The Opengear EMD5000 environmental monitoring device plugs into the serial ports on our console servers and enables you to remotely monitor environmental conditions using a standard Web browser. 

You can view the ambient temperature and humidity of the remote environment and set the EMD to automatically send alarms progressively from warning levels to critical alerts. So you are warned if the temperature in a remote equipment rack begins to rise and can plan preventative action. Similarly, a warning of rising humidity in an air-conditioned room could be a sign of a duct leak, open door, roof leak, etc. The EMD also monitors the status of one or two external dry contacts which can be connected to a smoke detector, water detector, vibration or open-door sensor. 

The EMD connects to a serial port on any Opengear console server with an adapter and Cat 5 cable. Authorized users can securely monitor the environment at the remote site. Each EMD device has one temperature and one humidity sensor and provides one or two general purpose status sensors in one small module. Each console server can support multiple EMDs providing distributed monitoring any site. 

Note *EMD5000 only works with serial ports on Opengear console servers*
