All AvaSpec spectrometers with USB2 platform can work in stand-alone mode. The stand-alone mode was developed for process control applications, in which the spectrometer should output analog or digital signals, that can be directly coupled to Programmable Logical Controlers (PLC) in a process Control environment.
In order to get the desired stand-alone functionality of a spectrometer it is important to define functions, in which the parameters that need to be controlled can be measured.
These functions can be defined as (max. 8) History Channel Functions and the output values as 8 digital TTL-functions for which thresholds can be set using the AvaSoft-PROC process control software. Also 2 functions can be used to output an 8-bit analog value in the 0-5V Voltage range.
After a successful implementation in a PC connected spectrometer, Avantes can be contacted to implement the desired functions into the firmware on-board of the USB2 platform spectrometer. Since most functionality is custom-specific, please contact our technical sales-department for more information on this.
Optionally an on-board SDcard can be installed to save spectra on the card and download later to the PC.
