Series Communication

The "series communication" (more commonly referred to as Serial Communication) market is currently undergoing a significant shift driven by Industrial IoT (IIoT) and the integration of legacy equipment into smart manufacturing ecosystems ContecLapp.

Market Trends & Insights (2026 Outlook)

* Legacy-to-Cloud Integration: The primary market driver is bridging older RS-232/422/485 devices into modern Ethernet and Cloud infrastructures using Modbus TCP and MQTT gateways Rohde-SchwarzCome-Star.

* Edge Intelligence: Communication products are evolving from simple "converters" to intelligent Edge Gateways capable of data processing and protocol conversion at the source SlalomPrnewswire.

* Wireless Expansion: There is a surge in demand for Cellular (4G/5G) and Wi-Fi enabled serial servers to eliminate cabling in harsh industrial environments GsmaintelligenceJuniperresearch.

* Ruggedization: Market requirements are tightening around certifications like CID2 and ATEX for hazardous environments such as oil & gas Advantech.

Product Landscape

The market is divided into three core hardware categories:

1. 1Industrial Gateways: Primarily used for protocol conversion (e.g., Modbus RTU to Modbus TCP) and IoT data acquisition AlibabaAlibaba.
2. 2Serial Device Servers: Provide network connectivity for serial devices, allowing remote control via virtual COM ports AlibabaAlibaba.
3. 3Industrial Converters: Hardened devices for signal conversion (USB to RS485) with galvanic isolation to protect equipment from surges AlibabaAlibaba.
