The TRACER 4108/4208 unit is 17.12” W, 10.80” D, and 1.72” H and can be used in 19 or 23-inch rack-mount 
configurations.

The TRACER 4108/4208 system has a maximum power consumption of 21 Watts (TRACER 4108) and 18 Watts 
(TRACER 4208) and a maximum current draw of 0.86 Amps (at 21 VDC).

The front panel contains 

 and 

 monitoring interfaces, a 

 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).

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.

The 

 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).
