NUTDRV_ATCL_USB(8) NUT Manual NUTDRV_ATCL_USB(8)NAMEnutdrv_atcl_usb - Driver for 'ATCL FOR UPS' equipment
NOTE
This man page only documents the specific features of the
nutdrv_atcl_usb driver. For information about the core driver, see
nutupsdrv(8).
SUPPORTED HARDWARE
This driver is for UPS hardware which identifies itself as USB idVendor
0001 and idProduct 0000, and iManufacturer ATCL FOR UPS. Known
manufacturers include Kanji and Plexus. The UPS interface seems to be a
USB frontend to a traditional contact-closure interface, which
translates into only three states in ups.status: OL, OB and OB LB. See
also genericups(8).
EXTRA ARGUMENTS
This driver supports the following optional setting:
vendor=name
In case your iManufacturer (Vendor) string does not exactly match
ATCL FOR UPS, you may provide an alternate string here. Note that a
more likely case is that your device is handled by another driver
for 0001:0000 devices, such as nutdrv_qx(8).
BUGS
The UPS returns the same code for "load power is off" as for "on line
power". This condition will not be observed if the NUT master is
powered by the UPS, but may be an issue if the UPS is monitored by a
remote system.
The time between the shutdown command and removal of power seems to be
fixed at 30 seconds. Ensure that the NUT shutdown script is invoked as
late as possible in the shutdown procedure (in case some services take
longer than others to clean up).
Most contact-closure UPSes will not power down the load if the line
power is present. This can create a race when using slave upsmon(8)
systems. See the upsmon(8) man page for more information. The solution
to this problem is to upgrade to a smart protocol UPS of some kind that
allows detection and proper load cycling on command.
