Figure 2-11 Making Connections to Storage Battery
2.3.2 RF Antenna Connections
The transmit and receive antenna RF connections are made using two separate N-type connectors.
Coax cables from the receive and transmit antennas must be connected to the two N-type
connectors. The position of these connectors is shown in Figure 2-10.
In the case where an optional Antenna Relay is used on the base station/repeater, the coax cable
from the single transmit/receive antenna is connected to the middle N-type connector of the Antenna
Relay.
2.3.3 System Cable Connections
System connections are made through one or both of the following connectors:
• Auxiliary System Connector
• System Connector
The location of the Auxiliary System Connector and System Connector on the base station/repeater
rear panel is shown in Figure 2-10.
Table 2-5 provides a description of commonly used J7 Auxiliary System Connector pins.
Table 2-6 to Table 2-8 provides a description of the J5 System Connector pins.
NOTE: (*) Indicates an active low signal.
Connector ESD cover must be in place when Battery Backup cable is not in use
– to prevent exposure to live contacts.
DC input Connector located at rear of
the station for hooking up the Battery
backup system.
Required input power:
• Voltage - 28.4 VDC
• Current - 13.0 Amps
