The EM100 is Tibbo's original 10BaseT serial-to-Ethernet converter for onboard installation — it all started from this orange module.
The Ethernet- to-serial EM100 has on-board magnetics and requires only one external component — an RJ45 Ethernet connector.
The module is fully sealed (potted) for maximum environmental protection.
The EM100 ethernet converter is compatible with Tibbo Device Server Toolkit (TDST) for Windows. TDST includes the Virtual Serial Port Driver (VSPD), which enables you to use the serial port of the module as a remote COM port of your PC. The Linux version of the VSPD is available as well.
