Now I'm trying to get it working with USB (the UPS has both and it's
getting harder to find machines with serial ports) - if it works
with <b>blazer_ser</b>, should it also work with <b>blazer_usb</b>?<br>
<br>
When I plug the USB in, 'dmesg' shows this:<br>
<br>
<b></b>
<blockquote type="cite">[68527.748033] usb 4-1: new low speed USB

<br>
and <b>/dev/usb/hiddev0</b> appears.<br>
<br>
So I tried with this:<br>
<br>
[myups]<br>
driver = blazer_usb<br>
port = /dev/usb/hiddev0<br>
desc = "Local UPS"<br>
<br>
<b>/usr/lib/ups/driver/blazer_usb -a myups</b><br>

libusb couldn't open USB device /dev/bus/usb/002/001: Permission

libusb couldn't open USB device /dev/bus/usb/004/001: Permission
denied.<br>
libusb requires write access to USB device nodes.<br>
No supported UPS detected<br>
<br>
and <b>/dev/usb/hiddev0</b> disappears.<br>
<br>
I added the following to '/etc/udev/rules.d/52-nut-usbups.rules':<br>
<br>
# GE EP series<br>
ATTR{idVendor}=="14f0", ATTR{idProduct}=="00c9", MODE="664",
GROUP="daemon"<br>
<br>
I also edited the 'blazer_usb.c' file and added this:<br>
<br>
{ USB_DEVICE(0x14f0, 0x00c9), &krauler_subdriver },
/* GE EP series */<br>
<br>
(also tried other subdrivers - cypress, ippon, ...).<br>
<br>
I also manually change permissions on '/dev/bus/usb/*/*' to 666, but
it also didn't help.<br>
<br>
Anything else to try?<br>

The short story - it seems that GE EP series is (somewhat)
supported by the <b>blazer_ser</b> driver (haven't tried the USB
connection yet). I had to use the 'cablepower = none' option as GE
only uses TX and RX.<br>
<br>
<br>
The longer story - I 'sniffed' the RS232 communication between the
GE supplied Java software 'upspilot' and UPS. From that I found
out the baud rate (2400) and I learned about a couple of commands
(not knowing what they mean):<br>
<ul>
<li>CB24</li>
<li>WH</li>
<li>Q1</li>
<li>Q4</li>
<li>Q7<br>
</li>
<li>QS</li>
<li>...</li>
</ul>
Then I user 'minicom' to try these commands out and this is what I
got:<br>
<br>
Q1 -> (232.0 140.0 220.0 001 50.0 2.27 31.0 00000000<br>
Q4 -> (232.0 243.0 000.0 001 220.0 49.9 001 50.0 342 343 273.0
31.0 LM<br>
Q7 -> 07102218014 V_01<br>
<br>
OK, I'm getting somewhere - but I have to figure out what all of
this means. So decide to unpack some .jar files and have a look in
there. A friend helped by 'de-compiling' all .class files and
using 'grep' I searched for these commands.<br>
<br>
There is a file named 'UpsProt.class', which (de-compiled)
contains this:<br>
<br>
/* 25 */ Santak1Class.command[0] = "Q";<br>
/* 30 */ Santak1Class.command[1] = "Q1";<br>
/* 35 */ Santak1Class.command[2] = "Q4";<br>
/* 40 */ Santak1Class.command[3] = "QF";<br>
/* 45 */ Santak1Class.command[4] = "MD";<br>
/* 50 */ Santak1Class.command[5] = "QP";<br>
/* 55 */ Santak1Class.command[6] = "PSmGnLpHqExxxxDxxx";<br>
/* 60 */ Santak1Class.command[7] = "PF";<br>
/* 65 */ Santak1Class.command[8] = "T";<br>
/* 70 */ Santak1Class.command[9] = "TL";<br>
/* 75 */ Santak1Class.command[10] = "T";<br>
/* 80 */ Santak1Class.command[11] = "S";<br>
/* 85 */ Santak1Class.command[12] = "SR";<br>
/* 90 */ Santak1Class.command[13] = "C";<br>
/* 95 */ Santak1Class.command[14] = "CT";<br>
/* 100 */ Santak1Class.command[15] = "CB";<br>
/* 105 */ Santak1Class.command[16] = "PE";<br>
/* 110 */ Santak1Class.command[17] = "PD";<br>
/* 116 */ Santak1Class.command[18] = "QMT";<br>
/* 122 */ Santak1Class.command[19] = "F";<br>
/* 128 */ Santak1Class.command[20] = "WH";<br>
/* 134 */ Santak1Class.command[21] = "Q2";<br>
/* 140 */ Santak1Class.command[22] = "WA";<br>
/* 145 */ Santak1Class.command[23] = "WH";<br>
/* 150 */ Santak1Class.command[24] = "QA";<br>
/* 156 */ Santak1Class.command[25] = "FLT";<br>
/* 162 */ Santak1Class.command[26] = "FLT,00";<br>
/* 170 */ Santak1Class.command[27] = "QS";<br>
/* 176 */ Santak1Class.command[28] = "CTL";<br>
/* 182 */ Santak1Class.command[29] = "LT?";<br>
<br>
A list of commands but no description. Interestingly, the Q7 which
produces some output is not mentioned. .<br>
<br>
Due to my limited programming skills I was soon stuck, so I
decided to look at Nut drivers source to find out if there are any
that use similar commands. After a bit of experimenting I found
that 'blazer_ser' pretty much does what it's supposed to do. Also
most of the 'upsc' output looks reasonable:<br>
<br>
battery.voltage: 252.00<br>
battery.voltage.nominal: 240.0<br>
beeper.status: disabled<br>
device.type: ups<br>
driver.name: blazer_ser<br>
driver.parameter.cablepower: none<br>
driver.parameter.pollinterval: 2<br>
driver.parameter.port: /dev/ttyS0<br>
driver.version: 2.6.0<br>
driver.version.internal: 1.51<br>
input.current.nominal: 27.0<br>
input.frequency: 50.0<br>
input.frequency.nominal: 50<br>
input.voltage: 236.0<br>
input.voltage.fault: 140.0<br>
input.voltage.nominal: 220<br>
output.voltage: 220.0<br>
ups.delay.shutdown: 30<br>
ups.delay.start: 180<br>
ups.load: 1<br>
ups.status: OL<br>
ups.temperature: 31.5<br>
ups.type: online<br>
