is an integer that indicates the averaging duration, in 1ms increments, for the
LS8500-4's measurements. A value of zero enables automatic averaging where the aver-
aging time equals the
User Update Rate .
The LS8500-4 generates a new velocity and length measurement, updates the pulse out-
put 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 that specifies, in milliseconds, how often the LS8500-4 transmits data over the
serial/Ethernet port. For example, an O setting of 32 would cause the LS8500-4 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 LS8500-4
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.
