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.
Front Panel LEDs
With the TRACER powered-on, the front panel LEDs provide visual information about the status of the
system. Table 2 describes the LEDs.

For these LEDs... This color light... Indicates that...
PWR Green (solid) the TRACER is connected to a power source.
Off the TRACER is not currently powered up.
TEMP
*TRACER 64x0 high
power system only
Green (solid) the TRACER 64x0 high power system temperature is within
normal range.
Red (solid) the TRACER 64x0 high power system has an active temperature
alarm.
FAN
*TRACER 64x0 high
power system only
Green (solid) the TRACER 64x0 high power system fans are working properly.

TST
*TRACER 6420 (L1) only
Amber (flashes once) power-up self-test is in progress. If the LED continuously flashes
or remains on (solid) after 10 seconds, the unit has failed
self-test.
