‘RA’ Command — Read Current Output Low Weight
This command is sent by the master to request the STXplus to send the current output low
weight calibration value. 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 be obtained (refer to
commands “n2”/”m2” for current output range). The range of this value can be ±8,388,607 in
analog mode and ±2,147,483,647 in digital mode. The default value is 0. For this example, the
master requests the current output low weight for an STXplus at address 01 assuming it is in
digital mode and using a format of 3(X.X), which returns 347.5 engineering units and a checksum
of EB.

‘wA’ Command — Write Current Output Low Weight
This command is sent by the master to set the current output low weight calibration value of an
STXplus. 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 be obtained (refer to commands
“n2”/”m2” for current output range). The range of this value can be ±2,147,483,647. For this
example, the master sets the current output low weight for an STXplus at address 01 assuming
a format of 2(X.) to14865.

‘tH’ Command — Read Current Output Fail-safe Mode
This command is sent by the master to request the STXplus to send the current output fail-safe
mode. The range of acceptable values is 0-2 where 0 for no change, 1 for minimum current
output range, or 2 for maximum current range. The default value is 0 (no change). For this
example, the master requests the current output failsafe mode for an STXplus at address 01
which returns 0 (no change) and a checksum of 51.
