3.2.1 Main Hub Rear Panel Connectors
3.2.1.1 N-type Female Connectors
There are two N-type female connectors on the rear panel of the Main Hub:
•The
UPLINK connector transmits uplink RF signals to a repeater, local base sta-
tion, or MetroReach Focus system.
•The
DOWNLINK connector receives downlink RF signals from a repeater, local
base station, or MetroReach Focus system.
3.2.1.2 9-pin D-sub Connector
The 9-pin D-sub connector (labeled DIAGNOSTIC 1) provides contact closure for
major error and minor error system alarm monitoring.
The following table lists the function of each pin on the 9-pin D-sub connector. Pin
locations are labeled on the figure.
This interface can either generate contact alarms or sense a single external alarm con-
tact.
