2 Overview of the EMU
About This Chapter
Applicable to all types of BTSs/NodeBs manufactured by Huawei, the EMU is used to monitor
the environment in the equipment room.
2.1 Functions of the EMU
This describes the functions of the environment monitoring unit (EMU). Providing a variety of
input ports for monitoring signals, the EMU supports real-time monitoring and remote
monitoring. In addition, the EMU is highly reliable and can be flexibly configured. It supports
a large area for temperature monitoring.
2.2 Exterior of the EMU
This describes the exterior of the two EMU models.
2.3 Internal Structure of the EMU
This describes the internal structure of the EMU.
2.4 Communication Ports on the EMU
The EMU provides the RS485 and RS232 ports for the communication between the EMU and
the BTS/NodeB.
2.5 Monitoring Ports of the EMU
The EMU provides monitoring ports for the humidity/temperature sensor, smoke sensor, water
sensor, infrared sensor, and door status sensor. In addition, the EMU provides monitoring ports
for the Boolean signal sensor, analog signal sensor, and output control sensor, which are extended

2.1 Functions of the EMU
This describes the functions of the environment monitoring unit (EMU). Providing a variety of
input ports for monitoring signals, the EMU supports real-time monitoring and remote
monitoring. In addition, the EMU is highly reliable and can be flexibly configured. It supports
a large area for temperature monitoring.
Power Input
lThe EMU supports input voltage detection. The alarm threshold for the input voltage can
be configured on the BTS/NodeB and delivered to the EMU.
lThe EMU provides two power input ports, which are protected from inverse connections.
lThe range of voltage input is -36 V DC to -72 V DC.
Environment Monitoring
lThe EMU provides an independent port for 12 V/24 V DC current-type (4 mA - 20 mA)
humidity/temperature sensors. The temperature monitoring range is -20oC [-4oF] to 80oC
[176oF].
lThe EMU provides four ports for monitoring analog signals. Voltage-type (0 V - 5 V)
sensors and current-type (4 mA - 20 mA) sensors can be used. The types of monitored
analog signals can be configured through the DIP switch settings according to the BTS/
NodeB configuration.
Boolean Signal Monitoring
The EMU provides 32 ports for monitoring Boolean signals. Dry contact point signals and OC
signals are supported.
Relay Node Control
The EMU provides six output control ports for external Boolean signals of the relay node type.
Communication Ports
The EMU provides two RS-485 ports, which is used for the communication between the EMU
and the BTS/NodeB.
2.2 Exterior of the EMU
This describes the exterior of the two EMU models.
