The NTI E-STHSM-E7 is a Probe-Style Temperature/Humidity/Dew Point Sensor for use with E-2D/5D/16D. The Network Technologies Inc (NTI) ENVIROMUX Series monitors critical server room and data center conditions like temperature, humidity, water leaks, power, smoke, and security intrusion, alerting administrators via SNMP, email, or SMS when thresholds are breached. The temperature and humidity sensors for the E-16D/5D/2D and E-SEMS-16(U) Enterprise Environment Monitoring Systems have RJ45 connection ports. Connect each sensor to one of the female connectors labeled "RJ45 Sensors" on the ENVIROMUX using CAT5 cable. The male RJ45 connectors should snap into place. (See page 12 for wiring specification and pinout.) The CAT5 cable that connects the sensor to the ENVIROMUX can be up to 1000ft in length (except for E-STHS-LCDW, which is limited to 150ft).
