[Nut-upsuser] MGE Evolution mge-utalk Driver Not Connected error

[Phil Harrison]

Hi All,

I have an mge pulsar esv 14+ rackmount UPS connected via straight
through serial cable to a USB to serial adaptor (My motherboard does
not have a native RS232 port).

I am running Ubuntu Server 9.04 x64, and nut 2.4.1-2ubuntu4 installed via APT.

I am getting the error:

Poll UPS [ups1 at localhost] failed - Driver not connected

My conf files:

(ups.conf)
[ups1]
driver=mge-utalk
port=/dev/ttyUSB0


(upsd.conf)
ACL all 0.0.0.0/0
ACL localhost 127.0.0.1/32

ACCEPT localhost
REJECT all

(upsd.users)
[monuser]
        allowfrom = localhost
        password = pass
        upsmon master


(upsmon.conf)
MONITOR ups1 at localhost 1 monuser pass master

SHUTDOWNCMD "/sbin/shutdown -h +0"

Here is my syslog output:

I am fairly sure the USB to serial adaptor is working correctly
according to dmesg:

[    8.939008] USB Serial support registered for generic
[    8.939032] usbserial: USB Serial Driver core
[    8.948625] USB Serial support registered for pl2303

[    8.960675] pl2303: Prolific PL2303 USB to serial adaptor driver


When I run:

sudo /lib/nut/mge-utalk -DDD -a ups1

I get:

Network UPS Tools - MGE UPS SYSTEMS/U-Talk driver 0.89 (2.4.1)
debug level is '3'
initinfo: 'Si 1' unavailable, switching to 'Si' command
Syst Stat ><
Batt Stat ><

... etc

Any help would be greatly appreciated.

Thanks,

Phil
