CSW-H85K2 – Serial WLAN Device Server

CSW-H85K2 converts legacy serial devices (RS232/RS422/RS485) into TCP/IP data over Wi-Fi (IEEE 802.11 b/g), enabling remote monitoring and control when wired networking is difficult. It includes Wireless RSSI for easier deployment, Soft AP for setup without an access point, and WPA-Enterprise for high-security environments.

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.

Tools

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.
Wireless RSSI mode
Helps validate signal strength and improves placement decisions during installation.
Soft AP commissioning
Configure and connect directly from a phone/laptop when no access point is available.
Serial interface flexibility
Supports RS232/RS422/RS485 to fit a broad range of industrial serial devices.
WPA-Enterprise security
Enterprise authentication options help meet stricter wireless security policies.
Monitoring & tools
Use ezManager, TELNET, and diagnostics to monitor communication status and maintain uptime.
Separator (packet framing)
Improves transport of framed serial messages across TCP/UDP connections.
