NAME

richcomm_usb − Driver UPS equipment using Richcomm dry−contact to USB solution

NOTE

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

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.
