[Nut-upsuser] Problems with MGE ESV 8+ and NUT 2.0.3

[Daniel Johansson]

Hello, I recently had a failure with my old MGE ESV8 ups, it just died 
on me so I had to get a new one. I found a MGE ESV8+ cheap and 
everything seems to work fine with it except the communication with the 
computer. The old ESV8 (non +) worked fine with NUT after applying some 
patches I got from the mailing list, but I think they are in the source 
tree now. I'm using the same cable that worked with my old ups, as it's 
the same protocol mge-utalk and same cable to the new ups.

I'm running FreeBSD 6.1 amd64 with NUT 2.0.3 installed from ports and my 
problem is that I can't seem to get any data out of the UPS.

When starting upsd I get this:
Network UPS Tools - UPS driver controller 2.0.3
Network UPS Tools - MGE UPS SYSTEMS/U-Talk driver 0.87 (2.0.3)
Could not get multiplier table: using raw readings.
.Detected Si on /dev/cuad0
updateinfo: Cannot update system status
Starting nut.
Network UPS Tools upsd 2.0.3
Connected to UPS [ups]: mge-utalk-cuad0
Synchronizing........ giving up

and my message log is filled with:
Jun 29 13:14:12 zeus mge-utalk[78111]: updateinfo: Cannot update system 
status
Jun 29 13:14:12 zeus upsd[78121]: Data for UPS [ups] is stale - check driver
Jun 29 13:14:13 zeus upsd[78121]: UPS [ups] data is no longer stale

Jun 29 13:14:23 zeus upsd[78121]: UPS [ups] data is no longer stale

I'm able to run upsc but I get no data out of the ups:
battery.charge: 000.0
battery.charge.low: 00
battery.runtime: 00000
battery.voltage: 000.0
battery.voltage.nominal: 000.0

ups.load: 000.0
ups.mfr: MGE UPS SYSTEMS
ups.model: Si
ups.status:
ups.temperature: 000.0
ups.test.interval: 000

This is what my conf files looks like..
ups.conf:
[ups]
        driver = mge-utalk
        port = /dev/cuad0
        desc = "MGE Pulsar ESV 8+"

upsd.conf:
ACL all 0.0.0.0/0
ACL localhost 127.0.0.1/32
ACL localnet 192.168.1.0/24

ACCEPT localhost
ACCEPT localnet
REJECT all


Any ideas what I can do to get this to work? MGE ESV8+ should be 
supported, right? My ESV8 worked just fine. I'm glad for all help I can get.
