SpectralLED® RS-7 USER MANUAL Page 454.4 Spectral Operations4.4.1 - WLR - Set Wavelength RangeSets or reports the operating wavelength range for spectral operations, including spectral data transfers to andfrom the RS-7.Syntax:WLR [startWL],[endWL] set wavelength range [startWL] to [endWL]WLR report currently set wavelength rangewhere [startWL] and [endWL] are integers between 360 and 1100, representing nanometers, with [startWL] <[endWL].The wavelength range is applicable for the following commands:OSP Output spectrumTSP Target spectrumFTS Fit to TSPREP Report RMS Error % OSP vs. TSPExamples:wlr report current operating wavelength range380,780wlr380,920 extend wavelength range to 920 nmOk4.4.2 - STM - Spectrum Transfer ModeEstablishes the format for spectral data transfers between the host & RS-7. Spectral data is always 1 nm-stepresolution, units being μW/cm²/nm (irradiant source, see CTY & IRR) or μW/cm²/nm/sr (radiant source, see CTY& IRR) and is transferred between the host and RS-7 over the wavelength range set by WLR.Syntax:STM [0|1|2] set spectral transfer mode to 0, 1, or 2STM report current spectral transfer modewhere spectral transfer mode 0 is comma-delimited ASCII data, spectral transfer mode 1 is delimitedASCII data (columnar), and spectral transfer mode 2 is packed binary. The packed binary format is capable oftransferring a complete set of spectral data over the full wavelength range of 380 to 1100 nm at 115,200 baud in125 milliseconds.When transferring in packed binary format1. first an ASCII float representing a scale factor is sent
