1-Port RS-232/422/485 Secure Device Server with PoE

New
SN3401P
MSRP: Quote Upon Request
  • 1 RS-232/422/485 serial port for secured serial data over Ethernet transmission
  • Secured operation modes – Secure Real COM, Secure TCP Server / Client, Secure Serial Tunneling Server / Client, Console Management (SSH), and Console Management Direct (SSH)
  • Redundant power input (power jack and terminal block) for fail-safe power; IEEE 802.3af-compliant PoE PD (powered device) equipment
  • Support Modbus gateway to convert between Modbus TCP and Modbus RTU / ASCII protocols

The SN3401P 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.

The SN3401P is especially suited for industrial process control applications, given the abundant use of the Supervisory Control and Data Acquisition (SCADA) systems across many industries for collecting data from PLCs, meters, and sensors via serial ports. The SN3401P bi-directionally translates data between serial and Ethernet formats, and facilitates access to the data from all data collection instruments from local and remote sites through an Ethernet network.

The SN3401P has a number of useful operation modes. It supports secure TCP server / client, secure serial tunneling server / client, secure Real COM, and console management modes for security-critical applications, such as telecom, access control, and remote site management. Furthermore, its IEEE 802.3af-compliant models can be powered by a PoE PSE device without an additional power supply.

The SN3401P can be used as standard Modbus gateway to convert between Modbus TCP and Modbus RTU / ASCII protocols. It can integrate Modbus serial slave devices seamlessly into an existing Modbus TCP network and thereby make them accessible to serial master devices.
