MGE-UTALK(8) NUT Manual MGE-UTALK(8)NAME
mge-utalk - Driver for MGE UPS SYSTEMS UTalk protocol equipment
SYNOPSIS
mge-utalk -h
mge-utalk -a UPS_NAME [OPTIONS]
Note
This man page only documents the hardware-specific features of the
mge-utalk driver. For information about the core driver, see
nutupsdrv(8).
SUPPORTED HARDWARE
mge-utalk supports the following legacy units, using the MGE UTalk
protocol:
Pulsar ESV+,
Pulsar ES+,
Pulsar EL,
Pulsar EX,
Pulsar EXtreme,
Comet EXtreme,
Comet (Utalk Serial Card, ref 66060),
Galaxy (Utalk Serial Card, ref 66060).
This driver also support some newer models with backward UTalk
compatibility, such as Pulsar Evolution and Pulsar EXtreme C. As these
models also support the SHUT protocol, prefer mge-shut for serial
communication, or use the USB port, if available, with the usbhid-ups
driver.
EXTRA ARGUMENTS
This driver supports the following optional settings in the
ups.conf(5):
lowbatt=num
Set the low battery warning threshold at which shutdown is
initiated by upsmon(8).
The factory default value is 30 (in percent), and can be settable
depending on the exact model.
offdelay=num
Set the timer before the UPS is turned off after the kill power
command is sent (via the -k switch).
The default value is 20 (in seconds).
ondelay=num
Set the delay before the UPS is turned on, after the power returns.
The default value is 1 (in minutes).
oldmac
Set this flag if you are running Linux on an Oldworld Macintosh box
(all beige Apple Macintosh). This might also be needed for other
OSs (like *BSD) running on PowerMac.
KNOWN ISSUES
Repetitive timeout and staleness
Older models, such as ES/ESV ones, might report repetitive "data stale"
errors. This is due to the fact that these models don’t support too
much polling. To solve this problem, add "pollinterval=20" in ups.conf,
and change the value of MAXAGE to 25 in upsd.conf, and DEADTIME to 25
in upsmon.conf.
