is an integer from 0 to 2047 that indicates the number of milliseconds of averaging for
the LS8000-3's measurements. This value should be set to 0 by default. This enables
automatic averaging.
The LS8000-3 generates a new velocity and length measurement, updates the pulse output
frequencies, and updates the analog output every 1ms. This setting controls the length of
the moving average used to calculate the 1ms reading.

is an integer from 0 to 2047 that specifies, in milliseconds, how often the LS8000-3
transmits data over the serial/Ethernet port. For example, an O setting of 32 would cause
the LS8000-3 to transmit data every 32 milliseconds. Some typical update rates are:
O Rate Command
4 ms Fast
O4<CR>
32 ms Medium O32<CR>
100 ms Slow
O100<CR>
Depending on the baud rate, when using fast update rates, it may not be possible for the
LS8000-3 to complete transmission of an entire measurement update before it is time to
transmit the next one. If this occurs, the late measurement will not be transmitted. See the
Serial Real-Time Data Timing section for further details.
