The Moxa NPort 5630-8 is an industrial Serial-to-Ethernet device server designed for integrating serial devices into IP-based networks. The device features eight serial RJ45 ports and supports RS-422 and RS-485 standards, making it suitable for demanding environments such as power supply, traffic management, or manufacturing plants. Its construction with a robust metal housing and 19-inch rack mounting enables reliable installation in industrial network infrastructures.

Applications

The NPort 5630-8 is used in environments where serial end devices such as sensors, controls, or measuring instruments need to be accessed via an Ethernet network. Support for RS-422 and RS-485 makes the device particularly suitable for long transmission distances and noise-sensitive environments. The high operating temperature range of -40 to +85 °C and the wide input voltage range of 88 to 300 VDC extend its application scope to extreme climatic and electrical conditions, as found in industry or outdoor installations.

Functions and Equipment in Detail

The device offers eight serial RJ45 connections configured for RS-422 and RS-485. Baud rates can be set between 50 and 921600 bps, including standard rates. Data transmission occurs with 5, 6, 7, or 8 data bits, 1, 1.5, or 2 stop bits, and parity modes None, Even, Odd, Space, or Mark. Flow control is implemented via RTS/CTS, DTR/DSR, or XON/XOFF. For RS-485 applications, a termination resistor of 120 Ohm is provided, with data direction control automatically managed via ADDC. Serial port configuration is performed using DIP switches, which allow setting termination, pull-high, and pull-low.

Technology Explained Simply

The NPort 5630-8 acts as a bridge between serial devices and an Ethernet network. Serial data is converted into IP packets and transmitted over the network. The network interface consists of a 10/100BaseT(X) port with an RJ45 connector and galvanic isolation of 1.5 kV, reducing interference and voltage spikes in the network. Configuration is done via a web browser (HTTP/HTTPS), Telnet, or a Windows utility software. Status indicators via LEDs enable quick diagnosis of network and port conditions.

Compatibility and Accessories

The device is designed for use in industrial networks and supports standard protocols such as TCP, UDP, Telnet, SNMPv1/v2c/v3, HTTPS, IGMP, RFC2217, PPP, SLIP, DHCP, DNS, and LLDP. Configuration via web interface, Telnet, or Windows software enables flexible integration into existing network environments. Compatibility with RS-422 and RS-485 makes it particularly suitable for industrial communication applications.

Mounting and Installation

The NPort 5630-8 is designed for mounting in a 19-inch rack. The robust metal housing provides mechanical protection and heat dissipation. Installation is performed using an included rack mounting kit. Power supply is via a DC input of 88 to 300 VDC, allowing the device to operate from various industrial power sources. Power consumption is 152 mA at 88 VDC.

Operational Advantages

The high operating temperature and wide voltage range increase reliability in harsh environments. Galvanic isolation of the network interface protects against interference. Configuration via web interface, Telnet, or Windows software enables flexible and centralized management. Integrated LEDs simplify diagnosis and maintenance. The MTBF is 506,093 hours (Telcordia TR/SR), indicating a high service life.
