PROTOCOL SERIAL COMMANDS

example, the master sets the current output high weight for an STXplus at address 01 assuming

a format of 2(X.) to14865.

‘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.
