Bio-Rad BioLogic Signal Import Module (SIM) - Manual (Page 15)

2.1 CONTROLLER AND USB BITBUS COMMUNICATOR
The DuoFlow system is controlled by a PC computer, referred to throughout this document as the Controller.
The Dell Controller available from Bio-Rad includes a color display monitor, a keyboard, a mouse device, a
CD-ROM drive, and a floppy disk drive. The Controller communicates with the workstation and other
external devices through its USB connector. The USB Bitbus Communicator serves as the link between the
Controller’s USB port and the DuoFlow’s instrument bus. This link allows the Controller to control the
Maximizer and Workstation, as well as any devices connected to the Maximizer or Workstation, such as
automatic valves, UV detector and conductivity monitor, and peripheral instruments such as the BioFrac
fraction collector, the QuadTec UV/Vis detector, the Model EP-1 Econo pump, the Econo Gradient Pump
(EGP), and Signal Import Modules (SIM).
2.1.1 Controller
The Controller runs the BioLogic DuoFlow software (version 4.0 or higher) on a Windows ® 2000 operating
system. From the Controller you can set up and run methods, perform simple data analysis, and store
method and run data. The following tables show the key features on the Dell computer provided by Bio-Rad.
