Chapter 4: Connecting External Equipment (Optional)41For the cabling length restrictions, see Supported Maximum DPXSensor Distances (on page 45).Warning: For proper operation, wait for 15-30 seconds between eachconnection operation or each disconnection operation ofenvironmental sensor packages.To connect a DPX sensor package with a factory-installedsensor cable: Plug the sensor cable's RJ-12 connector into the RJ-12 SENSORport on the EMX.To connect a DPX differential air pressure sensor:1. Plug one end of a Raritan-provided phone cable into the IN port of adifferential air pressure sensor.2. Plug the other end of this phone cable into the RJ-12 SENSOR porton the EMX.3. If intended, connect one DPX sensor package to the OUT port of thedifferential air pressure sensor. It can be any DPX sensor package,such as a DPX-T3H1.The EMX deviceRaritan differential air pressure sensorsOne DPX sensor package (optional)
