CSW-H85F – Serial WLAN Device Server
CSW-H85F adds wireless networking to industrial serial equipment via RS232/RS422/RS485, enabling remote monitoring and control over WLAN. It includes Wireless RSSI and Soft AP for convenient field setup, supports IPv4/IPv6 for future-ready deployments, and offers WPA-Enterprise for environments that demand maximum security.
Key features
- • Wireless serial-to-TCP/IP for RS232/RS422/RS485 equipment (remote monitoring & control over WLAN).
- • Wireless RSSI helps with installation and ongoing link quality checks.
- • Soft AP simplifies setup and maintenance without needing an existing Wi-Fi AP.
- • IPv4/IPv6 dual stack supports long-term rollouts and IPv6 migration planning.
- • WPA-Enterprise provides enterprise-grade wireless encryption and authentication.
WLAN modes built for field work
Use CSW-H85F with typical Wi-Fi deployments (Infrastructure and Ad-hoc) and rely on Soft AP when you need fast access during commissioning or maintenance. For secure environments, WPA-Enterprise helps align with enterprise Wi-Fi policies.
- • Configure IP/SSID/security settings via the built-in web interface.
- • RSSI visibility supports better placement decisions and more reliable links.
Communication modes, framing & support tools
CSW-H85F supports standard serial-over-IP tunneling modes and provides tools for monitoring connection status. Separator settings help transport framed serial messages more reliably over TCP/UDP.
- • Supports common tunneling modes (TCP Server, TCP Client, UDP) and AT Command mode for flexible networking.
- • Monitor status via debugging tools, ezManager, and TELNET.
- • Virtual COM (ezVSP) for Windows helps legacy applications connect over Wi-Fi seamlessly.
