‘m1’ Command — Write Analog/Digital Mode Flag
This command is sent by the master to set the analog/digital mode of an STXplus. The range of
acceptable values is 0-1 where 0 for calibrated in analog mode or 1 for calibrated in digital mode.
For this example, the master sets the mode for an STXplus at address 01 to the mode of 0
(analog mode). Any of the 6 leading zeros may be omitted.

‘n2’ Command — Read Output Current Range
This command is sent by the master to request the STXplus to send the range of the current
output. The range of returned values is 0-3 where 0 for 4-20mA, 1 for 0-20mA, 2 for 20-4mA, or
3 for 20-0mA. The default value is 0 (4-20mA). For this example, the master requests the
current output range for an STXplus at address 01 which returns the range of 1 (0-20mA) and a
checksum of 51.

This command is sent by the master to set the current output range of an STXplus. The range of
acceptable values is 0-3 where 0 for 4-20mA, 1 for 0-20mA, 2 for 20-4mA, or 3 for 20-0mA. For
this example, the master sets the current output range for an STXplus at address 01 to the mode
of 3 (20-0mA). Any of the 6 leading zeros may be omitted.

‘R1’ Command — Read Digital Delta (Scale Factor) Counts
This command is sent by the master to request the STXplus to send the delta counts calibration
value which would only be in effect when in digital mode. This would be the A/D counts delta
required in order for a weight delta to occur. The default value is 8,388,607. The range of this
value can be ±8,388,607. For this example, the master requests the digital delta counts for an
STXplus at address 01 which returns 923475 counts and a checksum of 3E.
