Start byte
b
MMM.M
Input voltage
M is an Integer number 0 to 9. The units is V.
c
HH.H
Input frequency
H is an Integer number 0 to 9. The units is Hz.
d
LLL.L
Output voltage
L is an Integer number 0 to 9. The units is V.
e

DDD
Output load percent
For Off-line UPS: DDD is a percent of maximum VA,
not an absolute value.
For On-line UPS: DDD is Maximum of W% or VA%.
VA% is a percent of maximum VA.
W% is a percent of maximum real power.
j
