Key features

• • Serial-to-Wi-Fi TCP/IP conversion for RS232/RS422/RS485 devices (wireless monitoring and control).
• • Wireless RSSI mode helps during installation to validate signal quality and placement.
• • Soft AP allows configuration and connection from mobile devices without a Wi-Fi AP.
• • IPv4/IPv6 dual stack supports long-term networking and transitions to IPv6.
• • WPA-Enterprise security supports enterprise authentication requirements.

Soft AP + RSSI for fast commissioning

CSW-H85K2 is designed for environments where pulling cable is difficult. Soft AP provides a direct setup path from a phone/laptop, while Wireless RSSI helps confirm that the installed location has adequate Wi-Fi signal for stable operation.

• • Configure IP/SSID/security through the web interface for repeatable rollout.
• • Works in typical WLAN topologies (Infrastructure and Ad-hoc) and supports Soft AP for setup.

Communication modes, management & framing

Use standard serial-over-IP modes for remote connectivity, and rely on built-in monitoring tools for commissioning and support. Separator (packet framing) helps when serial traffic is message-based and needs clean packet boundaries.

• • Supports common tunneling modes (TCP Server, TCP Client, UDP) and AT Command mode for flexible setups.
• • Multiple monitoring options: debugging mode, ezManager, and TELNET status checks.
• • Virtual COM (ezVSP) for Windows helps legacy software communicate over Wi-Fi without code changes.
