STATUS ENQUIRY:
Computer:
Q1<cr>
UPS:
UPS status data stream, such as
(MMM.M NNN.N PPP.P QQQ RR.R S.SS TT.T b7b6b5b4b3b2b2b0<cr>
UPS status data stream:
(a)
Start byte
(
(b)
Input Voltage:
MMM.M
M is an integer number ranging from 0 to 9. The unit is volts.
(c)
Input Fault Voltage:
NNN.N
N is an integer number ranging from 0 to 9. Its purpose is to identify a
short duration voltage glitch that causes UPS to go to inverter mode. If this
occurs, input voltage will appear normal at query before glitch and will still
appear normal at next query.
The I/P fault voltage will hold the glitch voltage until next query. After the
query, the fault voltage will be same as voltage until next glitch occurs.
(d)
Output Voltage:
PPP.P
P is an integer number ranging from 0 to 9. The unit is volts.
(e)
Output Current:
QQQ
QQQ is an integer percent of maximum current, not an absolute value.
(f)
Input Frequency:
RR.R
R is an integer number ranging from 0 to 9. The unit is Hz.
(g)
Battery Voltage:
SS.S or S.SS
Actual battery voltage is provided in the form SS.S. The unit is volts.
(h)
Temperature:
TT.T
T is an integer number ranging from 0 to 9. The unit is degrees centigrade.
