Set the modulation level for whole network. If Link Specific 
Modulation is used this set the basic modulation level. 

1.1997

Selects the used modulation method against neighboring 
radios. OFF = modulation is same for every neighbor and 
follows the value in “Modulation”. Manual = Modulation can be 
set differently to each neighbor as described in Central Units 
user manual. Auto = Modulation is adjusted automatically 
based on detected signal quality.

1.2045

OFF = Handshaking selection is same for all neighboring radios 
and follows the value in “Handshake”. ON = Handshaking 
can be selected differently for each neighbor as described in 
Central Unit user manual.

1.2046

OFF = Retransmission selection is same for all neighboring 
radios and follows the value in “Retransmissions”. ON = 
Retransmissions can be selected differently for each neighbor 
with Packet Routing table/Link quality selection.

1.2047

Set the offset to Automatic QAM modulation so that positive 
values will cause device to use lower modulation than normally 
selected based on detected SNR level. Negative values will 
cause selecting higher modulation than normally selected.
