[Nut-upsdev] Prefered Method for UPS?

Thu Jul 8 11:50:08 UTC 2010

Hello,

since I had delayed the programming of the UPS Device part,  now  it  is
time to continue...

My Device is "24 V DC modular ATX PSU" which replace  the  standard  ATX
Power Supply in PCs and use 15-43 V Input Voltage.  The  microcontroller
is a TI LM3S5T36 Cortex M3 and I get the "UPS" infos using up to 4 Maxim
DS1780 and some I²C current sensors.  The ATX  PSU  has  4 Module  Slots
which can be indivdualy equiped.  Also the ATX PSU can be equiped with a
4-Cell LiPoly-Block (14,4V/12Ah).

Also the "24 V DC modular ATX PSU" identify it self as USB serial device
using /dev/ttxyUSBxx

All infos from the DS1780 and current sensors are currently stored in  a
multi-dimensional Array.

So, currently I realy do not know HOW I schould send the infos to NUT.

Can you tell me what the prefered method is for NUT?

The MCU is gattering the infos like:

1)  own identification (Maxim DS28CZ04)
    0000 -> "12345678"               # serial number           \
    0001 -> "24V DC modular ATX      # real name of the modue  | I²C EEPROM
    0002 -> "electronica at tdnet"      # Vendor Real Name        | Maxim DS28CZ04
    0003 -> "1.0.0"                  # Version                 |
    0004 -> "2010-07-08"             # Manufacturing Date      /
    0010 -> "24,0"                   # Input voltage  (200mV/LSB)
    0011 -> "12,0"                   # input current  (0-25.5A)

2)  Expansion Module Slot 0
    0100 -> "12345678"          # serial number      \
    0101 -> "ATX 1"             # real name          | I²C EEPROM
    0102 -> "electronica at tdnet" # Vendor Real Name   | Maxim DS28CZ04
    0103 -> "1.0.0"             # Version            | on module
    0104 -> "2010-07-08"        # Manufacturing Date /
    0110 -> "3,30"        # +3.3V voltage
    0111 -> "15,0"        # +3.3V current           (17.3mV/LSB)
    0112 -> "5,00"        # +5V   voltage
    0113 -> "5,0"         # +5V   current           (26mV/LSB)
    0114 -> "12,0"        # +12V  voltage
    0115 -> "8,0"         # +12V  current           (62.5mV/LSB)
    0116 -> "5,00"        # +5V   standby voltage   (26mV/LSB)
    0117 -> "0,3"         # +5V   standby current
    0118 -> "-12,30"      # -12V  voltage           (96mV/LSB)
    0119 -> "53"          # Temp  in °C             (-40 to +125°C)
    011A -> ""            # Fan Speed 1
    011B -> ""            # Fan Speed 2
    011C -> "false"       # Chassis Intrusion

2)  Expansion Module Slot 2
    0200 -> "12345678"          # serial number      \
    0201 -> "SATA 16"           # real name          | I²C EEPROM
    0202 -> "electronica at tdnet" # Vendor Real Name   | Maxim DS28CZ04
    0204 -> "1.0.0"             # Version            | on module
    0205 -> "2010-07-08"        # Manufacturing Date /
    0210 -> "3,30"        # +3.3V voltage
    0211 -> "15,0"        # +3.3V current           (17.3mV/LSB)
    0212 -> "5,00"        # +5V   voltage
    0213 -> "5,0"         # +5V   current           (26mV/LSB)
    0214 -> "12,0"        # +12V  voltage
    0215 -> "8,0"         # +12V  current           (62.5mV/LSB)
    ...

4)  Expansion Module Slot 4
    0400 -> "12345678"          # serial number           \
    0401 -> "Backup"            # real name               | I²C EEPROM
    0402 -> "electronica at tdnet" # Vendor Real Name        | Maxim
    0403 -> "1.0.0"             # Version                 | DS28CZ04
    0404 -> "2010-07-08"        # Manufacturing Date      | on module
    0405 -> "4"                 # Number of cells         |
    0406 -> "120"               # Capacity in mAh/100     |
    0407 -> "2010-07-08"        # Cell Manufacturing Date /
    0410 -> "14,4"        # Batterie voltage
    0411 -> "15,0"        # Dis/Charging current    \
    0412 -> "3.7"         # Cell Voltage 1          |
    0413 -> "3.7"         # Cell Voltage 2          | using
    0414 -> "3.7"         # Cell Voltage 3          | Maxim MAX11068
    0415 -> "3.7"         # Cell Voltage 4          |
    0416 -> "48"          # Temperature             |
    0416 -> "100"         # Charging state          /

Note:  I have currently 8 differnt Modules available and
       it is not limited to.

So, which is the prefered solution to send this data to NUT?

And my last question:

Is it possibel to SET values from NUT in the "24 V DC modular ATX PSU"?
I mean something like Alarm, Tresholds and such?

Thanks, Greetings and nice Day/Evening
