Classic 250-CP
« on: June 04, 2019, 03:07:46 PM »
The Classic 250-CP is a Standard Classic that was a custom order.

They DO NOT have multiple MNGP slots so they can not be used in Follow me.
They DO NOT have AUX 1 or 2 terminals so they can't be used with a WBJR or any AUX functions.
THey do not have ARC Fault protection.
MNGP can not be programed for Voice.
None of these features can be added back to this board.


They DO HAVE an Ethernet Port so they can be used with MM2 and the Local App.
They can be updated normally using our normal Firmware via USB
They have Ground Fault Protection
BTS input jack is functioning

Most of them still are under warranty and will carry that warranty until they reach the 5 year mark.

Price on this item is $250.00 each. First come first served.

Please email sales@midnitesolar.com  to order.

Does it come with an MNGP?
How many MNGP slots does it have?

They have an MNGP, The MNGP has no speaker so thus no voice.

The Classic itself only has one jack instead of 3 for the display and follow me

Wind?

Yes, wind tracking too.   There may not be an aux output to smartly control a clipper though for high speed and high voltage limiting.

That could be done using modbus externally using a Rpi or some other small computer board to read the Aux states in clipper mode to control a clipper.

If you aren't using more than one Classic in Follow-Me, then the middle phone jack can run a second MNGP remote but the two bottom LEDs in the MNGP won't be controlled by the Classic because those two outside RJ-11 pins are not connected to anything in the Classic.  But that middle jack will power the MNGP and communicate with it.

The bottom jack is also active but does not have the 9 volts or so and is reversed pinout just like a regular Classic.

Bob, are you saying that you can add rj45s to a 250 CP for modbus?

No, unfortunately the RS-232 circuitry is not stuffed on these boards.

boB mentioned a middle and bottom jack, These classic cps do not have those. We do not recommend using these for wind as there is no way to control over speed using the aux out to a clipper

That's good to know. Is the jack that the mngp plugs into also rs232? If so, would it be possible to hook up RS 232 to rs485 converters on all classic CP's in a system and one mngp to monitor all of them? Would it be possible to use the sunny island converter and have 2 250cp classics tied to the master and slave ports on the converter and operate the same as if two classics were tied in normally, just without an mngp? (Assuming all wiring is done correctly, transmits tied to receives, voltage supplied where necessary.)


I bought two of these classic CP'S and a converter thinking that I didn't need the follow me Jacks. I didn't realize the converter uses the follow me jacks.

Given some programming skills yes you could read data from the top jack and do something with it. To the best of my knowledge there is nothing off the shelf that is plug and play.

Is the data in and out of the "remote" Jack different than the data coming in and out of the follow me Jack's?

No, it's the same, just a different port.  However, Follow-Me uses the middle and bottom ports.

You could accomplish the same thing with two or more Classics connected to the top remote port but would need a single board computer to aggregate the information.  For instance, the single board computer could periodically check each Classic and when one of them went to Float from Absorb, it could tell the other Classic to go to Float.  That's basically what F-Me does.   Then when one Classic goes to another mode like Bulk/Absorb, it will make the other Classic(s) do the same thing.  You just have to wait  for a wee bit for things to stabilize before cloning modes again.

Fairly simple and straightforward...   But somehow it's not always as easy as it sounds.  Still took us a while to get that working correctly.

Thank you Bob! Looks like I can connect 2 classics with a sunny island putting one to the master port of the converter and one to the slave port. Just have to change one cable and no mngps.
