The RTConnect 6-in-1 protocol module is an embedded module that enhances serial devices with universal system compatibility by adding EtherNet/IP, PROFINET, OPC UA, BACnet/IP, Modbus TCP and MQTT. Its compact form factor and dedicated protocol processor makes integration a true drop-in solution. With RTA you get a proven protocol partner, saving you months of development time and engineering overhead with a ready-to-use, market-proven solution.
Key features:
- Add a suite of industrial protocols with a single, compact serial-to-Ethernet interface featuring a proven PHY.
- Accelerate time-to-market by integrating Ethernet into your serial devices with a simple PCB alteration
- Maximize product profitability by replacing costly in-house development with a low-cost module that ensures high margins across your device’s entire lifecycle
- Add wireless communication to send data to the cloud and bridge the gap between the factory floor operations and front office performance indicators
- Minimize development risk with market-proven hardware and software proven in multiple successful device certifications each year
- Get expert support from inception to launch from a protocol partner with over 30+ years of experience
Access any automation market with a versatile protocol module
Enhancing your device with multiple industrial protocols provides a strategic advantage in readying your products for local or international automation markets. Leveraging your existing hardware design, you simply integrate the minimal footprint RTConnect module into your PCB to provide interoperability with Allen-Bradley, Siemens and Schneider Electric PLCs, as well as make your device discoverable in building automation systems.
Best of all, you do not have to write a single line of protocol code. The RTConnect module communicates to the host processor over a serial physical layer and presents the data as your desired ethernet-based protocol. All of the technical complexity and nuance of the six presentation protocols is built into the module. RTA’s white glove service package offloads the complexity of in-house development, providing expert engineer-guided consultation from an RTA Enginerd, data modeling, pre-conformance support and training for your go-to-market efforts.
As your protocol partner, RTA also provides total protocol lifecycle support, handling ongoing protocol maintenance and ensuring your device remains current, competitive and compliant with the latest global standards without requiring device firmware updates.

How does it work?
The RTConnect module does all the heavy lifting to provide you with a suite of industrial protocols:
- Integrate the RTConnect Module footprint into your hardware design
- Supply the RTConnect Module with 3.3V DC and route your existing serial UART
- Follow RTA’s proven development process to define and map your serial data for presentation on EtherNet/IP PROFINET, OPC UA, BACnet/IP, Modbus TCP and MQTT networks
RTA takes care of the groundwork to support your module integration from design to deployment following our proven development process:
- Consult with an Enginerd who provides you with hardware design documentation and collects interface protocol information.
- RTA properly models your device data to each new protocol and provides all documentation.
- RTA conducts internal testing to ensure it meets the highest standards for data integrity and industrial security. For protocols that require certification, RTA also runs certification testing and provides you with the test results you need to present to the conformance lab.
- RTA trains your internal teams and reviews your technical documentation to support your go-to-market efforts.
- RTA handles all protocol maintenance and ensures your custom RTConnect Module is always available to meet production requirements.
