TRACER 5045 System Manual

 

 

1.EQUIPMENT DIMENSIONS

The TRACER 5045 unit is 17.22” W, 9.34” D, and 1.72” H, weighs 7 lbs, and can be used in rack-mount configurations.

2.POWER REQUIREMENTS

The TRACER 5045 system has a maximum power consumption of 23 Watts and a maximum current draw of 1.1 Amps (at 21 VDC).

3.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.

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.

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.
