The Model RS-DAQ Controller is a microprocessor-based standalone system integrator that controls both the Model S48D Illumination Source and the Model D48 Detector Module. The Controller interfaces with these components as part of a complete multiwavelength fluorescence system.  It can be programmed via a keypad or by RS-232 download.  This highly versatile controller supports machine control, pulse counting and analog data acquisition. For a more general discussion of this product, refer to our Product Overview page.

Features

• This versatile controller will operate the Model S48D Illumination Source and Model D48 Detector Module, either separately or together.  All modes of filter wheel control (Single, Multi and Mixed) are supported.
• It can be programmed using the front panel keypad or by RS-232 commands. Prompts for keypad programming are provided by a backlit LCD display.
• The Controller can be used to collect data from a photomultiplier (TTL pulse counting) and 8 analog channels.  Data is sent to a host computer via the RS-232 port.  With software, this controller will operate as a complete multiwavelength fluorescence and analog data acquisition system.
• After programming, wavelength filter switching and data acquisition can be implemented by a single TTL input or by RS-232 control.  This makes integration of this Controller into existing fluorescence systems a snap!
• A monitor port is provided to monitor the position of the filter wheel in the Model S48D Illumination Source and Model D48 Detector Module.  This is convenient for precisely synchronizing external events to wavelength filter changes.
• Provides a convenient method to add components to a fluorescence imaging system in manner that will not drain computer resources from the imaging system.

Programming

• A simple programming syntax is provided for RS-232 programming.  The following simple program will set the excitation filter wheel and light attenuator wheel in the Model S48D Illumination Source and the emission filter wheel in the Model D48 Detector Module to fixed positions:

InitializeSystem()
WheelIndex(ExEmNd,0,0,0)
WheelFixed(ExEmNd,8,4,4,3,100)
ResetMotor()

• RS-232 programming can be accomplished using any programming environment (Lab Windows, Lab View, Visual Basic, Visual C++, etc.).  RS-232 commands can also be sent to the Controller using a Terminal Emulation program.  C&L Instruments can provide complete Windows-based data acquisition software for this controller.
• A driver for LabVIEW is available.  This driver allows the user to assume complete control of our Model S48D Illumination Source and Model D48 Detector Module for instrument control and data acquisition using this popular graphical programming language developed by National Instruments Corporation.  Contact C&L Instruments for further details and availability.
