Received Signal Strength Indicator (RSSI):
The radio communications board has a signal strength indicator on the right hand edge to show the
level of the signal that was received from another radio. The indicator consists of 3 LED’s labeled SS1,
SS2 & SS3. It is desirable to operate with the highest signal strength achievable. If the signal strength
is less than -90dBm, it is advisable to try to make adjustments to the system to bring the signal strength
up. A higher power setting on the radio or a higher gain antenna can be used to increase signal
strength and achieve more reliable operation of the radio system.
