PROTOCOL SERIAL COMMANDS

would only be in effect when in digital mode. This would be the A/D counts required in order for

a zero weight to occur. The range of this value can be ±8,388,607. For this example, the master

sets the digital zero counts for an STXplus at address 01 to14865.

‘R4’ Command — Read Digital Zero Weight

This command is sent by the master to request the STXplus to send the zero weight calibration

value which would only be in effect when in digital mode. This would be the weight that was

used to calculate/calibrate a digital zero counts. The range of this value can be ±2,147,483,647.

The default value is 0. For this example, the master requests the digital zero 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.

‘w4’ Command — Write Digital Zero Weight

This command is sent by the master to set the zero weight calibration value of an STXplus which

would only be in effect when in digital mode. This would force a re-calibration of the digital zero

counts value based on the A/D counts currently being read applied to the zero weight value

transmitted without changing the delta counts/delta weight slope. The range of this value can be

±2,147,483,647. For this example, the master sets the digital zero weight for an STXplus at

address 01 assuming a format of 2(X.) to14865.

‘R5’ Command — Read Digital High Span Counts

This command is sent by the master to request the STXplus to send the high span counts

calibration value which would only be in effect when in digital mode. This would be the A/D

counts paired with the digital high 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 8,388,607. For this example, the master requests the digital high span counts for an

STXplus at address 01 which returns 23475 counts and a checksum of 05.
