Hello,
Since I have now nearly all stuff running on my LH7A404 and now I am
working on my DS80C411, I like to know, whether NUT show the APC UPS
stats like the APC tools.
Currently I do not know, HOW NUT triber the USB-Poert to get out the
infos of the UPS. In theory I do send out only arround 5-60 lines of
data which then NUT or any other programs must parse or something
similar, but I have absolutly no clue about HOW NUT like to get the
infos,
Currently It looks something like:
----[ STDIN ]-----------------------------------
electronica at tdnet 24V DC modular ATX PSU
Slot 0: Base Module with PowerWhatch
SerNo: 00000001
Uin: 26.8V
Iin: 8.9A
T: 52,6?C
Slot 1: ATX 2 (144W)
SerNo: 00000001
+12V: 12.2V, 2.8A
+5V: 5.1V, 6.1A
+3.3V: 3.3V, 11.9A
+5Vsb: 5.0V, 0.1A
-12V: -12V, 0.0A
T: 58,1?C
Slot 4: SATA 4 (82W)
SerNo: 00000001
+12V: 12.1V, 0.3A
+5V: 5.0V, 0.7.A
+3.3V: 3.3V, 0.0.A
T: 48,7?C
Slot 5: Device 4 (68W)
SerNo: 00000001
+12V: 12.0V, 0.2.A
+5V: 5.0V, 0.3A
T: 49,2?C
------------------------------------------------
And this PSU is currently connected to a "VIA EPIA LN10000EAG"
with
1 GByte of memory, a 3w9550SXU-8LP, four SanDisk Extreme III 4 GByte on
SATA/CF-Adapters plus four Hitachi HTE521660J9SA00 with 60 GByte.
I should note, that "Slot 0" is always the "24V DC modular
ATX PSU"
itself and use a DS80C411 Microcontroller.
Slot 1 to slot 5 are the modules for ATX, PCI Express, P4, SATA or
Device.
Note 1: The DS80C411 check sequentiel the five slots over an I?C switch
and on each module I have a I?C serial EEPROM with the infos
like "Serialnumber", the "module name" and which
type of infos
are provided. The last one is required, since the A/D
Converters have an unique serialnumber from NXP and I have to
know, WHICH A/D Converter (each has 4 channels) is responsable
or each value.
After querying the 5 slots, the DS80C411 pull out the above
listing over the USB port continously each 5 seconds which is
for testing only to get things running.
The output of the USB port then can be easyly captured by ANY
programs which can read from the USB Port.
But this will bind resources, I likt to triger the output from
NUT...
How to do this?
And for the computer shutdown (UPS like), it is enough, if NUT
capture the value "Vin" of "Slot 2".
Note 2: The UVP (24V input) is only active for the PowerModules while
the DS80C411 consumes only some mA, it will be always powered
and has its own UVP which will be active, if the Uin is less
then 12V. This has the advantage, that I can write a small
NVRAM with for example 128 Byte which store all Power Up/Down
and its time and I can add something like the following at the
end of the USB output
----8<--------------------------
Power Up/Down Log:
1208275466: up
1208275478: down
1208275599: up
1208275972: down (UVP)
1208276173: up
1208276486: down (OVP)
1208276617: up
1208276815: down
1208279013: up
--------------------------------
What do you think about it?
Note 3: My current "24V DC modular ATX PSU" containing the
a) Base Module with PowerWhatch
b) ATX 2 (144W)
c) SATA 4 ( 82W)
d) DEVICE 4 ( 68W)
including the making of the four PCB's had cost me completly
980 Euros without my development time... The most expensive
thing is the enterprise for the manufacturing of the PCB's.
I think, building the WHOLE set with all PowerModules will cost
arround 2000 Euro. And then producing it in serie of 100 PSU's
with a config like
a) Base Module with PowerWhatch
b) ATX 3 (240W)
c) SATA 4 ( 82W)
d) DEVICE 4 ( 68W)
maybe arround 200 Euro.
But this is only for testing, since currently I do not know, whether I
should stay with the I?C stuff I a using currently (works perfectly but
is expensive, - arround 11 Euro more for the config above) or switch to
an I?C/1-Wire mix which could save money but require (heavy???) software
changes. And of course, the capacities of the DS80C411 are limited to
64 kByte.
Also I am looking for a smaller Microcontroller since I do not need CAN,
Ethernet or the Web-Server on it... :-)
Note 4: My current DS80C411 is an Evaluation Board provided by Dallas/
Maxim and is not put directly onto the ATX PCB (The ?C only cost
arround 22 Euro in a electronic shop while I have payed for the
Evaluation Kit from Dallas/Maxim 68 Euro I think).
