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(8) for serial communication, or use the USB port, if available, with the usbhid- ups(8)] 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.
