|
.SH NAME
|
|
mge\(hyutalk \- Driver for MGE UPS SYSTEMS UTalk protocol hardware
|
|
.SH NOTE
|
|
This man page only documents the hardware\(hyspecific features of the
|
|
mge\(hyutalk driver. For information about the core driver, see
|
|
\fBnutupsdrv\fR(8).
|
|
|
|
.SH SUPPORTED HARDWARE
|
|
mge\(hyutalk 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.
|
|
|
|
.SH EXTRA ARGUMENTS
|
|
|
|
This driver supports the following optional settings in the
|
|
\fBups.conf\fR(5):
|
|
|
|
.IP "lowbatt=\fIvalue\fR"
|
|
Low battery level below which LB is raised, in % (default 30%)
|
|
|
|
.IP "ondelay=\fIvalue\fR"
|
|
Set delay before startup, in minutes (default 1 minute)
|
|
|
|
.IP "offdelay=\fIvalue\fR"
|
|
Delay before shutdown, in seconds (default 120 seconds)
|
|
|
|
.IP "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.
|
|
|
|
.SH IMPLEMENTATION DETAILS
|
|
|
|
Not all MGE UPS models provide all possible information, settings and commands.
|
|
mge\(hyutalk checks on startup which variables and commands are available from
|
|
the UPS, and re\(hyreads these regularly. Thus, startup is a bit slow,
|
|
but this should not matter much.
|
|
|
|
mge\(hyutalk.h defines a struct array that tells the driver how to read
|
|
variables from the UPS and publish them as NUT data.
|
|
|
|
"ups.status" variable is not included in this array, since it
|
|
contains information that requires several calls to the UPS and more
|
|
advanced analysis of the reponses. The function get_ups_status does
|
|
this job.
|
|
|
|
Note that MGE enumerates the status "bits" from right to left,
|
|
i.e., if buf[] contains the reponse to command "Ss" (read system
|
|
status), then buf[0] contains "bit" Ss.1.7 (General alarm), while
|
|
buf[7] contains "bit" Ss.1.0 (Load unprotected).
|
|
|
|
enable_ups_comm() is called before each attempt to read/write data
|
|
from/to the UPS to re synchronise the communication.
|
|
|
|
.SH KNOWN ISSUES
|
|
.SS "Repetitive stale status \(hy Loss of communication"
|
|
|
|
Older models, such as ES/ESV ones, might report repetitive "data stale"
|
|
errors. This is due to the fact that these models doesn'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.
|
|
|
|
.SH TODO LIST
|
|
|
|
.IP "Sort out OFF/OL issues"
|
|
OFF is set according to Ls.2.7, but maybe this interpretation is in
|
|
conflict with the NUT interpretation of the OFF flag?
|
|
|
|
.IP "Add PowerShare / PowerSave support (selectable plug number for commands)"
|
|
ON/OFF/REBOOT commands can act either on outlet 1, 2 or main (1 + 2). This
|
|
features depends on the UPS model. This would also allow to support
|
|
UM\(hySwitch (smart outlet).
|
|
|
|
.IP "Enhance the model name exposure"
|
|
A table, named Si1_models_names, has been created to format finelly the
|
|
UPSs model names, but it is not yet being used.
