RSSI Monitoring Interface
The RSSI voltage is a function of the signal strength at the receiver and is used to measure the received
signal strength. RSSI varies from approximately 0 to 5 VDC. An RSSI calibration sheet is shipped with the
system to provide the installer a cross-reference between actual received signal level (in dBm) and RSSI
voltage. This sheet is useful for verifying link budget calculations and ensuring proper equipment
installation.
