The NPort 5610-8-48V from Moxa is a Device-Server for integrating serial devices into an Ethernet network. It enables the connection of up to eight serial end devices via RS-232 interfaces to a local or higher-level network. The device is specifically designed for applications such as industrial automation, power supply, traffic control systems, or server rooms, where reliable and robust communication between legacy hardware and modern network infrastructures is required. The 19-inch rackmount design ensures easy integration into existing IT systems and allows standardized mounting in server racks.

Applications
The NPort 5610-8-48V is suitable for applications where serial devices such as sensors, controls, printers, or industrial machines need to be accessed over a network. The connection is made via Ethernet (RJ45) with a data rate of 10/100BaseT(X), while galvanic isolation of 1.5 kV increases immunity to interference. The serial ports are implemented as 8-pin RJ45 sockets, enabling standardized and robust cabling. The RS-232 interface supports baud rates from 50 to 921.6 kbps, allowing flexible adaptation to different devices.

Functions and Equipment in Detail
The device offers various serial operating modes, including Real COM, TTY, TCP Server/Client, UDP, Reverse Telnet, Pair Connection, RFC2217, and Ethernet Modem. These modes enable flexible communication, depending on whether the serial devices should appear as COM ports in the operating system or be accessed via network protocols. Flow control can be managed via RTS/CTS, DTR/DSR, or XON/XOFF, stabilizing data transmission. The configurable LCD display (on standard models) supports local IP address assignment and status indication, simplifying on-site configuration.

Technology Explained Simply
Power supply is via ±48 VDC (within the range of 20–72 VDC), enabling flexible use in industrial environments with existing DC networks. Power consumption varies by model, ranging from approximately 135 to 174 mA. The housing is made of metal and provides high mechanical protection. The operating temperature is 0 to 60 °C, suitable for use in controlled indoor environments. Humidity may range from 5–95 % (non-condensing). Certifications include EMC standards such as EN 55032/35 and FCC Part 15B Class A, as well as safety standards such as UL 62368-1. For medical applications, selected models are certified to EN 60601-1-2. Green Compliance includes RoHS and WEEE, ensuring environmental compatibility.

Compatibility and Accessories
The NPort 5610-8-48V is compatible with various operating systems, as drivers are available for common systems. Support for SNMP enables monitoring and management of the device via network management systems. Optionally, a fiber optic connection (100BaseFX SC) can be used, increasing range and interference immunity. The serial ports are designed for RS-232, ensuring compatibility with devices supporting this interface.

Mounting and Installation
Mounting is done using a rack mounting kit, included in the delivery. The device is inserted into a 19-inch rack and secured with mounting ears. Dimensions are 440 × 45 × 198 mm (without ears) or 480 × 45 × 198 mm (with ears). Installation is simple, as the serial ports feature RJ45 sockets that can be connected with standard cables. Configuration is performed via the LCD display and buttons or using network tools.

Advantages in Operation
The NPort 5610-8-48V offers high operational reliability through galvanic isolation, robust construction, and high MTBF (up to 903,009 hours). Rack mounting and Ethernet integration simplify integration into existing networks. Support for various serial operating modes and flow control methods increases flexibility when communicating with different devices. The DC power supply enables use in environments where AC mains voltage is not available.
