cable

  2. Plug the USB-to-serial converter cable into a free USB port on the host computer.
    Windows® detects the cable and assigns a COM port number.
    NOTE: If Windows® does not detect the cable, insert the accompanying mini-CD to load the driver.

  3. Attach the RS-232-to multiplexer cable to the  RS-232C connector on the back of the multiplexer.

Potentiostat NOTE: Reference 3000 potentiostats also require a special Y-shaped adapter.

  5. Connect the power cord to the rear of the multiplexer. Connect the other end of the power cable to the AC supply (mains).

A window asks you to restart Framework.

11 Click the OK button.
Connect the included cell cables to the desired channels on the back of the multiplexer, then restart Framework.
12. In the Framework software, run the desired multiplexed experiment.
13. Activate the checkboxes corresponding to the active channels on the multiplexer.

checkboxesWhen a particular channel runs, the amber LED for that channel illuminates.

NOTE: For AC experiments (e.g., EIS), you must run AC calibration of your potentiostat with the multiplexer connected. Do not run DC calibration.
To AC-calibrate multiplexer channels:

  1. Choose Experiment > Utilities > Multiplexer Configure and Test, as in step 8 in the previous section. The Select Function window appears.

  3. In the Active Cell area, choose a radio button for any channel to be calibrated, and click the OK button.
    NOTE: You only need to run AC calibration on one channel. All other channels are treated the same.GAMRY INSTRUMENTS ECM8 Electrochemical Multiplexer -

WHAT DOES GAMRY SOFTWARE DO?

| Gamry Framework TM
Controls your Gamry potentiostat for advanced and flexible data acquisition. Select from standardized experiments that are grouped by research type or use the Sequence Wizard to build complex automated experiments.
---|---
Echem Analyst TM
Quick and easy data analysis. Open your data files with Echem Analyst to perform specialized analysis algorithms and produce high-quality plots. Plots can be customized, overlaid, and scaled, or data can be exported for use in other plotting programs.
My Gamry Data TM
The default data folder location for Gamry Framework data files. You will find a shortcut on your desktop after installation. The data folder location can be changed within Gamry Framework by selecting Options > Path.

We have a variety of resources available to help you get started.
