User data whitening

In some cases, if the user data includes large number of constant characters, additional bit
errors may appear. The use of error correction (FEC) is recommended in such cases. If that is not
possible, the Data whitening feature can be used to improve the reliability of data transfer. The
feature is set on/off in the programming mode

.

NOTE!

All radio modems, which are to communicate with each other, must have the same

setting for Data whitening (ON or OFF). If the transmitting radio modem and the receiving
radio modem has different settings, data will not be received correctly.
