The EM203 module is a miniature serial / Ethernet embedded converter. In combination with a transformer decoupled RJ203 connector, the EM203 takes up only 31x19mm board space. The EM203 can also be used with any available connector with transformer decoupling.
The EM203 comes with the Tibbo Device Server Toolkit software, which includes the Virtual Serial Port Driver Virtual COM Port Driver for Windows and Linux operating systems.
The EM203 can also be supplied with TiOS-loaded firmware and works as a simple BASIC-programmable controller. The module can be ordered in combination with an RJ203 connector.
