.SH "NAME"
|
|
richcomm_usb \- Driver UPS equipment using Richcomm dry\-contact to USB solution
|
|
.SH "NOTE"
|
|
.sp
|
|
This man page only documents the specific features of the richcomm_usb driver\&. For information about the core driver, see \fBnutupsdrv\fR(8)\&.
|
|
.SH "SUPPORTED HARDWARE"
|
|
.sp
|
|
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 \fBgenericups\fR(8)\&.
|
|
.SH "BUGS"
|
|
.sp
|
|
Most contact\-closure UPSes will not power down the load if the line power is present\&. This can create a race when using secondary \fBupsmon\fR(8) systems\&. See the \fBupsmon\fR(8) man page for more information\&.
|
|
.sp
|
|
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\&.
