EM203 + - 100BaseT Ethernet-RS232 module (EM203 + RJ203)
EM203 + RJ203 form Ethernet 100BaseT - RS232. In the RJ45 connector size system, both the transformer and the RJ45 socket as well as four signaling diodes were integrated, being a fully complete device compatible down with the EM203A + and EM202 modules (dimensions and compatibility of the software). The system can be programmed using the tools provided by Tibbo or use the shared firmware.
The system is sold as a whole, it consists of:

The EM203 + module is the successor to the EM203A + module.
