Kistler-Morse KM STXPlus - Manual (Page 27)

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.
