OEM spectrometers: ASM-5216 Microprocessor board

The ASM-5216 board is based on a powerful 5216 Coldfire processor, running at 64 Mhz, 16-bit AD converter and USB2.0/RS232-interface. The ASM-5216 electronics board is part of the 3rd generation AvaSpec platform spectrometers.

Different detector types can be connected to the electronics board, such as TAOS Photo Diode Arrays ( TSL1401), Sony CCD detectors (ILX511, ILX554B), Toshiba CCD detectors (TCD-1304), Hamamatsu back-thinned CCD detectors (S9840, S11071, S7031), Hamamatsu (G92xx series) and Sensors Unlimited InGaAs NIR detectors. For the Hamamatsu back-thinned detector a separate power converter board is needed and for the detectors with TE cooling a separate TE controller board is needed. The board is equipped with a Samtec 60-pin Card edge connector with 12 programmable IO ports (3 DI, 9 DO), 2 analog out ports and 2 analog in ports. One digital out port is used for controlling the flash rate of an external Xenon strobe (AvaLight-XE), one digital out port is used to control external TTL-shutter devices, one digital output is reserved for external control for flashing a laser source in LIBS applications. One digital in is used for external hardware trigger. The AS-5216 board can be synchronized with other AS-5216 boards to control the simultaneous data-sampling of multiple channels, all connected to USB2.0 high speed interface. On-board signal processing allows data reduction to speed up scan transfer time. Data reduction can be achieved by defining a start and stop pixel and On-Board Averaging. The board can be operated by the extensive AS-5216-DLL with many functions to control the electronics board and data sampling parameters (see software section).
