REVIEWING THE FRONT PANEL DESIGN
The front panel contains
RSSI
monitoring interface, a
GND
interface for reference with RSSI, and status
LEDs to provide visual information about the TRACER 5045 system. Figure 1 identifies the various
bantam interfaces and the LEDs.

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 approximately from 0 to greater than 4 Volts (V), with 0V corresponding to a
weaker received signal and 4V or better corresponding to a stronger received signal.
signal strength. RSSI varies approximately from 0 to greater than 4 Volts (V), with 0V corresponding to a
weaker received signal and 4V or better corresponding to a stronger received signal.
Front Panel LEDs
With the TRACER 5045 powered-on, the front panel LEDs provide visual information about the status of
the TRACER 5045 system. Table 1 provides a brief description of the front panel features, and Table 2 on
page 27 provides detailed information about the LEDs.

page 27 provides detailed information about the LEDs.
The voltage level present at the
RSSI
test point represents only a relative signal level of
receive strength from the far end. No direct correlation can be made between RSSI voltage
levels and actual receive levels in dBm. This test point is provided to assess relative signal
level for alignment of antennas.
