Optimising the Antenna for Rx Signal
When using a directional antenna, it will be necessary to align the antenna to achieve optimal received signal. This can be done
using TView+ Diagnostics (measured RSSI) or by measuring the RSSI output on Pin 9 of the serial com port.
This can be done by using the (0-5Vdc) output on Pin 9 of the serial com port to indicate signal strength (RSSI). This voltage can
be converted to dBm using the chart below.
The RSSI output is a latched value of the received signal which is updated every 100mS.
