hello everyone,<br>I've been testing the NUT solution as opposed to the undocumented LanSafe application to control my Eaton UPS.<br><br>I am on a Slackware 13.37 system with a 2.6.37.6 kernel. NUT version is 2.4.3 .<br>
I installed the tarball by compiling it directly on my system (as a slackbuild package).<br>The UPS is an Eaton Powerware 9155, but I don't know how to obtain the manufacturing date. The unit was bought sometime in 2006-2007 though.<br>
<br>The unit has a serial interface to communicate with a pc, and I am using a usb-serial converter to connect it there. dmesg shows:<br><br>usb 6-2: new full speed USB device using uhci_hcd and address 3<br>usb 6-2: New USB device found, idVendor=067b, idProduct=2303<br>
usb 6-2: New USB device strings: Mfr=1, Product=2, SerialNumber=0<br>usb 6-2: Product: USB-Serial Controller<br>usb 6-2: Manufacturer: Prolific Technology Inc.<br>pl2303 6-2:1.0: pl2303 converter detected<br>usb 6-2: pl2303 converter now attached to ttyUSB0<br>
<br>This converter appears to the system as /dev/ttyUSB0. But I presume for all practical purposes I should assume that this is just another serial port (correct me if that's wrong).<br><br>My ups.conf looks line:<br>
<br> [DSAups]<br> driver = bcmxcp<br> port = /dev/ttyUSB0<br> desc = "Eaton Powerware 9155"<br><br>I have ALSO attempted to run the drivers: bcmxcp-usb, upscode2, usbhid-ups (just in case the /dev/ttyUSB0 is actually a USB look-alike port rather than serial look-alike one) to no avail.<br>
<br>the debug output is the following:<br><br>root@samothraki:/usr/libexec/nut# ./bcmxcp -DDDDD -a DSAups<br>Network UPS Tools - BCMXCP UPS driver 0.23 (2.4.3)<br>RS-232 communication subdriver 0.17<br> 0.000000 send_to_all: SETINFO driver.parameter.port "/dev/ttyUSB0"<br>

root@samothraki:/usr/libexec/nut#<br><br><br>Looks fairly dead to me as if theere was smth wrong with the cables. So I installed a windows server 2008 virtual machine (on virtualbox) and attached the /dev/ttyUSB0 to the virtual machine. There I installed the LanSafe application provided by Eaton and voila, the system was working.<br>
<br>So there is something else going on here, directly on the host, which I can't understand.<br>Any ideas?<br><br>Thank you in advance for your help<br>Nass<br><br>
