## Long description

The ATEN 1-Port RS-232/422/485 Secure Device Server SN3401P PoE is a compact, industrial-grade solution that enables fast and secure serial-to-Ethernet connectivity for a wide range of serial devices. Supporting RS-232/422/485 interfaces, DC and PoE power sources, and a metal housing with LED indicators for power and status, the SN3401P is designed for reliable remote access and integration of serial equipment into IP networks for commercial and industrial process control environments.
Advantages
The SN3401P provides multi-layered security including network access control, user authentication, and data integrity/confidentiality features. It includes surge and isolation protection (1.5 kV magnetic isolation for Ethernet) and additional surge protection for serial, Ethernet, and power to guard against voltage spikes. The device supports multiple operation modes (Real COM, TCP, Serial Tunneling, Console Management, UDP), functions as a Modbus gateway between Modbus TCP and Modbus RTU/ASCII, and offers 64 KB port buffering, event logging, and automated notifications (SMTP, SNMP Trap) for reliable operation and troubleshooting.
Suitable for
 Industrial process control and SCADA systems
 POS and access control integrations
 Environment and sensor monitoring
 Remote site management and device management

How to use
Install the SN3401P using the appropriate mounting option (wall, desktop, DIN rail, or rack with optional kit). Connect the serial device to the RS-232/422/485 port and attach Ethernet and power (DC or PoE). Access the device setup via the 3-step web console in a browser or via Telnet/SSH for low-bandwidth environments. Configure the desired operation mode (for example Real COM or Modbus gateway), set up network and security parameters, and save the configuration to enable remote access from a PC or networked system.
Usage recommendations
For stable and secure operation, use PoE or a regulated DC power source, enable available security functions (authentication and encrypted channels), maintain firmware updates, and configure event notifications and syslog to monitor device status and capture logs for troubleshooting.
