Technical Specifications:​ The unit has two DB9 male serial ports configurable for RS-232, RS-422 or RS-485. Ethernet is one RJ45 port with 10/100 Mbit/s auto-negotiation. Serial baud rate is 110–230.4 kbit/s. Per-port buffer is 8 KB. Power input is 9–48 V DC or 8–24 V AC. Current draw is 340 mA at 12 V DC. Operating temperature is -10 °C to 80 °C. Enclosure rating is IP30. Dimensions are 4.46 cm x 15.52 cm x 10.46 cm.

Functional Features:​ The server supports TCP, UDP, HTTP, Telnet, DHCP, ARP, ICMP and virtual COM operation. Heartbeat automatic reconnect restores TCP sessions after power or network loss. Configuration is available through web browser, Telnet, Windows Vlinx Manager or local console.

Performance Parameters:​ Each serial port handles asynchronous data with hardware or software flow control according to the selected interface. The device maintains low-latency store-and-forward conversion between serial clients and Ethernet hosts.

Material Composition:​ The housing uses industrial metal or high-grade plastic depending on the supplied variant. Internal circuits include Ethernet PHY, serial transceivers, ARM or equivalent processor, removable terminal power connector and status LEDs.

Structural Characteristics:​ The compact DIN-rail enclosure provides two DB9 serial connectors, one RJ45 Ethernet connector, removable power terminals, reset and console access, and LEDs for power, link and ready.

Working Principle:​ Serial data from the field device is received, buffered and encapsulated into IP packets. The Ethernet port forwards packets to the host application or virtual COM driver. Return traffic is decoded and transmitted on the assigned serial port.

Installation Requirements:​ Mount on a 35 mm DIN rail inside the control cabinet. Use shielded serial cables for RS-485 multidrop and proper termination for long Ethernet runs. Supply regulated 12–24 V DC through the removable terminal block.

Usage Precautions:​ Match baud rate, data bits, parity and flow control between the server and each serial device. Keep power supply within 9–48 V DC or 8–24 V AC. Update firmware through the web interface and verify network firewall rules before remote access.
