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
