The CN2610-16-2AC from Moxa is a terminal server for industrial applications, offering 16 serial RS-232 interfaces with integrated Dual-LAN functionality and dual AC power supply. The device is designed for use in critical networks where high availability and fault tolerance are required. The redundancy features ensure continuous operation even in the event of a network or power source failure. The two independent Ethernet ports each have their own MAC and IP addresses, enabling flexible network integration. The Redundant COM functionality ensures uninterrupted data transmission over the serial ports, even if one port fails.

Applications
This terminal server is suitable for demanding industrial environments, such as manufacturing automation, power supply, or transportation. It enables the integration of legacy devices with serial interfaces into modern IP-based networks. The robust metal construction and certifications for EMC and safety make it suitable for environments with high electromagnetic interference and strict safety requirements.

Functions and Features in Detail
The device features 16 serial ports in RS-232 standard, connected via 8-pin RJ45 connectors. Operating modes include Real COM, TCP Server/Client, UDP, RFC2217, Terminal, PPP, DRDAS, and Redundant COM. The baud rate can be set between 50 bps and 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 supported via RTS/CTS, DTR/DSR, or XON/XOFF. A console port with RS-232 interface (19200, n, 8, 1) allows local configuration.

Technology Explained Simply
The Dual-LAN function with two 10/100BaseT(X) RJ45 ports provides redundant network connectivity. Each port is equipped with 1.5 kV isolation protection to guard against overvoltage. Network software functions include configuration via Serial Console, Telnet, Windows Utility, DSU, and Web Console (HTTP/HTTPS). Management protocols such as ARP, DHCP, DNS, HTTP, IPv4, SMTP, SNMPv1/2c/3, Telnet, UDP, and ICMP are supported. Routing is handled via RIPV1/V2 and static routes. Security features include HTTPS/SSL, SSH, RADIUS, PAP, CHAP, and encryption with AES-128/256, HMAC, RSA-1024, and SHA-1. Authentication is supported via local database or RADIUS.

Compatibility and Accessories
The CN2610-16-2AC supports a wide range of operating systems, including Windows (95 to 10, Server 2003 to 2019, Embedded CE/XPe), Linux (Kernel 2.4.x to 5.x), UNIX (SCO, QNX, Solaris, FreeBSD, AIX, HP-UX), macOS (up to 10.15), and Android (API from 3.1). Driver support enables easy integration into existing system environments. Serial signals include TxD, RxD, RTS, CTS, DTR, DSR, DCD, and GND. RS-422/RS-485 signals are present but not active for the RS-232 model.

Mounting and Installation
The device is designed for mounting in a 48,3 cm ( 19 inch ) rack and includes mounting ears. Dimensions are 480 x 198 x 45.5 mm (with ears) or 440 x 198 x 45.5 mm (without ears). Weight is 2.640 g. Power supply is via two independent inputs with voltage 100–240 VAC at 50/60 Hz. Power consumption is 130 mA at 110 VAC.

Operational Advantages
The integrated watchdog timer function provides automatic restart in case of failure. Alarm functions such as buzzer and RTC support fault diagnosis. High reliability is demonstrated by an MTBF of 604,346 hours (according to Telcordia TR/SR). Operating temperature ranges from 0 to 55 °C, and humidity from 5 to 95 % (non-condensing). Certifications include EMC (EN 55032/24, CISPR 32, FCC Part 15B Class A), EMS (IEC 61000-4-2 to -4-11), Safety (UL 60950-1), Vibration (IEC 60068-2-6), Drop test (IEC 60068-2-32), and environmental standards (RoHS, CRoHS, WEEE). Warranty is 5 years.

Certifications and Environment
The device complies with EMC Directive EN 55032/24 and is suitable for use in environments with high electromagnetic interference. Safety certification UL 60950-1 ensures safe operation.
