Digi Edgeport/1 USB-to-Serial Adapter

The Edgeport/1 USB-to-serial converter is the newest member of the Edgeport family of enterprise Universal Serial Port (USB) connectivity solutions. Designed for reliability in demanding environments, this ultra-compact, single-port module delivers the same proven performance and durable operation as its larger siblings, only in a footprint that’s one-sixth the size of the Edgeport/2. Ideal for tight spaces, field deployments, and cluttered lab benches, the Edgeport/1 makes it effortless to retrofit legacy RS-232 equipment to modern USB systems without sacrificing speed or stability. It’s the smart, scalable choice for engineers and technicians who depend on robust serial communication to control instruments, gateways, test benches and point-of-sale peripherals.

• Compact, field-ready design: One-port Edgeport module that fits where other adapters won’t. Its tiny form factor reduces cable clutter and enables easy integration into cramped enclosures, equipment racks, or portable rigs while maintaining the rugged reliability you expect from the Edgeport line.
• High-reliability RS-232 serial interface: Delivers dependable, industry-standard serial communications with standard RS-232 electrical levels, supporting common handshaking lines and a wide range of baud rates. The Edgeport/1 preserves signal integrity in industrial environments, ensuring stable data transfer for critical instrumentation and automation tasks.
• Plug-and-play with broad OS support: Recognized as a USB-to-serial device across Windows, macOS and Linux environments. With Digi-provided drivers, it appears as a COM port to terminal programs, lab software, and device managers, simplifying integration with existing software stacks and automation pipelines.
• Enterprise-grade performance for legacy devices: Designed to bridge legacy serial devices to modern USB hosts without sacrificing throughput or reliability. It’s perfect for data logging, test benches, embedded development, point-of-sale peripherals, network equipment consoles, and industrial controllers that still rely on RS-232.
• Low power, simple deployment: Bus-powered from USB, requiring no external power supply. The Edgeport/1 minimizes cabling, reduces power budget concerns, and supports quick, hot-plug installation—ideal for rapid field deployments and maintenance routines.

How to install Edgeport/1 USB-to-Serial Adapter

• Connect the Edgeport/1 to an available USB port on your computer or embedded system. The device is bus-powered and does not require an external power supply.
• Install the appropriate Digi USB-to-Serial drivers on your operating system. Windows, macOS, and Linux platforms typically require a dedicated driver package from Digi to ensure the device is recognized as a virtual COM port.
• After installation, verify that the new serial port appears in your system’s device manager or equivalent interface. On Windows, this will appear under Ports (COM & LPT) as a new COM port (e.g., COM3). On Linux, check dmesg and /dev for a new ttyUSB* device. On macOS, you may see /dev/tty.usbserial or similar entries.
• Configure your serial communication software with the correct COM/tty device, baud rate, data bits, parity, and stop bits according to your peripheral’s requirements. The Edgeport/1 supports the standard RS-232 protocol, so most legacy devices can be configured with familiar settings.
• Test the connection with a simple terminal program or test utility to confirm data flow in both directions. If you encounter issues, verify cable integrity, handshaking lines, and whether the target device requires flow control (RTS/CTS or DTR/DSR) to operate.

Frequently asked questions

• Q: What is the Edgeport/1 USB-to-Serial Adapter? A: It is a single-port USB-to-serial converter in the Edgeport family, designed to connect RS-232 serial devices to USB hosts with enterprise-grade reliability and a compact footprint.
• Q: Which operating systems are supported? A: Edgeport/1 supports Windows, macOS, and Linux with the appropriate Digi drivers. It is also compatible with virtualized environments that expose USB devices to guest systems.
• Q: Do I need an external power supply? A: No. The Edgeport/1 is bus-powered from the USB port, making setup and deployment simple and cable-friendly.
• Q: What kind of devices can I connect? A: Any RS-232 serial device that uses a DB9 interface, including data loggers, lab instruments, network equipment consoles, CNC machines, industrial controllers, and POS peripherals.
• Q: How do I know which COM port to use? A: After installing the drivers, the new RS-232 port will appear as a COM port on Windows (e.g., COM3) or a tty device on Linux/macOS. Use your software’s serial port settings to match the device’s requirements.
• Q: Can this adapter work with USB hubs or docking stations? A: Yes. It supports typical USB hub configurations, but for best reliability, connect directly to a powered USB port when possible and verify performance with the connected serial device.
