S109
Hop Interval
This register is effective only on the Master and is responsible for establishing the
rate at which all modems within a particular network change frequency (hop - from
frequency to frequency).
Long hop intervals typically result in the greatest data throughput, however shorter
hop intervals may decrease latency, particularly of smaller packets of data.
The default setting of 20ms is satisfactory for most applications. If adjustment of
S109 is being considered, also consider the serial baud rate, wireless link rate, and
maximum packet size (S102, S103, and S112).
Hop Interval S109 should
only be changed if
recommended by
Microhard Support and/or
for specific applications!
