Step-by-step Instructions for Changing Your ECM8 COM Port Number

 

Gamry ecm8

NOTE: Be sure to install the drivers for the USB-to-Serial Converter before beginning. The drivers can be found on a CD supplied with the converter

 A Note about USB to Serial Converters. Always use the same physical USB port for your ECM8:

Windows initializes the USB converter device and automatically assigns the next available COM port. This is a problem if the converter is plugged into a different physical USB port, as windows will see it as a brand new device and will initialize it with a new COM port number. The ECM8 is not plug and play, and thus the software has no knowledge of the settings change. This will not be a problem if the same physical USB port is always used.
