Specifications and Ordering Info
The EM203 has several versions available. Device numbering scheme is as follows:
Examples of valid model numbers
Model number |
Description |
EM203-00 |
Connector configured to mate with the EM203 jack/magnetics module, the module will be supplied with the "serial-to-Ethernet" firmware |
EM203-D-00 |
Connectors configured to mate with the host PCB, the module will be supplied with the "serial-to-Ethernet" firmware |
EM203-DP-00 |
Connectors configured to mate with the host PCB, the module will be supplied with the TiOS firmware |
Ordering the EM203 and RJ203 module combination
The EM203 can also be ordered in combination with the RJ203 module. To receive these two modules pre-assembled together, please specify "RJ203+EM203" on your order if you wish to receive the EM203 with the "serial-to-Ethernet" firmware preloaded, or "RJ203+EM203-P" if you wish to receive the EM203 with the TiOS firmware preloaded.
