‘wC’ Command — Write Analog Zero Counts
This command is sent by the master to set the zero counts calibration value of an STXplus which
is used to calibrate the current output engine. This would be the minimum A/D counts if
operating in analog mode or the minimum weight units if operating in digital mode (refer to
commands “n1”/”m1” for analog/digital mode) where the lowest portion of the current output
range would begin to change towards the highest portion of the current output range (refer to
commands “n2”/”m2” for current output range). The result of this command will be to
re-calculate/calibrate the current output low weight value (commands “RA/wA”) based on the
subtraction of current output high weight and analog delta counts. The range of this value can
be ±8,388,607 in analog mode and ±2,147,483,647 in digital mode. For this example, the master
sets the analog zero counts for an STXplus at address 01 assuming a format of 2(X.) to14865.

‘RD’ Command — Read Tare Weight
This command is sent by the master to request the STXplus to send the tare weight value. This
value would be the difference between gross weight and net weight. The range of this value can
be ±2,147,483,647. The default value is 0. For this example, the master requests the tare weight
for an STXplus at address 01 assuming a format of 3(X.X), which returns 347.5 engineering units
and a checksum of EB.

‘wD’ Command — Write Tare Weight
This command is sent by the master to set the tare weight value of an STXplus. This value
would be the difference between gross weight and net weight. The range of this value can be
±2,147,483,647. For this example, the master sets the tare weight for an STXplus at address 01
assuming a format of 2(X.) to14865.

‘aR’ Command — Read Averaging
This command is sent by the master to request the STXplus to send the averaging value. This
value is the number of running A/D samples that would be averaged together to produce a
filtered A/D output. The range of this value can be 0-100. The default value is 5. For this example,
