Ordering Info and Specifications
This is a legacy product. The following is provided as it was documented originally, albeit with some corrections and changes for clarity and style.
The EM203A has several versions available. Device numbering scheme is as follows:
Examples of Valid Model Numbers
Model number |
Description |
EM203A-00 |
Connector configured to mate with the EM203A jack/magnetics module, the module will be supplied with the "serial-to-Ethernet" firmware |
EM203A-D-00 |
Connectors configured to mate with the host PCB, the module will be supplied with the "serial-to-Ethernet" firmware |
EM203A-DP-00 |
Connectors configured to mate with the host PCB, the module will be supplied with the TiOS firmware |
Ordering the EM203A and RJ203A Module Combination
The EM203A can also be ordered in combination with the RJ203A module. To receive these two modules pre-assembled together, please specify "RJ203A+EM203A" on your order if you wish to receive the EM203A with the "serial-to-Ethernet" firmware preloaded, or "RJ203A+EM203A-P" if you wish to receive the EM203A with the TiOS firmware preloaded.
