Embedded EtherNet/IP Module
GS11-EI
7
If this pin is pull down to low voltage before starting the module (by using a 1K
pull-down resistor), the module will start with default IP address (192.168.0.11), and
this mode is only used to update the firmware.

/DATAEXCH
Data Exchange (Output), and need a 10K pull-up resistor on the user board.
Logic 1: The module is in non-data exchange state (such as start state, waiting for
initialization state, start the EtherNet/IP protocol stack, etc.)
Logic 0: The module is ready for data exchange.
