Moxa NPort 5630-16, 16xRS422/485, RJ45 10/100M content_copy

The Moxa NPort 5630-16 is an industrial Device-Server with 16 serial ports, specifically designed for integrating RS-422/RS-485 devices into networks. The device is intended for mounting in 19-inch racks and is suitable for applications in industrial automation, communication infrastructure, and other environments where a reliable serial network connection is required. The 8-pin RJ45 ports enable a standardized, robust connection to serial end devices, while the RS-422 and RS-485 interfaces ensure broad compatibility with various industrial devices.

Applications

The NPort 5630-16 is used in environments where serial devices such as sensors, controls, measuring instruments, or industrial peripherals need to be accessed over a network. Support for RS-422 and RS-485 makes it particularly suitable for applications with long transmission distances and high noise immunity. The integrated Ethernet interface enables integration into existing networks, making serial devices accessible over IP networks. This is especially useful in factories, power supply facilities, or public transport, where legacy devices need to be connected to modern network infrastructures.

Functions and Equipment in Detail

The device features 16 serial ports, each connected via 8-pin RJ45 connectors. Baud rates can be set between 50 and 921.600 bps, allowing flexible adaptation to different transmission speeds. Configuration of serial parameters such as data bits (5–8), stop bits (1, 1.5, 2), and parity (none, even, odd, Space, Mark) is performed via the integrated control interface with LCD display and buttons. Flow control supports RTS/CTS, DTR/DSR, and XON/XOFF to prevent data loss. For RS-485 applications, automatic data direction control (ADDC) is integrated, enabling communication without additional control lines. The RS-485 termination resistors are 120 Ω, and the pull-high/low resistors are set to 1 kΩ and 150 kΩ.

Technology Explained Simply

The serial ports of the NPort 5630-16 are implemented via RJ45 connectors, providing a mechanically robust and standardized connection. The RS-422 interface supports bidirectional, full-duplex communication with separate transmit and receive lines (Tx+/-, Rx+/-), while RS-485 enables half-duplex communication, which can be operated in either 2-wire or 4-wire technology. The magnetic isolation of the Ethernet interface at 1.5 kV protects the device from voltage surges and electromagnetic interference. Power supply is via an AC input of 100–240 VAC, ensuring worldwide usability. The integrated watchdog timer ensures automatic recovery in case of a system crash.

Compatibility and Accessories

The NPort 5630-16 supports a wide range of operating systems, including Windows 95 to 11, Server 2003 to 2022, Linux Kernel 2.4.x to 6.x, macOS 10.12–10.15 and 11.x, as well as Android API from 3.1.x. Configuration is performed via Telnet console, web console (HTTP/HTTPS), or a Windows utility software. Network management functions include ARP, BOOTP, DHCP, DNS, ICMP, IPv4, LLDP, RFC2217, Rtelnet, PPP, SLIP, SMTP, SNMPv1/v2c, TCP/IP, Telnet, and UDP. Time synchronization is done via SNTP. Security features include authentication via a local database, encryption using AES-128, RSA-1024, SHA-1, and SHA-256, as well as the use of HTTPS (TLS 1.2) and SNMPv3.

Mounting and Installation

The device is designed for mounting in 19-inch racks and features mounting ears that allow DIN rail mounting. Dimensions are 480 x 45 x 198 mm (with ears) or 440 x 45 x 198 mm (without ears). The enclosure is made of metal, ensuring high mechanical stability and heat dissipation. The control interface with LCD display and buttons enables local configuration and status indication. Installation is performed via the network interface and the serial RJ45 ports, with power supply via the AC input.

Operational Advantages

The NPort 5630-16 offers high reliability with an MTBF of 618,263 hours (according to MIL-HDBK-217F). Electromagnetic compatibility (EMC) complies with standards EN 55032/35, CISPR 32, FCC Part 15B Class A, and IEC 61000-4-2 to -4-11. Safety certification is according to UL 62368-1, and for medical applications, standards EN 55011:2007+A2:2007 Class A and EN 60601-1-2:2007 are met. Operating temperature ranges from 0 to 60 °C, storage temperature from -20 to 70 °C, with humidity between 5 and 95 % (non-condensing). The 5-year warranty underscores the quality and longevity of the device.
