Response: 3225,4538<CR>

Meaning: Internal Temperature: 32.25ºC

Maximum Internal Temperature: 45.38ºC

K Averaging Time

K<CR> Read

Response Format: <N>

K<N><CR> Set

<N> 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.

O User Update Rate

M<CR> Read

Response Format: <N>

M<N><CR> Set

<N> 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.
