OpenComms EM

The OpenComms EM is a compact device designed to monitor temperature, humidity and contact closures and notify personnel when conditions exceed user-defined limits. The OpenComms EM takes up zero U rack space and can support any combination of two sensors. The supported sensors are temperature, humidity, temperature & humidity combination and contact closure. The EM PDU Controller version has two sensor ports and two serial ports for connection to the Liebert Managed Power Advanced Power Strips.

The vEM-14 is a 1-U rack mountable device that uses the same sensors and has the same features with additional inputs as the OpenComms EM device. A built in temperature & humidity sensor allows for the monitoring of the local temperature and humidity without the use of one of the sensor ports. The vEM-14 has 4 sensor ports, 2 serial ports, 1 internal temperature & humidity sensor and 10 dry contact inputs through the use of screw terminals.

The OpenComms EM supports a 10Mbit Ethernet connection and provides the following functionality: Web interface using HTTP, user authentication, e-mail and paging notification, SNMP support including Nform and graphing.
