Installing the SPR Hardware Installation Guide
10.2.4. Aligning Using the RSS LED Adapter
You can align the SPR (or third-party antenna) using Airspan's RSS LED Adapter
once the SPR has established a wireless link with the BSR.
The RSS LED Adapter indicates the received signal strength (RSS) between the
SPR and the BSR. This allows you to accurately position the SPR during installation
for optimal radio frequency signal reception.
The RSS LED adapter connects between the SPR and SDA by a CAT 5 cable. The
RSS LED adapter provides two 15-pin D-type ports: one for the SPR side, and the
other for the SDA side.
The following table lists the RSS LED Plug adapter dimensions:
