Appendix V-A: Selecting Alternate Start-Up Parameters
The following are the Start-Up parameters and their default values:
GRATING
#1
WAVELENGTH
0.0 nm
SCAN SPEED
100.0 nm/min
Each of the above may be changed through the RS-232 port or USB port using the following commands.
These values are stored in non-volatile memory and will be in effect after the next power-up.
INIT-GRATING Selects which of the two gratings on the installed turret the SP-2300i will go to after
finding 0.0 nm on the first grating.
e.g., 2 INIT-GRATING selects the second grating as the default
INIT-WAVELENGTH Sets an initial wavelength for the SP-2300i after initialization.
e.g., 435.84 INIT-WAVELENGTH Notice that two digits after the decimal point are
required.
INIT-SRATE Sets an initial scan rate for the SP-2300i.
e.g., 500.00 INIT-SRATE Notice that two digits after the decimal point are required
The following command is used to return all grating parameters and start-up parameters to the original factory
settings. Note: Any gratings installed at a later date (after initially receiving the SP-2300i) will be erased from
memory using this “restore command”.
RESTORE-FACTORY-SETTINGS Returns all parameters, including grating calibration parameters, to the
original factory calibrated settings. Note: This command will overwrite any calibration
parameters set by the user.
