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.
