Data Format
(Continuous Output)
If
Cont
(continuous output) was selected, the scale will continuously transmit weight data in
SMA format (see below).
(Weight-On-Demand)
If
POLL
(Weight-On-Demand) was selected and the scale is connected to a host device
(computer) for transmission of weight data to a PC-based EMR (electronic medical record)
software program, it will transmit a single set of weight data each time the host device
(computer) sends a SMA weight request “W” or a weight request “ENQ” (hex 05). An
example and explanation of the data format transmitted is shown below.
(Cont or POLL)
This format is used if the scale is configured for
Cont
(continuous output) OR if the scale is
configured for
POLL
(weight-on-demand) and the host device (computer) sends:
<LF>W<CR>
or
<ENQ> (hex 05)
The scale will respond with the following SMA weight string:
<LF>S1GM^DDDDDDDDDDUUU<CR>
Where:
LF =
Line Feed
Line feed character (hex 0A)
S =
Status
O = Over Cap, Z = Center Zero,
U =
Below Zero, E = Error
1 =
the number 1
G =
Mode of operation
G = Gross, N = Net, T = Tare
M =
Motion bit
M = Motion, “ “
(blank)
= Settled (no motion)
^ =
Space
DDDDDDDDDD = Weight
Weight with decimal point if necessary
UUU =
Units
e. g. lb, kg
CR =
Carriage Return
Carriage Return (hex 0D)
