Connecting Differential Air Pressure Sensors
You can have a Raritan differential air pressure sensor connected to the
EMX device if the differential air pressure data is desired.
With this sensor, the temperature around the sensor can be also
detected through a temperature sensor implemented inside it.
Multiple differential air pressure sensors can be cascaded.
To connect differential air pressure sensors:
1. Plug one end of a Raritan-provided phone cable to the SENSOR port
of the EMX device.
2. Plug the other end of this phone cable to the IN port of the differential
air pressure sensor.
3. To connect additional Raritan differential air pressure sensors, do the
following:
a. Plug one end of a Raritan-provided phone cable to the OUT port
of the previous differential air pressure sensor.
b. Plug the other end of this phone cable to the IN port of the
newly-added differential air pressure sensor.
c. Repeat Steps a to b to cascade more differential air pressure
sensors. Note that each SENSOR port supports a maximum of
16 environmental sensors.
