13           Note
14           This man page only documents the hardware-specific features of the
15           mge-utalk driver. For information about the core driver, see
16           nutupsdrv(8).
17

SUPPORTED HARDWARE

19       mge-utalk supports the following legacy units, using the MGE UTalk
20       protocol:
21
22       •   Pulsar ESV+
23
24       •   Pulsar ES+
25
26       •   Pulsar EL
27
28       •   Pulsar EX
29
30       •   Pulsar EXtreme
31
32       •   Comet EXtreme
33
34       •   Comet (Utalk Serial Card, ref 66060)
35
36       •   Galaxy (Utalk Serial Card, ref 66060)
37
38       This driver also support some newer models with backward UTalk
39       compatibility, such as Pulsar Evolution and Pulsar EXtreme C. As these
40       models also support the SHUT protocol, prefer mge-shut for serial
41       communication, or use the USB port, if available, with the usbhid-ups
42       driver.
43

EXTRA ARGUMENTS

45       This driver supports the following optional settings in the
46       ups.conf(5):
47
48       lowbatt=num
49           Set the low battery warning threshold at which shutdown is
50           initiated by upsmon(8).
51
52           The factory default value is 30 (in percent), and can be settable
53           depending on the exact model.
54
55       offdelay=num
56           Set the timer before the UPS is turned off after the kill power
57           command is sent (via the -k switch).
58
59           The default value is 20 (in seconds).
60
61       ondelay=num
62           Set the delay before the UPS is turned on, after the power returns.
63
64           The default value is 1 (in minutes).
65
66       oldmac
67           Set this flag if you are running Linux on an Oldworld Macintosh box
68           (all beige Apple Macintosh). This might also be needed for other
69           OSs (like *BSD) running on PowerMac.
70

KNOWN ISSUES

72   Repetitive timeout and staleness
73       Older models, such as ES/ESV ones, might report repetitive "data stale"
74       errors. This is due to the fact that these models don’t support too
75       much polling. To solve this problem, add "pollinterval=20" in ups.conf,
76       and change the value of MAXAGE to 25 in upsd.conf, and DEADTIME to 25
77       in upsmon.conf.
