APPENDIX B: KISTLER-MORSE

PROTOCOL SERIAL COMMANDS

‘o’ Command — Default Calibration Constants Only

This command is sent by the master to request the STXplus to default only the calibration

constants. For this example, the master requests the STXplus at address 01 to default its

calibration constants.

‘i’ Command — Default STXplus

This command is sent by the master to request the STXplus to reset to default conditions. For

this example, the master requests the STXplus at address 01 to default itself.

‘H’ Command — Perform HI Span Calibration

This command is sent by the master to request the STXplus calibrate its current input A/D to

correspond with the engineering units value that was sent by the master by adjusting it’s HI Span

calibration points. The range of this value can be ±2,147,483,647. The response from the

STXplus will be a single digit status where 0 for successful, 1 for successful but there was a less

than desirable difference between the HI Span and LO Span values, or 2 for successful but the HI

Span value was less than the LO Span value. For this example, the master sends the STXplus at

address 01 a value of 14356.2 assuming that the format is set to 3(X.X).

‘L’ Command — Perform LO Span Calibration

This command is sent by the master to request the STXplus calibrate its current input A/D to

correspond with the engineering units value that was sent by the master by adjusting it’s LO

Span calibration points. The range of this value can be ±2,147,483,647. The response from the

STXplus will be a single digit status where 0 for successful, 1 for successful but there was a less

than desirable difference between the HI Span and LO Span values, or 2 for successful but the HI

Span value was less than the LO Span value. For this example, the master sends the STXplus at

address 01 a value of -96700. assuming that the format is set to 0(X00.) and the difference

between the HI Span and the LO Span values was less than desirable.
