Functions of the EMUAPower Input

The EMUA supports input voltage detection. The alarm threshold for the input voltage can beconfigured on the BTS/NodeB and delivered to the EMUA.

The EMUA provides two power input ports, which are protected from inverse connections.

l The EMUA2416 and EMUA2432 support +24 V DC power input, and the voltage canrange from +18 V DC to +36 V DC.

l The EMUA4832 supports -48 V DC power input, and the voltage can range from -36 VDC to -72 V DC.

Environment Monitoring

l The EMUA provides an independent port for +12 V/+24 V DC current-type (4 mA - 20mA) humidity/temperature sensors. The temperature monitoring range is -20oC [-4oF] to80oC [176oF].

l The EMUA 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 monitoredanalog signals can be configured through the DIP switch settings according to the BTS/NodeB configuration.

Boolean Signal Monitoring

The EMUA provides ports for monitoring Boolean signals. Dry contact point signals and OCsignals are supported.

l The EMUA2416 supports 16 ports for Boolean signal monitoring.

l The EMUA2432 or EMUA4832 supports 32 ports for Boolean signal monitoring.

Relay Node Control

The EMUA provides six output control ports for external Boolean signals of the relay node type.

Communication Ports

The EMUA provides two RS-485 ports, which are used for the communication between theEMUA and the BTS/NodeB.

l If a DIP switch bit is set to ON, itrepresents 0. If a DIP switch bit is set toOFF, it represents 1.

l The settings of the DIP switchSW_ADDR (1234) are as follows:– Outdoor CDMA BTS: 0000

– Indoor CDMA BTS or non-double-density GSM BTS: 0001

– Double-density GSM BTS, WCDMANodeB or LTE eNodeB or WiMAXBTS (the EMUA does not supportalarm association): 0010

– Double-density GSM BTS, WCDMANodeB or LTE eNodeB or WiMAXBTS (the EMUA supports alarmassociation)：1110

NOTE

l If an EMUA is delivered along with the BTS/NodeB, the communication protocol isalready configured according to the BTS/NodeB type.

l If an EMUA is delivered independently, thedefault setting of the DIP switch SW_ADDR(1234) is 0010.

l If an EMUA must support alarm association,the DIP switches must be set on site.

Procedure

Step 1 Perform a power-on check for the EMUA.1. Check the DIP switch settings.

For the correct DIP switch settings, see 2.3 Internal Structure of the EMUA.2. Power on the EMUA.3. Check the status of the indicators.

After power-on, both the red and green indicators should blink for about 0.5 second. Then,the red indicator should be off, and the green indicator should continue blinking.

Step 2 Check the communication between the EMUA and the BTS/NodeB.1. Ensure that the EMUA has passed the power-on check.2. On the Service Maintenance System of the BTS/NodeB, establish the communication

between the BTS/NodeB and the EMUA.3. Check the status of the indicators on the EMUA.

Check that the green indicator on the EMUA blinks once every two seconds.
