6 optiups - Driver for Opti-UPS (Viewsonic) UPS equipment
7
9 This man page only documents the hardware‐specific features of the
10 bestups driver. For information about the core driver, see nutups‐
11 drv(8).

15 optiups was originally written against a PowerES 280es in nut-0.45. It
16 was revised for nut 2.0.1 and tested against a PowerES 420E. It is
17 expected to work with at least the PowerES, PowerPS, and PowerVS mod‐
18 els.
19
20 This driver will not work with the PowerES stock serial cable. You
21 will need to construct your own three conductor cable:
22
23 UPS 6 -> PC 3
24 UPS 9 -> PC 2
25 UPS 4 -> PC 5
26
27
29 This driver supports the following optional settings in the
30 ups.conf(5):
31
32
33 status_only
34
35 Only poll for critical status information. Without this,
36 optiups (and all nut drivers) poll all sorts of information from
37 the UPS fairly often. It is probably not often enough to hurt
38 anything, so this option probably is not very useful, unless you
39 have a flaky serial connection or a highly loaded machine.
40
41
42 nowarn_noimp
43
44 Does not print warnings when the UPS reports that a variable is
45 not implemented or not pollable. Without the option you will
46 get a message sent to your system logs each time nut polls the
47 ups. If you specify nowarn_noimp, this message will only be
48 logged once.
49
50
51 fake_lowbatt
52
53 This forces the low battery flag true. Without it, if you want
54 to test your UPS, you will have to unplug it and wait until the
55 battery drops to a low/critical voltage level before nut will
56 respond and power down your system. With the flag, nut should
57 power down the system soon after you pull the plug. When you
58 are done testing, you should remove this flag.
59
60
62 On the 420E, ups.serial and ups.temperature are unsupported features.
63 This is not a bug in nut or the nut driver, just the way things are
64 with this UPS.
