1-Port RS-232/422/485 Secure Serial Device Server with PoE
SN3401P
Device server networking one RS-232/422/485 serial port over Ethernet with secured operation modes; powered by PoE (IEEE 802.3af), DC jack or terminal block.
Features
- 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
- Redundant power input (power jack and terminal block) for fail-safe power
- IEEE 802.3af-compliant PoE PD (powered device) equipment
- 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

- IP address filter for security protection
- 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
