To use this feature, connect to the + desired unit (TeleLCO is probably the most useful place to + start) with a laptop and terminal program as explained in the + configuration section of the manual. Then, you can enable + debug tracing using 'D 1' command. + + Debug mode is fairly chatty, but each time the TeleLCO unit + queries the currently selected TeleFire unit for igniter + status, the return packet will print out the RSSI value. + RSSI is "received signal strength indicated" and is expressed + in decibel units relative to a milliwatt, or "dBm". + + Observing the RSSI is a great way to compare antennas, antenna + mounting arrangements, and so forth with more granularity than + provided by the red/amber/green operational LED indicators. + + The system is good down to about -100dBm, and it takes about + 6dB to double the range. So a reading of -84dBm means that you + could extend the distance between the units by a factor of + 10 before losing the link. Note, however, that real world + range is affected by terrain, vegetation, etc. |
