3.5.1 Temperature and Humidity Sensor
Temperature and Humidity Sensor Types
The SNMP card supports temperature and humidity sensor. The model of the temperature and
humidity sensor is ENR1DETA MODULE.
If the SNMP card is equipped with a temperature and humidity sensor, you can view the UPS
temperature and humidity on the Monitoring page, as shown in Figure 4-9. If the SNMP card is not
equipped with a temperature and humidity sensor, NA is displayed.
According to the temperature and humidity sensor document, set the temperature and humidity
sensor address to 1 (toggle switch 1 is ON and other toggle switches are OFF for ENR1DETA
MODULE, as shown in Figure 3-3) and baud rate to 9600.

RJ11 Terminal
The temperature and humidity sensor connects to an SNMP card over a symmetric twisted
pair. If the sensor model is ENR1DETA MODULE, both ends of the twisted pair are RJ11
terminals.
Insert the one end (RJ11 terminal) of the temperature and humidity sensor cable to the
TEM_HUM port on the SNMP card, and the other end to the temperature and humidity
sensor. For the method about how to connect the other end of the cable, see the user manual
related to the temperature and humidity sensor. Figure 3-4 shows the RJ11 terminal.
