This document describes the installation of a single 850/890 test system that can be used for either PEM or DMFC configurations.

The FuelDual program described below is typically used to attach multiple 850/890 test stations to a single computer. In this case, it will be used to create multiple independent configurations for a single station.

Multiple startup icons will be placed on the desktop so that the system can be started in PEM or DMFC modes.

• Install the latest FuelCell release and test the system using the PEM hardware.
• Browse the FuelCell CD and locate the program fueldual38.exe
• Install FuelDual by running the above executable on a machine that has FuelCell and a GPIB interface installed.
• Follow the installer directions carefully!
• Destination Directory: Use the default setting (C:\FuelCell) unless the FuelCell program has been installed in a different location.
• Define Station #1: Select a new Station Name for the existing configuration, for example FuelCell-PEM. The GPIB Address and Reformer GPIB Address should match the existing configuration and should not be changed (the defaults are GPIB Address 7, Reformer GPIB Address 0).
• Define Station #1: Select a Station name for the new configuration, for example FuelCell-DMFC. Set the GPIB Address and Reformer Address to exactly match those used for Station #1 (normally 7 and 0).
• Select the proper model for Station #2: Select the model (current, voltage, power ratings) of the Load Unit. (If an 890B is selected you will be prompted for the Calibration disk. Put the 890B calibration floppy disk in the computer, and select the appropriate drive letter.)
• Start the FuelCell program using the FuelCell-DMFC icon and use File | Instrument Configuration… to select the fuel control hardware that is used for this configuration.

Note: The FuelDual installation process described above will create 2 identical, but independent software configurations. Each configuration is accessed by starting the FuelCell program using the appropriate icon on the desktop.

The following info can be used to manually setup multiple station configurations on a single PC:

• Create an extra Fuelcell desktop icon having alternate name (e.g. Fuelcell-DMFC)
• Modify the Tartget of the new Icon to: C:\fuelcell\Fuelcell.exe /station x (where x is 1, 2, 3 etc)
• Create copies of the fuelcell.ini and reform.ini files called fuelcellx.ini and reformx.ini (where x matches the number chosen above)
• Repeat above steps for each hardware configuration you wish to accommodate (if different test systems are being configured - different serial numbers - then the fuelcellx.ini and reformx.ini files will need to be created for each serial number, and not copied from the original fuelcell.ini file).
