WaveNet Link AX Installation and Operations Manual
2.3
User Interfaces
The Link AX provides user interfaces for fused DC power connection, electrical grounding,
radio frequency (RF) antenna connection, ATM25 connection, configuration and RSSI output.
The following provides information on each interface.
Outdoor Unit
•
Data/Power Cable
- Siamesed CAT-5 ATM25 and power cables.
•
RSSI
- BNC type connector for RSSI measurement.
•
Antenna (RF) Connector
- N-type female connector used for connection with antenna.
Note: There is no N-Type RF connector used on ODUs with integral antennas.
•
Main Power
- The Link AX is designed to work from a power input of 21 to 56 VDC.
•
Grounding Connector
- The ODU is equipped with an M5 ground screw and associated
washers. This ground screw serves as the proper chassis-ground connection point for an
external ground source. The Link AX must be grounded in accordance with the electrical
codes, standards, and practices governing the local installation.
•
Configuration Switch -
Configuration of the Link AX is performed via a DIP switch on the
ODU. The 10-position DIP switch is accessible by removing the water-tight dust cap on
the ODU. Once exposed, each of the 10 switches can be manipulated using tool that is
provided with the mounting kit.

ODU Performance Monitoring
RSSI (Receive Signal Strength Indicator) - A voltage provided through a BNC connector on
the outside of the ODU. The RSSI port is used for antenna alignment during installation and
for periodic measurement of Receiver/Path performance. The RSSI voltage in relation to the
receive signal level ranges from -30 dBm to -90 dBm.
