When data flow on the TD line starts the frequency shifts from the receiving channel to the
transmit channel. There is a 40 ms delay caused by the frequency shift before the actual data
transmission sequence starts, and the same time is needed for the return to the receive channel
after transmission.
The selected channel spacing, port settings etc. are equal to both frequencies.
The dual radio settings can be adjusted also by the SL commands.

Free Channel Scan (FCS)
Free Channel Scan (FCS) is designed for one-way transmission between one transmitter and one
or more receivers when there are at least two different radio frequencies available. The transmitter
monitors the noise level of the channels between the transmissions and finds the best transmission
channel. The receivers scan and follow the frequency of that particular transmitter consequently.
The feature is beneficial e.g. for the applications in land surveying or when license free channels
are used and there could be other transmitters using the same channels.
To make the use easier SATEL provides the FCS terminal software for your PC. Using the program
it is easy to configure the radio modems to use the FCS function. There is also a scanning tool
for measuring the power level of the selected radio channels. A more detailed description of FCS
function and FCS terminal software is available from the manufacturer or from the nearest
distributor.
