Command “n”:
@AA.a
Sync character (@) and unit address, AA = Unit ID (0 to 99; 0 is a global ID), a
(channel)
n0
Command character and Type
– 0=read, 1=set(n/a), 2=activate(n/a), 3=ack, 4=nak
#11,
Number of fields character and number of fields after the comma, excluding CRC
3000,
Forward Amp Rating (amps)
1
fir
12,
Forward Volt Rating (volts)
1
fvr
3000,
Channel operate time
– minutes
1
topr
12345,
channel amp hours
1
ahr
2,
Totalizer Units (0=reserved, 1=Amp Min, 2= Amp Hr)
tu
0,
Totalizer Resolution (0=xxxx, 1=xxx.x, 2=xx.xx, 3=x.xxx)
tr
1234,
Totalizer Value
– units are dependent on the totalizer settings in the setup command
1
tot
0,
Clear Totalizers (0 = no action, 1 = set forward and reverse totalizer values to zero)
The action of setting this parameter to ‘1’ clears the totalizers, the value of this
parameter is not stored and will always be read as zero.
tclr
1234,
Reverse Totalizer Value
– as a positive number, units are dependent on the totalizer
settings in the setup command
1

Notes:
1. The channel current ratings, voltage ratings, operate time, amp hours, and totalizer value are read
only values. Writing to these locations will have no affect.
2. Changing the totalizer units or resolution will cause the totalizer value to be reset to zero. The
t
otalizer can also be cleared by writing a ‘1’ to the “clear totalizer” field.
