Description

Digi International EP-USB-4 4-Port RS232 Serial Adapter

Overview

The Digi International EP-USB-4 provides a straightforward method to integrate up to four RS232 serial devices into a system that lacks native serial ports, utilizing a single USB 2.0 connection. This adapter is designed for environments where legacy industrial equipment, laboratory instruments, or specialized peripherals need to communicate with modern computing systems. Its 4-port configuration allows for simultaneous operation, simplifying deployments that require multiple serial interfaces without the need for complex internal card installations. The EP-USB-4 model is a practical solution for extending connectivity for devices that rely on serial communication protocols.

Compatibility

This adapter is compatible with Windows operating systems (XP, Vista, 7, 8, 10, 11) and Linux distributions. It is designed to work with any RS232 serial device that utilizes standard COM port communication. Specific compatibility extends to systems requiring multiple serial ports for data acquisition, device control, or communication with industrial automation hardware. It is not intended for use with RS422 or RS485 devices.

Installation Notes

Installation requires the use of provided drivers, which are available for download. Once drivers are installed, the adapter presents as standard COM ports within the operating system, allowing applications to access the serial devices as if they were directly connected. Ensure sufficient USB power is available; while the adapter itself draws minimal power, connected devices may have their own requirements. For optimal performance and stability, use a direct USB connection to the host computer rather than through unpowered hubs.
