The Device-Server NPort 5610-16-48V from Moxa is designed for connecting up to 16 serial devices over an Ethernet network. It is specifically designed for use in industrial environments as well as data centres, where reliable and maintenance-friendly integration of legacy devices into modern networks is required. The device enables the transmission of serial data (RS-232) over IP-based networks, eliminating the need for physical cable connections and enabling remote control and monitoring of devices over long distances. The 19-inch rack mounting solution makes it ideal for use in server and network enclosures.

Applications

The NPort 5610-16-48V is suitable for applications in the industrial sector where serial devices such as sensors, controls, printers or measuring instruments need to be integrated into an Ethernet network. It is particularly suited for environments requiring high availability and long operating life, such as production facilities, power supply networks or building automation. The support for RS-232 interfaces makes it especially suitable for older devices that are still in use.

Functions and Equipment in Detail

The device features 16 serial ports, each connected via an 8-pin RJ45 connector. The serial interfaces support a baud rate of 50 to 921.6 kbps, with configurable data bits (5–8), stop bits (1, 1.5, 2) and parity types (none, even, odd, Space, Mark). Flow control is achieved via RTS/CTS, DTR/DSR or XON/XOFF. LED indicators are available for configuration and monitoring, displaying the status of the serial ports and the network connection. Standard models include an LCD screen and buttons to perform IP configuration on-site – particularly useful during commissioning at remote locations.

Technology Explained Simply

The NPort 5610-16-48V operates as a Device-Server, converting serial data into IP packets and transmitting them over an Ethernet network. This enables communication between serial devices and computers or servers equipped with TCP/IP. The integrated isolation of 1.5 kV between the Ethernet and serial interfaces protects the device and connected equipment from voltage surges. Power supply is via ±48 VDC, making it suitable for use in telecommunications or security systems where such voltages are standard. Power consumption is approximately 135–174 mA at 100 VAC, with exact values depending on the model.

Compatibility and Accessories

The device supports various operating modes, including Real COM, TTY, TCP Server/Client, UDP, Ethernet Modem, RFC2217, Reverse Telnet and Pair Connection. This flexibility enables integration into different network environments and operating systems. Serial drivers for various operating systems are available to ensure reliable communication with connected devices. Optionally, a fibre optic connection (100BaseFX, SC, single-/multi-mode) can be used to increase network range and minimise electromagnetic interference.

Mounting and Installation

The NPort 5610-16-48V is designed for installation in 19-inch racks. Mounting is done using an included rack mounting kit, ensuring secure fixation in the enclosure. Physical dimensions are 440/480 × 45 × 198 mm, with exact length varying by model. The housing is made of metal, ensuring high mechanical stability and heat dissipation. Installation is performed via the integrated web interface, Telnet or a Windows tool, enabling remote configuration.

Operational Advantages

The NPort 5610-16-48V offers high operational reliability with an MTBF of up to 903,000 hours, making it suitable for critical applications. Support for a wide voltage range (±48 VDC) and high EMC immunity (up to 15 kV ESD) increases reliability in demanding environments. The integrated isolation and EMC compliance according to CISPR 32 and FCC Part 15B Class A ensure stable network connection even in electrically noisy environments. Safety certification according to UL 62368-1 and partial compliance with EN 60601-1-2 (medical devices) extend its application range to sensitive use cases.

Scope of Delivery

The device is delivered with a network cable (for AC versions), a rack mounting kit, a Quick Installation Guide and a warranty card. The listed components are sufficient for installation and commissioning.

Operating Environment

Operation is within a temperature range of 0 to 60 °C (standard model). Humidity may range from 5 to 95 % r.H. (non-condensing). For special applications, models with an extended temperature range (up to -85 °C) are available, although not for this model.

Safety and EMC

The device meets EMI requirements (CISPR 32, FCC Part 15B Class A) and EMS requirements (IEC 61000-4-x, up to 15 kV ESD). Safety certification according to UL 62368-1 ensures suitability for commercial and industrial environments. Partial compliance with EN 60601-1-2 makes it suitable for use in medical applications, provided specific requirements are met.
