Connect Legacy Serial Equipment to Modern Networks with Antaira's STE-6104C-T-V2 Industrial Gateway

­For operators looking to modernize without replacing proven equipment, Antaira Technologies highlights the STE-6104C-T-V2, a 4-port industrial gateway that connects virtually any RS-232, RS-422 or RS-485 serial device to a new or existing Ethernet (TCP/IP) network. With redundant Ethernet, wide-temperature operation and a 5-year warranty, it gives engineers a dependable path from the field device to the control room.

Bridging Serial and Ethernet

Factories, substations, water plants and transit systems still rely on serial equipment: PLCs, CNC machines, meters, scanners, scales and RTUs. These devices are reliable and costly to replace, but their serial ports were built for point-to-point cabling, not networked operations.

The STE-6104C-T-V2 closes that gap. It converts each device's serial data into standard TCP/IP traffic and back, so SCADA, HMIs, historians and control software can reach the device from anywhere on the network. No rewiring, no firmware changes, no replacement — just legacy equipment with a modern network presence and data ready for monitoring, analytics and IIoT.

Proven in Real-World Applications

• Factory automation: Connect PLCs, CNC controllers and barcode readers to MES and SCADA for live visibility into machine status.
• Power and utilities: Link RS-485 power meters, relays and RTUs to central monitoring and eliminate truck rolls for routine data collection.
• Water, oil and gas: Bring flow meters, pump controllers and analyzers at remote stations online for around-the-clock monitoring.
• Transportation and buildings: Network message signs, HVAC, access-control and fire panels into one management platform.

Engineered for Uptime and Harsh Environments

• Redundancy built in. Dual 10/100 Mbps Fast Ethernet ports keep critical devices communicating if one link or switch fails.
• Fast, flexible serial. Four RS-232/422/485 ports run at up to 921 Kbps, with 15KV ESD protection on every serial line.
• Fits any architecture. RAW TCP Server, TCP Client, UDP, Virtual COM and Tunneling modes support everything from SCADA integration to running existing Windows software unchanged over the network, or replacing long serial cable runs with Ethernet.
• Easy to manage. A built-in web server, serial console, Telnet and a Windows-based utility simplify setup and troubleshooting, on site or remote.
• Industrial-grade. A rigid IP30 metal housing, DIN-rail or wall mounting, and -40°C to 85°C operation let it go wherever the equipment is.

The Bottom Line

The STE-6104C-T-V2 helps operators protect existing equipment investments, cut downtime and site visits, simplify cabling and unlock serial device data, all on hardware built to last and backed by a 5-year warranty.
