NAME
The essence of a UPS definition in this driver is how it uses the serial lines that are available. These are the abbreviations you will see below:
OL
On line (no power failure) (opposite of OB - on battery)
LB
Low battery
SD
Shutdown load
CP
Cable power (must be present for cable to have valid reading)
CTS
Clear to Send. Received from the UPS.
RTS
Ready to Send. Sent by the PC.
DCD
Data Carrier Detect. Received from the UPS.
RNG
Ring indicate. Received from the UPS.
DTR
Data Terminal Ready. Sent by the PC.
ST
Send a BREAK on the transmit data line
A "-" in front of a signal name (like -RNG) means that the indicated condition is signaled with an active low signal. For example, [LB=-RNG] means the battery is low when the ring indicate line goes low, and that the battery is OK when that line is held high.
RPT Repoteck RPT-800A/RPT-162A
[CP=DTR+RTS] [OL=DCD] [LB=-CTS] [SD=ST]
genericups - Driver for contact-closure UPS equipment
NOTE
This man page only documents the specific features of the genericups driver. For information about the core driver, see nutupsdrv(8).
SUPPORTED HARDWARE
This driver supports hardware from many different manufacturers as it only uses the very simplest of signaling schemes. Contact closure refers to a kind of interface where basic high/low signals are provided to indicate status. This kind of UPS can only report line power and battery status.
This means that you will only get the essentials in ups.status: OL, OB, and LB. Anything else requires a smarter UPS.
CABLING
Cabling is different for every kind of UPS. See the table below for information on what is known to work with a given UPS type.
