Reading
R
R
Indicates the scale is sending a reading. Immediately following is the value sent.
Example: <ESC><R>ESC><W0200.0<ESC>Nm<ESC>E
Weight
W
Wnnn.n
Patient weight (example: W02000 = 200.0). The scale returns the value 999.99 if the scale is over-
loaded or under loaded.
Height H Hnnn.n Patient height
BMI B Bnn.n Patient BMI
Units N Nc Indicates the unit of the values (m=metric, c=constitutional).
End of Packet
(EOP) E
E Indicates the end of the command.
Diagnostics
(request) A
Accc A request for a diagnostic test on parts of the scale (e.g. battery life, load cells).
Diagnostics
(response) Z
Zccc
The response of the diagnostics done on the scale. Values can include error codes to indicate a
problem with the scale; or, all zeros (Z000) to indicate proper functioning of the scale.
Control (set a
value) C
Cccc=c
Sets the value of the scale’s global settings.
Example: <ESC><CUOM=m><ESC><E sets the unit of measurement.
