Figure 7. TRACER Link Performance History

The minimum received signal level (MIN RSL) represents the minimum value of received signal level in a 24-hour or 15-minute increment and is displayed as a numerical value from 0 to 255 with 0 corresponding to 0 Volts of RSSI and 255 corresponding to 5 Volts RSSI.

The minimum receive signal level is recorded to aid in troubleshooting problem RF links. Radio links with high MIN RSL numbers and intermittent performance are probably experiencing interference, while links with low MIN RSL numbers have improperly engineered paths or excess system losses. A system with MIN RSL numbers varying widely indicates an intermittent installation problem such as loose connectors, damaged coax or lightning arrestors, or water contaminated feedlines.

Link errors (LNK ERR) represent errored seconds across the wireless link, and are generally an indication of path or interference problems.

The link error count and minimum received signal level for the most recent 24 hours are recorded in

15-minute increments and displayed on the right side of the page. The left side of the page displays the 24 hour totals for the most recent 7 days.

Press <N> to view the next 8 hours worth of 15-minute totals and <P> to view the previous 8 hours.
