The Moxa CN2610-16 is an industrial terminal server with 16 serial RS-232 ports, designed for integrating serial devices into Ethernet networks. It belongs to the CN2600 series and is particularly suitable for applications requiring high system availability and reliability, such as in power supply, transportation, automation, or infrastructure projects. The device features a Dual-LAN design, providing two independent Ethernet interfaces, each with its own MAC and IP address, enabling automatic switching to the second network in case of failure – a function referred to as Redundant COM. Additionally, a secondary host PC can be connected to continue operation in case of primary system failure. Models with two power supplies (2AC) offer dual power supply redundancy, further increasing fault tolerance.

Applications

The CN2610-16 is designed for industrial environments where high operational reliability and long service life are required. It is suitable for connecting serial devices such as measuring instruments, controls, sensors, or industrial machines to an IP-based network. The broad driver support for various operating systems – including Windows, Linux, Unix systems, macOS, and Android – enables flexible integration into existing IT infrastructures. The devices are designed for critical applications where communication interruption is unacceptable.

Functions and Equipment in Detail

The device offers 16 serial RS-232 interfaces, which can be connected via RJ45 or DB9 connectors (model-dependent). Serial communication supports baud rates from 50 bps to 921.6 kbps, data bits from 5 to 8, stop bits 1, 1.5, or 2, and parity types including None, Even, Odd, Space, and Mark. Flow control mechanisms such as RTS/CTS, DTR/DSR, and XON/XOFF are also integrated. Operating modes include Real COM, TCP Server/Client, UDP, RFC2217, PPP, Reverse Telnet, DRDAS, Terminal, and Redundant COM, allowing flexible adaptation to various application scenarios.

Technology Explained Simply

The Dual-LAN function enables redundant network connectivity, ensuring availability of the serial ports even in case of network failure. The two Ethernet interfaces (10/100BaseT(X) RJ45) are equipped with 1.5 kV magnetic isolation, protecting against interference and voltage spikes. The integrated WDT (Watchdog Timer) and RTC (Real-Time Clock) ensure stable system operation and time synchronization. Security features include authentication via local database or RADIUS, encryption using HTTPS, AES-128/256, HMAC, RSA-1024, and SHA-1, as well as protocols like SSHv2 and SNMPv3 to secure communication.

Compatibility and Accessories

The CN2610-16 supports a wide range of operating systems, including Windows (95 to 10, Server up to 2019), Linux (Kernel 2.4.x to 5.x), various UNIX systems (QNX, SCO, Solaris, AIX, HP-UX), macOS (up to 10.15), and Android (from API 3.1). Network functions include protocols such as TCP/IP, UDP, Telnet, SNMPv1/2c/3, HTTP/S, RADIUS, SSH, DNS, DHCP, BOOTP, as well as routing via RIPV1/V2 and static routes. Management is performed via Telnet, Serial Console, Windows Utility, or a web console (model-dependent). The devices are equipped with certifications according to EMC (CISPR 32, FCC Part 15B, IEC 61000-4-x), safety (UL 60950-1 / UL 62368-1, model-dependent), and environmental standards.

Mounting and Installation

The device features a metal housing and is designed for mounting in a 48,3 cm ( 19 inch ) rack. Dimensions are 480 x 198 x 45.5 mm (with mounting ears). Operating temperature for standard models is 0 to 55 °C, for T-models -40 to 85 °C. Storage temperature is -40 to 85 °C, and humidity is 5 % to 95 % (non-condensing). Operating voltage is 100–240 VAC for AC models and 88–300 VDC for HV models. The number of power supplies is 1 by default, 2 for 2AC models.

Operational Advantages

High reliability is underscored by an MTBF of up to 831,925 hours. The robust construction, broad compatibility, and integrated redundancy functions ensure high system availability. Easy installation and maintenance via the rack mounting kit and quick start guide facilitate use in industrial environments. Integrated security and support for many network protocols make the device a scalable solution for serial network communication.

Scope of Delivery

The device is delivered with an RJ45-to-DB9 console cable, one or two network cables (depending on model), a rack mounting kit, a quick start guide, and a warranty card.

Certifications and Standards

The devices comply with EMC requirements according to CISPR 32, FCC Part 15B, and IEC 61000-4-x. Safety certifications include UL 60950-1 and UL 62368-1 (model-dependent). Operating temperature ranges and humidity are designed for use in industrial environments. The devices are suitable for outdoor use if environmental conditions remain within specified limits.
