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.
