8.3.1 Connecting the EMD
The Environmental Monitor Device (EMD) connects to any serial port on the console server via a
special EMD Adapter and standard CAT5 cable. The EMD is powered over this serial connection
and communicates using a custom handshake protocol. It is not an RS-232 device and should not
be connected without the adapter:
Plug the male RJ plug on the EMD Adapter into EMD and
then connect it to the console server serial port using the
provided UTP cable. If the 6-foot (2-meter) UTP cable
provided with the EMD is not long enough, you can
replace it with a standard CAT5 UTP cable up to 33 feet
(10 meters) long.
Screw the bare wires on any smoke detector, water
detector, vibration sensor, open-door sensor, or general
purpose open/close status sensors into the terminals on
the EMD.
