SERIAL DATA FORMATS
Weight-On-Demand
If the Continuous Output for the serial port was not selected, Cont=no, then a computer
connected to the serial port can send a request for the 185 to transmit weight data. This is
known as Weight-On-Demand. There are two formats for weight on demand: ENQ and SMA
weight request.
ENQ Format
The host computer sends:
ENQ - (hex 05)
The 185 will respond:
<s><xxxxxx><d><_><uu><_><m><_><cc><_><cr>
where:
s = Sign "-" = negative, “ “ (space) for zero and above
xxxxxx.xxx = Weight Six digits
d = Decimal point Embedded in the weight, if enabled in setup
_ Space
uu = Units LB, KG, OZ, or G^, ^ = space
m = Mode G for gross or N for net
cc = Weight Status OC for overcapacity
MO for unstable
CZ for center of zero
EE for weight not displayed, or two spaces
cr = Carriage Return (hex 0D)
SMA Format
