column will still be No.

Comp. : The compression factor of the data in the stream, expressed as

the number of bits occupied by each record (8, 16 or 32 bits.)

SPS : The sampling rate of the data stream, in samples per second.
Status streams, ending in 00, do not constantly output data and have

an SPS of 0. By default, the stream list is sorted in order of sample rate,
with the status streams at the bottom.

End time and Date : the date and time of the most recent data, as

measured by the data's own timestamp. This is not necessarily the
latest data to arrive.

RIC : The ‘Reverse Integrating Constant’. In effect this is the value of

the last sample received. This is most useful for reading mass positions
or other environmental streams. Status streams have a RIC of zero.

You can hide the extended information about each stream by selecting

Sorting options

Sorting options are available from the View Sort By

menu:

Alphabetical : Strict alphabetical order, 0 – 9 then A(a) – Z(z).

Component : Vertical components (ending Zx), followed by Nx and Ex

components, then Mux channels Mx. Within a component type, sort by
the first four characters of the Stream ID.

Instrument : Sort by the first four characters of the Stream ID. Within

an instrument, sort by tap, then by component.

Sample Rate : Sort by sample rate, highest to lowest. Within a sample
rate, sort as Instrument.

Tap : Sort by tap (the last character of the Stream ID.) Within a tap,

sort by instrument, then by component.

Select the Reversed option to reverse any of these sort orders.

You can also sort the list by Stream ID or SPS by clicking on the

relevant heading; click again to reverse the sort order.
