RSSI LED PLUG ADAPTER
Antenna Alignment using RSSI LED Plug Adapter
The RSSI LED Plug is a small adapter that allows you to accurately position (align) the ProST for
optimal radio frequency signal reception with the Base Station. The RSSI LED Plug adapter provides
LEDs that indicate the ProST's received signal strength (RSS) with the Base Station.
Once the RSSI LED Plug adapter is connected, you need to orientate the ProST (or third-party
external antenna) to the position where the RSSI LEDs display the highest RSS measurements.
The RSSI LED Plug adapter connects between the ProST and SDA by a CAT 5 cable(s). The RSSI
LED Plug adapter provides two 15-pin D-type ports: one for the ProST side, and the other for the
SDA side.
The RSSI LED Plug adapter can be connected in one of the following manners:
One end connects directly to the ProST's 15-pin D-type port, and the other end connects to
the SDA (IDU adapters) by a CAT 5 cable.
Both ends connect to the ProST and SDA by a CAT 5 cable.
The following describes the RSS LED Plug adapter's cable setup:
Cables: two straight-through cables for connecting the RSSI LED adapter to both the SDA
and ProST
Connectors:
o ProST side: 15-pin D-type male (only 6 pins used)
o RSSI LED Plug adapter:
o ProST side: 15-pin D-type female
o SDA side: 15-pin D-type male
o SDA side: 15-pin D-type male
