Functional Features Supports serial tunnel mode for transparent bidirectional data transmission between serial equipment and Ethernet network. Embedded web server allows full device configuration and status monitoring via web browser. Provides remote firmware upgrade capability without physical disassembly. Supports modem emulation function to replace traditional dial‑up modems. Integrated diagnostic LED indicators display power status, Ethernet link status and serial communication activity. Implements complete network security mechanisms including password access control and encrypted communication channels. DIN‑rail mounting compatible for industrial cabinet installation.
Application Scenarios Oil and gas hazardous area field equipment networking, factory floor legacy PLC and instrument remote access, power station serial monitoring device network conversion, marine automation serial equipment IP transformation, refinery and petrochemical site data acquisition systems, building automation serial controller network interconnection.
Performance Parameters Full‑duplex 100Mbps Ethernet transmission capacity. Zero‑delay transparent serial data forwarding. Maintains stable communication performance under 60 °C maximum rated ambient temperature. Supports multiple concurrent TCP client connections. Hardware‑level surge protection for power and serial ports.
Material Composition Black flame‑retardant ABS industrial plastic enclosure, internal multi‑layer FR‑4 printed circuit board, metal mounting clips for DIN rail installation, gold‑plated RJ45 and terminal block contacts for anti‑oxidation performance.
Structural Features Compact rectangular form factor, side‑mount DIN‑rail buckle structure, front‑facing LED status indicator array, isolated power terminal block, separate serial signal terminals and RJ45 Ethernet port. All connectors locate on the front panel for convenient wiring and visual inspection.
Working Principle The unit receives asynchronous serial data from field serial devices, packages raw serial payload into TCP or UDP Ethernet protocol frames and transmits data to upper‑level network hosts. In reverse direction, Ethernet IP packets are unpacked and converted back into standard serial signal levels for target serial equipment. The on‑board embedded processor executes protocol conversion logic independently without host computer assistance.
Installation Requirements Mount onto standard DIN‑EN 50022 DIN rail inside ventilated industrial control cabinet. Maintain minimum 20 mm clearance around enclosure for heat dissipation. Connect power supply strictly within 9‑30VDC or 9‑24VAC rated range. Use shielded twisted‑pair cable for serial wiring in high‑noise industrial environments. Ground the device chassis to cabinet protective earth ground. Do not install in locations with direct liquid splash exposure.
Usage Notes Verify complete compliance with Class I Div 2 installation standards when deployed in hazardous classified locations. Assign unique static IP address on local area network to avoid IP address conflict. Disable unused network service ports to strengthen network security. Complete power cycle after modification of critical configuration parameters. Avoid operating beyond maximum 60 °C ambient temperature rating. Perform periodic inspection of terminal screw tightening torque to prevent loose connection under equipment vibration.
