Parallel Light Engine Performance monitoring Using the Onboard Control GUI
AURA, CELESTA, RETRA, SPECTRA, and ZIVA Light Engines incorporate a control GUI accessed through a web browser via an ethernet connection. Image acquisition applications used to control the light engine though connection of either the USB or RS232 serial ports can be run in parallel with ethernet-connected control GUI to aid in trouble-shooting. As shown in Figure 1, this allows the light engine to be controlled by the image acquisition software, while the GUI serves as a passive monitor of the light engine status.
The control GUI displays many types of information pertinent to the performance of the light engine that are not accessible in current releases of most image acquisition software packages. These include:
- Real-time light output power readouts
- Standby mode status
- Light engine operating software error messages
- Humidity/dew point data
- Serial port configuration
- TTL port configuration
- Cumulative run time data
In cases where the PC being used for image acquisition control has a single ethernet port that is dedicated to internet access, a USB-to-ethernet adapter (Figure 2) can be used for connection to the light engine control GUI. USB-to-ethernet adapters are readily available from online vendors for less than $20.
