mge-utalk - Driver for MGE UPS SYSTEMS UTalk protocol equipment
mge-utalk -a UPS_NAME [OPTIONS]
This man page only documents the hardware-specific features of the mge-utalk driver. For information about the core driver, see nutupsdrv(8).
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.
This driver supports the following optional settings in the ups.conf(5):
Set the low battery warning threshold at which shutdown is initiated by
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
The default value is 20 (in seconds).
Set the delay before the UPS is turned on, after the power returns.
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.
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.
