Key features

• • Industrial operating temperature range: -40°C to +85°C for demanding installations.
• • IPv4/IPv6 dual stack with IPv6 auto-configuration support (DHCPv6, stateful/stateless).
• • Flexible serial tunneling: connect serial devices over LAN/Internet without rewriting your legacy system.
• • Virtual COM port driver (ezVSP): use your serial device as if it were locally connected to your PC.
• • Strong security options: SSL + IP/MAC filtering and password-protected configuration access.
• • Packet fragmentation separator settings for cleaner, more reliable serial-to-network data framing.

Remote serial networking (LAN / Internet)

CSE-H53N bridges RS-232 equipment to TCP/IP networks so you can monitor, control, and integrate serial devices remotely. It’s a practical choice for system integrators who need fast Ethernet connectivity for existing machines—without redesigning the whole system.

• • Typical use cases include remote console monitoring, PLC control over IP, and serial equipment access across sites.
• • Built-in network services such as DNS / DDNS help keep devices reachable even when IP addresses change.
• • Monitor status via ezManager and TELNET for quick diagnostics during commissioning and service.

Flexible communication modes (TCP / UDP / AT command)

Choose the operating mode that fits your integration: TCP Server for passive connections, TCP Client for active outbound connections, UDP for lightweight block-based communication, or AT Command mode for modem-style control of sessions.

• • TCP Server / TCP Client for stable serial tunneling and long-lived connections.
• • UDP mode for block-based transmission (useful where connection overhead must be minimal).
• • TELNET COM Port Control Option (RFC 2217) for remote serial port control features in supported software.

Security & multi-monitoring

Protect remote access to your serial infrastructure with SSL and host restrictions. For monitoring scenarios, CSE-H53N can support multiple sessions so several tools or operators can observe device data in parallel (firmware dependent).

• • SSL (Secure Socket Layer) for encrypted TCP communications.
• • IP & MAC filtering to restrict access to trusted hosts or networks.
• • Multiple connection feature for parallel monitoring (up to 8 sessions, firmware dependent).
