Serial-to-IP Conversions

At Gridlink IT, we specialize in modernizing legacy infrastructure by converting traditional serial communication protocols (RS-232, RS-485, RS-422) into secure, IP-based transmissions—allowing utilities and energy companies to integrate critical SCADA data, RTUs, and field equipment into modern networks.

OUR BENEFITS

Why Clients Choose GridLink IT

SCADA Integration Over IP Networks

We bridge the gap between legacy serial devices and modern SCADA platforms by converting serial data to TCP/IP using industrial-grade protocol converters and secure network gateways. This enables remote control and monitoring of field devices, IEDs, and RTUs over IP—allowing centralized access, improved visibility, and simplified network management.

RTAC Configuration & Deployment Expertise

Gridlink IT understands and supports leading Real-Time Automation Controller (RTAC) platforms, including SEL RTAC (Schweitzer Engineering Laboratories), NovaTech Orion, GE D20/D400, and ABB RTUs. We provide end-to-end services including serial-to-IP routing, protocol translation (e.g., DNP3, Modbus), and seamless integration into your SCADA master, ensuring deterministic performance and secure control path integrity.

Secure Communications via VPN, MPLS & VPLS

Our solutions include the deployment of site-to-site VPN tunnels, MPLS circuits, and VPLS private networks to securely transport SCADA and RTAC data across wide area networks. We configure robust IPsec encryption, firewall policies, and traffic segmentation to isolate and protect your operational traffic from general-purpose business networks.

Firewall & Network Hardware Expertise

We deploy and manage industrial and utility-grade firewalls and network equipment for secure serial-to-IP transport, including platforms like Fortinet, Palo Alto Networks, Cisco ISR, Cradlepoint, and SEL-3620 security gateways. These systems are configured to support encrypted tunnels, access control lists, port forwarding for serial devices, and monitoring of all traffic endpoints.

Redundant & Fault-Tolerant Network Design

To protect critical SCADA paths, we engineer redundant communication routes with automatic failover across primary and backup tunnels or circuits. Our designs support dual-homed RTUs, redundant firewall pairs, and multiple WAN uplinks to ensure continuous operation of field control systems—even in adverse network conditions.

End-to-End Conversion & Lifecycle Support

From on-site equipment audits and legacy protocol discovery to converter installation, IP configuration, and ongoing monitoring, Gridlink IT delivers full lifecycle support for Serial-to-IP infrastructure. We remain actively engaged through commissioning, testing, and post-deployment, ensuring data integrity, cybersecurity compliance, and long-term operational reliability.

Serial-to-IP Conversions

Secure Modernization of SCADA & RTU Communications

Our Serial-to-IP Conversion services are ideal for linking control houses, substations, and RTACs (Real-Time Automation Controllers) across geographically dispersed assets via secure, reliable, and monitored connections. We work closely with utility providers, solar and wind developers, and EPC contractors to deploy hardened, scalable solutions that meet both operational requirements and cybersecurity standards. Whether you’re managing real-time automation or remote telemetry, we help transition your infrastructure into a flexible, IP-routable architecture without sacrificing control or uptime.
