Information here is specific to one or more of Gamry's retired lineup: PC3, PC4, PCI4, FAS 1 & 2, and the Series G. Any issues that could also apply to Reference or Interface instruments (Framework, Analyst, toolkit, cell cables) will be found in another section.
When installing a second ECM8, or switching to a USB-to-Serial adapter for your ECM8 or TDC4, it is necessary to manually change the Port number in the Gamry.INI file. The correct Port number allows the Framework Software to communicate properly with the Gamry Hardware device. The INI file is accessible from the Windows Start Menu under Gamry / Framework / Gamry.ini. The file will open in your default text editor program.
A Gamry PC4 can often outlive the computer into which it was first installed. PC4 potentisotats require a computer with two adjacent ISA slots. They are not plug-and-play equipment and require some settings tweaking to get them up and running. Here are two common problems that are received when launching the Gamry Framework for the first time after installation:
The symptom is that at the start of the experiment no data acquisition begins and the runner window displays â€œAutorangingâ€ in the lower left hand corner. This applies only to PCI potentiostats installed inside a desktop computer. Verify that the 4-pin power cables are connected to the control board and potentiostat board inside the computer. The instrument will still be properly recognized by the computer without the power cables connected but no signal generation or data acquisition can occur without the power.
Authorization Codes activate your Gamry Software to work with your potentiostat. Each of the software packages has a package name (e.g. â€œDC105â€ for DC Corrosion Techniques) and a 10-digit Authorization Code that is linked to the serial number of your instrument.
General instability in the operation of the IC8 can be caused by many things. Instability refers to a loss of keyboard and mouse input, loss of video or a Microsoft BSOD that can only be resolved by restarting the computer. These problems can come about from a corrupted operating system installation or from hardware problems. Operating system problem diagnosis is beyond the scope of this note. All internal power connectors and data cables should be checked for looseness. The most likely culprits for hardware failures that cause instability are: power supply failure or too weak, loose cables to hard drive, power supply or potentiostats, failure of power regulation components on the single board computer (SBC). Detecting a weak or bad power supply is not easy because they must be tested under proper load. If a power supply problem is suspected it is best to contact Gamry Technical Support to discuss the options for replacing the power supply. Failure of power regulation components on the SBC is indicated by bulging or oozing capacitors in the vicinity of the processor.
