Port
Used for...
FEATURE
Connection to asset sensors via a Category 5e/6 cable.
Note: The EMX device supplies power to the connected asset sensors after
the connection is established.
CONSOLE/
MODEM
Establishing a serial connection between a computer and the EMX device:
This is a standard DTE RS-232 port. You can use a null-modem cable with
two DB9 connectors on both ends to connect the EMX device to the
computer.
SENSOR
Connection to Raritan's environmental sensors.
A Raritan sensor hub may be required if you want to connect more
environmental sensors.
ETHERNET
Connecting the EMX device to your company's network:
Connect a standard Cat5e/6 UTP cable to this port and connect the other
end to your network. This connection is necessary to administer or access
the EMX device remotely using the web interface.
There are two small LEDs adjacent to the port:
Green indicates a physical link and activity.
Yellow indicates communications at 10/100 BaseT speeds.
For a USB-cascading configuration, the wired connection is a must for the
master EMX. See Cascading the EMX via USB for details.
Note: Connection to this port is not required if the EMX device is connected
to a wireless network.
RS-485
Connection to an electrical device with the RS-485 interface. Currently the
EMX only supports the Schroff

LHX-20 and LHX-40 heat exchangers.
