UPS recognition

Hello,

I bought a UPS from a local resseler. The name on the box is Guard 1500 I don' t know where it came from, it has software for linux on the box but it's for old kernels. I know that they used software made by the German firm Generex if this can help.

Does anyone know how can I recognize which driver to use in order to make upsmon work with it?

I'm using NUT but I can't find the correct driver. The drivers are aprox. 110 and I can't stand trying them one by one, is there any smarter way to do this? Maybe in some way probing the hardware?

Thank you.

If it connects to the host via USB, try cat /proc/bus/usb/devices or lsusb (as root). Either might provide some identifying info to help make a selection (e.g., if the brand was resold from another manufacturer).

I am not sure if it can connect via USB. I'll try that out though asap!

nope, not USB :-/

I think I'm a bit fucked up with this..

That's too bad. So how does it communicate with the host--serial port, Ethernet, ... smoke signals?

I assume it can report its condition to a computer or there's nothing NUT or anything else can do.

Does NUT offer anything like a generic or "dumb" driver? Most UPS status data is just nice-to-have; all you really need is a signal for "batteries exhausted, shut down now." An APC UPS would call this "dumb" signalling mode.

If you can somehow get NUT to respond to at least that, you're not at a total loss.

Hi.

If it is a 'Inform Guard 1500" you may try the powercom driver.
The smaller 'Guard 625 AP' run with this driver.

Try this ups.conf

Code: Select all

[myups]
       driver = powercom
         port = /dev/ttyS0
        type = KIN1500AP
        desc = "Guard"
        linevoltage = 220
        shutdownArguments={{1,0},y}

If your line voltage is 115 enter this instead of 220.

To make the testing easy start the driver like this.

Code: Select all

 /usr/local/ups/bin/powercom -DD -u root -a myups

It should spit out something like this.

debug level is '2'
Values of arguments:
manufacturer : 'PowerCom'
model name : 'Unknown'
serial number : 'Unknown'
line voltage : '220'
type : 'KP625AP'
number of bytes from UPS: '16'
method of flow control : 'dtr0rts1'
validation sequence: '{{5,0x80},{7,0},{8,0}}'
shutdown arguments: '{{1,0},y}'
frequency calculation coefficients: '{0.000210,0.000209}'
load percentage calculation coefficients: '{6.134300,-0.380800,4.311000,0.181100}'
battery percentage calculation coefficients: '{5.000000,0.326800,-825.000000,4.563900,-835.820007}'
voltage calculation coefficients: '{0.954500,0.000000}'
DTR => 0, RTS => 1
input.frequency: 49.10
output.frequency: 49.10
ups.load: 0.2
battery.charge: (null)
input.voltage: 232.4
output.voltage: 232.4
STATUS: OL

If this work you have to test the shutdown and maybe change the shutdownargument.
