PROTOCOL SERIAL COMMANDS

which would only be in effect when in digital mode. This would be the A/D counts required in
order for a high span weight to occur. The result of this command if in 2-point calibration mode
or following a “w7”, “w8” or “L” command in slope-intercept calibration mode will be a
recalculation/calibration of the following 2 values. First, the digital delta counts value based on
the difference between the digital high span counts value and the digital low span counts value.
Secondly, the digital zero counts value based on the value in counts would occur when 0 weight
is displayed. The range of this value can be ±8,388,607. For this example, the master sets the
digital high span counts for an STXplus at address 01 to14865.

‘R6’ Command — Read Digital High Span Weight
This command is sent by the master to request the STXplus to send the high span weight
calibration value which would only be in effect when in digital mode. This would be the weight
that is paired with the digital high span counts that would serve as one point on the
calibration slope line if in 2-point calibration mode. The range of this value can be
±2,147,483,647. The default value is 9999. For this example, the master requests the digital high
span weight for an STXplus at address 01 assuming a format of 3(X.X), which returns 347.5
engineering units and a checksum of 01.

‘w6’ Command — Write Digital High Span Weight
This command is sent by the master to set the high span weight calibration value of an STXplus
which would only be in effect when in digital mode. This would be the weight that is displayed
when high span A/D counts is measured. The result of this command if in 2-point calibration
mode or following a “w7”, “w8” or “L” command in slope-intercept calibration mode will be a
recalculation/calibration of the following value. The digital delta weight value based on the
difference between the digital high span weight value and the digital low span weight value. The
range of this value can be ±2,147,483,647. For this example, the master sets the digital high
span weight for an STXplus at address 01 assuming a format of 2(X.) to14865.

‘R7’ Command — Read Digital Low Span Counts
This command is sent by the master to request the STXplus to send the low span counts
calibration value which would only be in effect when in digital mode. This would be the A/D
counts paired with the low span weight that would serve as one point on the calibration slope line
if in 2 point calibration mode. The range of this value can be ±8,388,607. The default value is 0.
