RICHCOMM_USB(8)			  NUT Manual		       RICHCOMM_USB(8)

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).

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.
