ATEN SN3401 serial server RS-232/422/485

Serial-to-Ethernet Connectivity. 1 RS-232/422/485 serial port for secured serial data over Ethernet transmission. Software-configurable termination (120 Ω) and pull high/low resistor (1K ohms or 150K ohms) integrated to the RS-485 mode to avoid signal reflection. Secured operation modes – Secure Real COM, Secure TCP Server / Client, Secure Serial Tunneling Server / Client,Console Management (SSH), and Console Management Direct (SSH). Standard operation modes – Real COM, TCP Server / Client, Serial Tunneling Server / Client, UDP, Console Management (Telnet), and Console Management Direct (Telnet). Real COM, Real TTY, and Fixed TTY drivers for Windows, Linux, and UNIX. Convenient console management access via Java viewer (SSH / Telnet) or third-party clients such as PuTTY. Easy console port access via Java viewer and Sun Solaris ready (“break-safe”). Multiple users can simultaneously access the same port – up to 16 connections per port. Support Modbus gateway to convert between Modbus TCP and Modbus RTU / ASCII protocols. Hardware. Redundant power input (power jack and terminal block) for fail-safe power. Surge protection for serial, Ethernet, and power. DIN-rail mounting, wall mounting, rack mounting, and desktop installation available. Supports baud rates of 110, 134, 150, 300, 600, 1200, 1800, 2400, 4800, 7200, 9600, 19200, 38400, 57600, 115200, 230.4k, 460.8k, 921.6k bps. Security. Supports secured login from browsers with TLS 1.2 data encryption and RSA 2048-bit certificates. Configurable user permissions for port access and control. Local and remote authentication and login. Third-party authentication (e.g. RADIUS). IP address filter for security protection. System Management. Browser access with an intuitive GUI design. Web-based quick setup wizard for fast configuration. Terminal-based access with a menu-driven UI via Telnet / SSH. Online / Offline detection of connected serial devices (including terminal blocks) – automatically sending event notifications when the devices are offline (e.g. power failure) for device status monitoring. System event logs and port logs will be saved to an internal memory or Syslog server. SNMP agent (v1 / v2c). Event notification – supports notification of SMTP email and SNMP Trap (v1 / v2c). Backup / Restore system configuration and upgradeable firmware. 64 KB port buffer prevents data loss when the network is down. NTP for time server synchronization. Multi-language web-based GUI. An easy-to-use, secure, and reliable solution makes it easier to connect a wide range of serial devices to an IP-based Ethernet LAN in an instant. The ATEN SN3401 Secure Device Server provides simple, fast serial-to-Ethernet connectivity, allowing users to remotely access serial RS-232/422/485 devices from a PC located anywhere. With various reliable features, the SN3401 is ideal for commercial and industrial process control applications. Surge and Isolation Protection Ensure System Stability. Surge protection is a vital aspect of any facility’s coordinated electrical protection to ensure safe and reliable operation. To this end, in addition to 1.5kV magnetic isolation protection for Ethernet signals, the SN3401 Secure Device Server features surge protection for serial, Ethernet, and power that protect against voltage spikes or uncontrolled increase in current. Furthermore, as well as industrial safety standards compliance, they are also tested to meet IEC 61000-4 surge wave form requirements to ensure system stability and reliability. Level-up Device Security at Every Stage. The growing numbers of cyber attacks in the industrial IoT era has the potential to bring down systems and cause huge losses of time and money. In order to avoid potential vulnerability risks, enterprises need a multi-layered defense system to ensure secure data transmissions that include regular firmware upgrades, as well as various encrypted forms of authentication and access control. The SN3401 secure serial-to-Ethernet solution is equipped with security functions at every level, including network access control and user authentication, data integrity and confidentiality. Furthermore, with an operation mode available for advanced security functions, you can acquire any field data needed and provide frontline protection. Comprehensive Secure Operation Modes. The SN3401 offers a broad choice of operation modes to help different types of serial devices to be seen on the network including Real COM, TCP, Serial Tunneling, Console Management and UDP. With each operation mode SN3401 is equipped with advanced secure functions to assist users in streamlining operations and ensuring serial data is securely transmitted. Seamless and Cost-Effective Modbus Gateway. The SN3401 can be used as standard Modbus gateway for conversion between Modbus TCP and Modbus RTU / ASCII protocols. It can integrate Modbus serial slave devices seamlessly into an existing Modbus TCP network, thereby making them accessible to serial master devices....
