WIFI OPERATION, CONT.
TCP/IP Connection
Continuous output is available by TCP/IP connection to the scale’s IP address at port 10001.
The scale will transmit a single set of weight data each time the SMA weight request
<LF>W<CR> is received.
Each time the SMA weight request <LF>R<CR> is received, the scale will transmit
weight data continually until another SMA command is received.
SMA format for both command <LF>W<CR> and <LF>R<CR>.
<LF><s><r><n><m><f><xxxxxx.xxx><uuu><CR>
Where:
LF = Line feed (hex 0A) = Start of response message
s = Scale Status definition
Z = Center of Zero <xxxxxx.xxx>= 0.000
O = Over Capacity <xxxxxx.xxx>= +weight
U = Under Capacity <xxxxxx.xxx>= -weight
E = Zero Error (clears when the condition clears)
<space> = None of the above conditions
NOTE: For “E” error condition <xxxxxx.xxx>= —————
(center dashes) and “Z”, “O”, “U” is overridden
r = Range (“1”, “2”, “3”, etc.) always “1” for a single range
n = Mode of Operation (Gross/Net status)
G = Gross normal weight
T = Tare weight (in response to “M” command)
N = Net normal weight
g = gross weight in high-resolution
n = net weight in high-resolution
m = Motion status
M = Scale in Motion
<space> = Scale not in Motion
f = Future = Reserved for future or custom use
xxxxxx.xxx = Weight with a decimal point if necessary
uuu = Units = e. g. lb, kg
CR = Carriage Return (hex 0D) = End of response message
SMA Commands
Once a TCP/IP connection has been made to the scale, you can issue SMA commands to it.
The scale will respond to the SMA commands in the format shown in the Response column of
the WI-FI AND BLUETOOTH SMA COMMANDS table on pages 55 and 56 of this manual.
