WIZ100SR Übersicht
A Serial-to-Ethernet (also called RS232-to-Ethernet) module is a small embedded network appliance that transparently bridges a legacy asynchronous serial port to a TCP/IP network so that older equipment without native Ethernet can be monitored, controlled, or upgraded over LAN/WAN. In the wider product taxonomy the WIZ100SR sits within Interface Modules > Communication Modules > Serial Converters > Ethernet Bridges > IoT Connectivity Modules > Embedded Networking Modules, where it belongs to the same family as the WIZ105SR (RS-485 variant), WIZ120SR, WIZ145SR, and the newer W7500-based WIZ750SR-100 series.
Key features include transparent serial tunneling in TCP Server, TCP Client, and UDP modes, configurable via the WIZnet Configuration Tool over Ethernet or RS-232, plus status LEDs for link, activity, and serial traffic. The integrated W5100 silicon provides 16 KB of dedicated TX/RX buffer memory per socket, eliminating the need for an external TCP/IP software stack and freeing the host 8051 MCU for application-layer processing.
Typical applications include industrial RS-232 device networking (CNC controllers, weighing scales, PLCs, access controllers), remote serial port sharing over LAN/WAN, building-automation gateways, and point-of-sale (POS) terminal retrofits. The WIZ100SR is also widely used to add Ethernet connectivity to legacy instrumentation that lacks an embedded network stack.
Design considerations include providing adequate 3.3 V decoupling near the module pins and reserving space for the RJ45 magnetics footprint. Compared with the newer WIZ750SR-100, the WIZ100SR is a cost-effective legacy platform, but the W7500-based successor offers a Cortex-M0 core, an IP101GRI PHY, and improved software compatibility for green-field designs.

Industrial RS-232 Device Networking
The WIZ100SR's RS-232 serial-to-Ethernet bridging makes it ideal for networking legacy industrial equipment that lacks native Ethernet. With its integrated W5100 silicon handling TCP, UDP, ARP, ICMP, IPv4, IGMP, and PPPoE entirely in hardware, the module can connect PLCs, CNC machines, and access controllers to a LAN/WAN with transparent serial tunneling in TCP Server, TCP Client, or UDP modes. Operating from a 3.3 V supply across the 0 °C to +80 °C commercial range, the WIZ100SR attaches to existing RS-232 ports without requiring any firmware changes on the host device. Compared to swapping out a working PLC, designers can drop in the WIZ100SR to add remote monitoring while preserving the proven 8051 host platform. Recommended companion MPNs: W5100, W5500, MAX3232.

