Frequently asked questions about the WC505 NAT Coupler
The WC505 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.
WC505 supports 5 IP conventions, allowing mapping of up to five internal subnets to external IPs – ideal for larger production networks with multiple device segments.
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 level 4 protection. Suitable for factory floors and industrial cabinets.
Yes, WC505 supports both Wi‑Fi (2.4GHz, 802.11b/g/n) and Ethernet connections, providing flexible networking options. You can use Wi‑Fi for wireless device segments and Ethernet for backbone connectivity.
Built‑in firewall with SPI, DoS prevention, ACL, and optional VPN (L2TP, PPTP, OpenVPN, IPsec) for secure tunneling.
Yes, the two RS232/485 serial ports support Modbus RTU, making it easy to connect to PLCs, instruments, and other industrial devices.
We offer 1‑year warranty and lifetime technical support. 7×24 hotline, online chat, and remote assistance are available. On‑site deployment services can be arranged.
