Fusion Main Hub Rear Panel
Table lists the function of each pin on the 9-pin D-sub connector.
This interface can both generate two source contact alarms (Fault and Warning) and
sense 3 single external alarm contacts (Alarm Sense Input 1 through 3).
3.3.1.2 N-type Female Connectors
There are two 50 Ohm N-type connector pairs for each of the 3 bands on the rear
panel of the Hub:
• The
DOWNLINK connector receives downlink RF signals from a repeater, local
base station, or FlexWave Focus system.
• The
UPLINK connector transmits uplink RF signals to a repeater, local base sta-
tion, or FlexWave Focus system.
CAUTION:The UPLINK and DOWNLINK ports cannot handle a DC power
feed from the local base station. If DC power is present, a DC block must be
used or the Fusion hub may be damaged.
