Manually changing the Port number for your ECM8 or TDC4
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.

For a TDC4 Temperature Controller the relevant section of the INI file is:
The PORT=1 setting should be changed to match the newly assigned COM port for the device, whether it is an ECM8 or a TDC4.
