The Moxa CN2610-8-2AC is an industrial terminal server designed specifically for use in critical application areas such as automation technology, power supply, and infrastructure. The device features eight serial RS-232 interfaces and enables the integration of legacy devices into modern networks. By combining two independent LAN ports and two AC power inputs, it ensures uninterrupted communication, even in the event of a network or power failure. The two LAN ports operate with separate MAC and IP addresses, enabling redundant network connectivity. Power supply is provided via two inputs with a voltage of 100 to 240 VAC, enhancing operational reliability.

Applications

The terminal server is designed for industrial environments where high availability and stability of communication are required. It is suitable, for example, for connecting machines, sensors, controls, or measuring devices to an Ethernet network. Support for protocols such as TCP/IP, UDP, and RFC2217 makes it flexible for use in various network architectures. Broad driver support for operating systems including Windows, Linux, UNIX, macOS, and Android facilitates integration into existing IT infrastructures.

Functions and Features in Detail

The device offers eight serial RS-232 ports connected via an 8-pin RJ45 connector. The serial interfaces support various operating modes, including Real COM, TCP Server/Client, UDP, Terminal, Reverse Telnet, PPP, DRDAS, and Redundant COM. The baud rate can be set between 50 bps and 921.6 kbps, with configurable data bits (5, 6, 7, 8), stop bits (1, 1.5, 2), and parity types (None, Even, Odd, Space, Mark). Flow control options include RTS/CTS, DTR/DSR, XON/XOFF, and None. An integrated watchdog timer ensures system stability, and alarm functions such as a buzzer and RTC (Real-Time Clock) support fault diagnosis.

Technology Explained Simply

The two Ethernet interfaces operate at 10/100BaseT(X) and are available via RJ45 connectors. They are equipped with magnetic isolation of 1.5 kV, ensuring high immunity to interference. Network software functions include management protocols such as ARP, BOOTP, DHCP, DNS, SNMPv1/v2c/v3, Telnet, UDP, TCP/IP, ICMP, SLIP, and SMTP. Routing functions such as RIPV1/V2 and static routes allow flexible network configuration. Configuration can be performed via various methods: Serial Console, Telnet, Windows Utility, DSU, or a web interface (HTTP/HTTPS). Security functions include HTTPS, SSL, SSH, PAP, CHAP, and RADIUS to protect access to the device.

Compatibility and Accessories

The terminal server is compatible with a wide range of operating systems. For Windows, versions from 95 to 10 as well as Server 2003 to 2019 (x86/x64) are supported. Additional systems include Windows Embedded CE 5.0/6.0, XP Embedded, Linux (Kernel 2.4.x to 5.x), UNIX (SCO, QNX, Solaris, AIX, HP-UX), macOS (up to version 10.15), and Android (from version 3.1). The serial signals include TxD, RxD, RTS, CTS, DTR, DSR, DCD, and GND. RS-422/485 signals are present but deactivated in this model.

Mounting and Installation

The device is designed for mounting in a 19-inch rack. The robust metal housing provides mechanical protection and is designed for industrial environments. Dimensions are 480 x 198 x 45.5 mm (with mounting ears) or 440 x 198 x 45.5 mm (without ears). Weight is 2,560 g. Mounting is done via integrated rack ears, enabling secure fixation in the rack.

Operational Advantages

High reliability is underscored by an MTBF of 773,268 hours (according to Telcordia TR/SR). The device complies with EMC and safety standards such as EN 55032/24, CISPR 32, FCC Part 15B Class A, IEC 61000-4-2 to -4-11, and UL 60950-1. It is also certified for vibration tests (IEC 60068-2-6) and drop tests (IEC 60068-2-32). Environmental conditions include an operating temperature of 0 to 55 °C and humidity of 5 to 95 % (non-condensing). Warranty is 5 years.

Certifications and Environmental Standards

The device complies with environmental standards RoHS, CRoHS, and WEEE. Certifications include EMC, EMI, EMS, safety, vibration, and drop test, confirming suitability for demanding industrial applications. Integrated security functions such as HTTPS, SSH, and RADIUS protect against unauthorized access and support use in safety-critical environments.
