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.
