How to Install Digi Edgeport 1i 1-Port Serial Adapter

Getting started with the Edgeport 1i is straightforward and quick. Follow these general steps to ensure a smooth setup:

• Connect the Edgeport 1i to an available USB port on your computer or server. Use a powered USB hub if you need to expand available ports on a laptop or compact system.
• Power on the host if required; the device is typically bus-powered and will begin enumerating automatically when the USB connection is detected.
• Allow your operating system to recognize the device. In many cases, the system will install a compatible driver automatically. If prompted, install the recommended driver package from the Digi support site or let the OS select a suitable driver.
• Once installation is complete, verify that a new serial port has appeared in your system. On Windows, this will appear as a COM port (e.g., COM3); on macOS or Linux, it will appear as a /dev/tty device. Confirm that the port is ready for configuration in your serial software.
• Connect your RS-232 peripheral to the Edgeport’s serial port and configure your software to use the new COM/tty port. Test communications with a simple loopback or a known-good device to confirm proper operation.
