ATEN 1-Port RS-232/422/485 Secure Device Server SN3401


The SN3401 Secure Device Server is external IP-based network device that securely connects legacy RS-232/422/485 serial devices to an Ethernet network to be accessed remotely from a computer located anywhere, allowing users to expand the number of serial ports for any host computer over a network.

  • 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
