REVIEWING THE FRONT PANEL DESIGN
The front panel contains
RSSI
and
TX PWR
monitoring interfaces, a
GND
interface for reference with the
monitoring interfaces, and status LEDs to provide visual information about the TRACER 4108/4208 system.
Figure 1 identifies the various bantam interfaces and the LEDs on a TRACER 4208 front panel. The TRACER
4108 front panel is identical (with the TRACER 4108 product label).

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 5 Volts (V).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.

TX PWR Monitoring Interface
The
TX PWR
voltage is a function of the selected transmit power level. This voltage ranges approximately from
0 to 5V, with 0V corresponding to +5 dBm (3 milliwatts) and 5V corresponding to +20 dBm
(100 milliwatts).