Remote Serial Port Sharing over LAN
The WIZ100SR enables shared remote access to a single RS-232 device by multiple networked hosts, fitting building-automation and lab-instrumentation use cases. Its 16 KB per-socket buffer on the W5100 silicon provides headroom for variable serial speeds up to 115200 bps while preventing TCP back-pressure stalls, while the configurable local and remote TCP ports make integration with virtual COM-port utilities straightforward. Designers typically deploy the WIZ100SR in TCP Server mode at a fixed port, then route the inbound Ethernet traffic through firewall ACLs. Compared with a USB-to-Ethernet adapter, the WIZ100SR operates independently of any host PC and tolerates industrial temperature swings inside a control cabinet.
Empfohlen
Building-Automation Gateways
The WIZ100SR bridges BACnet/Modbus-friendly RS-232 devices into IP networks, enabling HVAC controllers, access-control panels, and energy meters to report over standard LAN cabling. With a 3.3 V single-supply rail and 0 °C to +80 °C commercial operating range, it fits concealed electrical panels and rooftop equipment enclosures without additional power conditioning. The WIZ100SR's broadcast-searchable WIZnet Configuration Tool simplifies bulk deployment across many building-automation gateways by allowing all units to be configured from a single laptop. Compared with newer W7500-based successors, the WIZ100SR remains a proven long-life platform with documented field history in commercial-building deployments.
Empfohlen
POS Terminal Ethernet Retrofit
The WIZ100SR brings Ethernet connectivity to legacy point-of-sale terminals that expose only RS-232 receipt-printer or barcode-scanner ports, eliminating the need for full hardware replacement. Its transparent TCP Server mode lets a central POS server poll each terminal over the LAN, while UDP mode supports broadcast inventory queries. The on-module W5100 silicon delivers reliable TCP retransmission without host-side firmware changes, and the integrated RJ45 with magnetics removes the need for an external Ethernet transformer. Operating at 3.3 V with a compact through-hole footprint, the WIZ100SR fits inside most existing POS chassis without mechanical rework.
Empfohlen
Test and Measurement Instrument Networking
The WIZ100SR's RS-232 to TCP/IP bridging makes bench instruments such as oscilloscopes, spectrum analyzers, and power supplies accessible from anywhere on the LAN, supporting remote-lab and shared-equipment workflows. With configurable baud rates up to 115200 bps and hardware-accelerated TCP throughput, the module preserves SCPI command responsiveness while eliminating physical USB-to-serial cabling. The WIZ100SR's 0 °C to +80 °C commercial operating range and on-board PHY/RJ45 simplify lab-instrument integration without thermal management, and the WIZnet Configuration Tool allows per-instrument IP provisioning in seconds.
Empfohlen
Remote Sensor Data Acquisition
The WIZ100SR enables environmental and utility sensors with serial output to be aggregated and forwarded to a central server over Ethernet, fitting weather stations, water-quality monitors, and energy-meter clusters. Its UDP mode is well suited to periodic sensor broadcasts, while TCP Client mode supports polled data acquisition from a host SCADA system. With 16 KB per-socket buffers inside the W5100 silicon and a 0 °C to +80 °C operating range, the WIZ100SR handles sustained serial-to-Ethernet traffic without dropped packets, and the 3.3 V supply allows direct battery-backed operation in remote enclosures with a small DC-DC regulator.
Empfohlen
Medical Device Connectivity
The WIZ100SR's transparent RS-232 tunneling supports medical-instrument integration where legacy diagnostic or monitoring devices must report to a centralized EMR/HIS system. Its hardware-offloaded TCP/IP stack on the W5100 silicon delivers reliable bidirectional data with deterministic latency, while the 0 °C to +80 °C commercial operating range suits climate-controlled clinical environments. Compared with general-purpose IoT modules, the WIZ100SR provides a long-life, well-documented firmware base that simplifies IEC 62304 documentation reuse. Designers typically pair the module with a USB-isolator or RS-232 isolator to meet IEC 60601-1 patient-leakage requirements.

Designhinweise
Provide a clean 3.3 V DC rail rated for at least 250 mA peak (W5100 burst + PHY link pulses) to the WIZ100SR supply pins. Place a 10 µF tantalum or ceramic bulk capacitor plus a 0.1 µF ceramic decoupling capacitor within 5 mm of the module supply pins to suppress the high-current transients that occur during Ethernet link-up. A ferrite bead between the 3.3 V source and the module helps isolate noise injected back into upstream regulators from the on-module PHY.
Allocate at least 1 square inch of copper pour beneath the module for thermal spreading and ground return. The integrated RJ45 jack already includes the Ethernet magnetics, so no external transformer is required; however, route the RS-232 TX/RX traces as a matched differential pair with 50 Ω characteristic impedance and keep them short and away from the RJ45 area to avoid coupling 100 MHz Ethernet harmonics into the serial path. Stitch ground vias around the module perimeter every 5 mm for EMI containment.
Do not assume the WIZ100SR accepts 5 V on its serial pins - the W5100 silicon and on-board 8051 are 3.3 V tolerant and the RS-232 transceiver is TTL-level, not true RS-232 voltage levels. Use an external MAX3232 or similar level translator when connecting to a true RS-232 port (±12 V). Also avoid sending configuration-mode escape sequences on power-up without first de-asserting RESET for at least 100 ms, otherwise the module may boot into firmware-update mode and ignore application traffic.
The WIZ100SR's W5100 silicon dedicates 16 KB of TX/RX buffer per socket, but TCP throughput still depends on socket-window tuning and serial-side flow control. Enable hardware (RTS/CTS) or XON/XOFF flow control when bridging high-speed serial traffic above 57600 bps to prevent UART FIFO overruns, and configure TCP no-delay (Nagle off) for command/response SCPI applications. For UDP broadcast sensor streams, set an application-layer sequence number to detect packet loss and recover.
