PWR/ALM and ACTIVE LEDs
Solid RED – module is powered but is in reset or the BCP is inactive.
MMI Connectors
The RS–232 MMI port connector (four-pin) is intended to be used
primarily in the development or factory environment but may be used
in the field for debugging purposes.
The RJ–11 ethernet port connector (eight-pin) is intended to be used
primarily in the development environment but may be used in the field
for high data rate debugging purposes.
