with the channel number indicated by the first two digits. The measurement unit this data
represents is controlled by the full scale parameter for each channel. If that parameter is set
in Bar then this number will be in Bar, etc.
Example:
01: 0003.4567
In streaming mode then the data can be output either as ASCII text or as binary data. For
data rates below 40 samples/second/channel any of these formats can be used but for higher
data rates the KMPS will only be able to keep up using binary output. To select a format use
the FOrmat command followed by the name of the format. See section 4.3 on header
information for all formats.
In streaming mode data is acquired eight channels at a time (see section 2.0 for more details).
For an RS-485 scanner this data is then immediately sent over the bus. For an Ethernet
scanner the data for all of the selected channels is accumulated and sent in a single packet.
In UDP mode the packet structure is preserved so that parsing is fairly straight forward. In
RS-485 and TCP mode it is recommended to use the synchronization stamp in order to avoid
losing your place.
4.2.1 TExt format
Data is output in engineering units based on the selected pressure unit. A two digit channel
is output followed by a colon and then an 8 character number with the decimal location
dependent on the full scale of each channel. A carriage return ends each line.
Maximum data rate for Ethernet Text format is 125 samples/second. Maximum data rates for
RS-485 depend on baud rate.
Example:
00: 123.456
08:-00.1234
4.2.2 TExt PErcentage format
Data is output as a percentage of full scale pressure. All spaces and decimal points are
omitted to save characters. The two digit channel is followed by a five digit number which is
percentage of full scale output times 100. The data can be converted to engineering units in
post processing by multiplying by the full scale setting for each channel (read using the
FUllscale command)
Example:
0000234
0802567
1610134
This partial data set represents Channel 0 being at 2.34% of FS, Channel 8 being at 25.67%
of FS, and Channel 2 being at 101.34% of FS. Note the data can go above 100% of full scale
however this data may not meet the accuracy standards of the data within the range and will
eventually saturate. Negative numbers represent differential pressures in the opposite
direction. For outputs below 100% of fullscale a 9 is used to avoid changing length. Eg
0390123 means that channel 3 is at -101.23% of full scale.
Maximum data rate for Ethernet Text Percentage format is 125 samples/second. Maximum
data rates for RS-485 depend on baud rate.
