Frequently Asked Questions · Quick Answers

Find answers to common questions about our NAT Couplers.

A NAT Coupler provides network isolation and IP translation between device networks (PLCs, HMIs, CNCs) and application networks (MES, SCADA). It enables unified IP planning, cross-segment access, and prevents IP conflicts and broadcast storms.

WC503/WC703 support 3 IP conventions, while WC505/WC705 support 5 IP conventions. This allows mapping multiple internal subnets to external IPs as needed.

Yes. The NAT Coupler performs IP translation, allowing devices with identical IP addresses in different subnets to coexist and communicate with upper systems without conflict.

Industrial-grade design with wide voltage (9-35V DC), wide temperature (-20°C to 70°C), and EMC protection. Suitable for factory floors and industrial cabinets.

Yes, all models support both Wi-Fi and Ethernet connections, providing flexible networking options. You can use Wi-Fi for wireless device segments and Ethernet for backbone connectivity.
