NOTE ABOUT HISTORIC NUT RELEASE

Note
Two NUT websites

This version of the page reflects NUT release v2.8.1 with codebase commited 4ba352d8f at 2023-10-31T21:46:20+01:00

Options, features and capabilities in current development (and future releases) are detailed on the main site and may differ from ones described here.

NOTE

This man page only documents the specific features of the richcomm_usb driver. For information about the core driver, see nutupsdrv(8).

SUPPORTED HARDWARE

The Richcomm dry-contact to USB solution is a generic interface that is used to upgrade an existing (RS-232) contact closure UPS interface to USB. As such, all the limitations of the underlying contact closure interface apply. This means that you will only get the essentials in ups.status: OL, OB, and LB. See also genericups(8).

BUGS

Most contact-closure UPSes will not power down the load if the line power is present. This can create a race when using secondary upsmon(8) systems. See the upsmon(8) man page for more information.

The solution to both of these problems is to upgrade to a smart protocol UPS of some kind that allows detection and proper load cycling on command.
