep as many bytes unchanged.  A few minutes here and there is slow progress.
My immediate goal has been met. I'm polling ever few seconds to parse voltages and current to help sort out my Classics during charge using NewModBus from RossW. Eventually, though, I want to be able to limit the current into my batteries with the inverters are charging my batteries from and AC input source. 
A little live data. The cell balancing is a bit of trouble on these AGM cells....   http://ranges.albury.net.au/watt/index.html
And a few pics of the mess. https://www.anotherpower.com/board/index.php?PHPSESSID=qr21p23eaksht1auhe3fc7b3n6&topic=872.msg14752#new
And here is the Magnum data being sent to their server.  This is nice for comparison of data....    http://data.magnumenergy.com/mw5092
Any data you can provide would be nice. Thank you.

After playing around with this stuff, I'm thinking the A-RTR and the PT-100 charge controller may have a lot to be learned from as far as control. Guess I better get a Magnum charge controller coming and installed.

Has anybody written any software for the Magnum Inverter that uses the Ethernet Connection to a local Network?....Similar to the Classic Status Panel software?

I know this reply is late to the party, but....

I have developed  and published a complete Magnum Energy network compatible data reader that  works with a simple REST API / JSON interface. The "reader" can be extended to support other technologies. currently I have a MorningStar Charge Controller (Modbus) and a very experimental OutBack (SunSpec) interface. Alas, no Midnite solar support but contributions are welcome.

It''s available https://gitlab.com/Magnum_Energy/distribution here. It is designed to be modular so bits can be added and existing bits adapted to other uses.

Also included is a generalized data logging set of tools. It too is extensible and can log to any, or all of CSV, JSON files or directly to a MySQL database.

Thanks Charles for sharing your work.   These tools should be a great help to many,   here.   I am not quite there yet   ...

Thanks,   again,   Vic
