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 Volts DC (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.

Front Panel LEDs

With the TRACER 4102/4202 powered-on, the front panel LEDs provide visual information about the status of the
TRACER 4102/4202 system. Table 1 provides a brief description of the front panel features, and Table 2 provides
detailed information about the LEDs.
