Moxa serial converters are devices that convert serial communication (RS-232, RS-485, RS-422) to other protocols like Ethernet (TCP/IP), fiber optic, or USB. These converters allow legacy serial devices to interface with modern networked systems, enabling communication in industrial and commercial environments where integration with newer technologies is required. Moxa offers a variety of serial converters, each designed to meet different communication needs. Below are the key types, features, and examples of Moxa serial converters: 1. Types of Moxa Serial Converters: Serial-to-Ethernet Converters: These devices convert serial communication protocols (RS-232, RS-485, RS-422) into Ethernet protocols (TCP/IP), allowing serial devices to communicate over an IP network. Serial-to-Fiber Converters: These converters transform serial signals to fiber optic communication, enabling long-distance communication and isolation from electromagnetic interference. RS-232 to RS-485/RS-422 Converters: These devices enable the conversion between different serial protocols, such as RS-232 to RS-485 or RS-232 to RS-422. USB to Serial Converters: These converters allow serial devices to be connected to a USB port on a computer, often used for connecting legacy devices to modern computers. RS-485/RS-422 to RS-232 Converters: Convert RS-485 or RS-422 signals to the more common RS-232 signals, typically used to adapt systems that use different serial standards. 2. Key Features: Wide Voltage Range: Moxa serial converters often support wide input voltage ranges (e.g., 12-48V DC) for flexible power sourcing, making them ideal for industrial settings. Industrial-Grade Design: Many models are designed for harsh environments, with features like DIN-rail mounting, wide temperature ranges, and surge protection to ensure reliability. Plug-and-Play Operation: Easy to install and configure, making them ideal for quick deployment in various applications. RS-232, RS-485, RS-422 Support: They typically support multiple serial communication standards for versatile use cases. Auto Baud Rate Detection: Many converters automatically detect and adjust to the baud rate of the connected devices. Isolation: Some converters offer optical isolation or galvanic isolation to protect connected equipment from electrical surges, noise, or faults in the communication lines. Redundant Power Inputs: For higher reliability, some Moxa converters come with dual power inputs, ensuring continued operation even in the event of power failure on one input. 3. Popular Moxa Serial Converter Models: Moxa NPort Series (Serial to Ethernet Converters): NPort 5100 Series: Converts serial communication (RS-232, RS-485) to Ethernet (TCP/IP). These models are often used in industrial settings to integrate legacy serial devices (like PLCs, sensors, and meters) into Ethernet networks. NPort 5110: A single-port serial-to-Ethernet converter, typically used for simple RS-232-to-Ethernet conversion. NPort 5150A: A 1-port RS-232/485/422 to Ethernet converter. Compact and designed for integration with industrial control systems and automation equipment. NPort 5200 Series: A multi-port version for connecting multiple serial devices to an Ethernet network. Often used in SCADA systems, factory automation, and remote monitoring applications. Moxa MiiNePort Series (Embedded Serial-to-Ethernet Converters): MiiNePort E1: An embedded device server with a single serial port, designed for integration into products that require serial-to-Ethernet conversion. OEMs and industrial equipment manufacturers use this for adding Ethernet capability to their devices. MiiNePort E2: This version offers two serial ports, designed for applications where more than one serial device needs to be integrated into a networked system. Moxa UPort Series (USB-to-Serial Converters): UPort 1000 Series: Offers a simple USB-to-RS-232/RS-485/RS-422 conversion, typically used for connecting legacy serial devices to modern computers with USB ports. UPort 2000 Series: A multi-port USB-to-serial converter, often used for connecting multiple serial devices via a single USB port on a computer or industrial PC. Moxa NPort IAW Series (Industrial-Grade Serial-to-Ethernet Converters): NPort IAW5000A Series: Designed for use in industrial environments. These converters feature advanced surge protection and a wide temperature range, providing a highly durable and reliable solution for harsh conditions. NPort IAW5410A: A model designed for Modbus TCP to Modbus RTU gateway conversion, ideal for integrating Modbus-based serial devices with Ethernet networks. 4. Applications: Industrial Automation: Connecting legacy serial devices (e.g., PLCs, HMIs) to modern industrial networks (Ethernet or fiber optic). SCADA Systems: Integrating remote serial devices into SCADA systems for real-time data acquisition and control.
