mge-utalk - Driver for MGE UPS SYSTEMS UTalk protocol equipment
This man page only documents the hardware-specific features of the mge-utalk
driver. For information about the core driver, see nutupsdrv
mge-utalk supports the following legacy units, using the MGE UTalk protocol:
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.
This driver supports the following optional settings in the ups.conf
Set the low battery warning threshold at which shutdown
is initiated by upsmon
The factory default value is 30 (in percent), and can be settable depending on
the exact model.
Set the timer before the UPS is turned off after the kill
power command is sent (via the -k
The default value is 20 (in seconds).
Set the delay before the UPS is turned on, after the
The default value is 1 (in minutes).
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.
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.
