D - Data Order Data Order [Scan ]
This option defines if data will be sent based on each transmitted line representing a single scan
or each transmitted line representing a single channel or sensor.
Scan Order: Each line of data represents one scan and one value from each defined input.
HG TA VB
18.34 22.78 12.45
18.76 22.45 12.44
18.97 22.15 12.45
19.43 22.02 12.45 SHEF headers turned on.
Stage, Temp, and Battery values in each line.
Each line is a different scan at some defined
time interval.
Channel Order: Each line represents all the data from a single sensor.
HG 18.34 18.76 18.97 19.43
TA 22.78 22.45 22.15 22.02
VB 12.45 12.44 12.45 12.45 Each line has all data from a single
sensor. Each value in the line is scanned
at different times based on scan rate.

N - Data Sent First Data First [Newest]
This option defines if the ‘Newest’ or ‘Oldest’ data should be sent first. Some decode programs
only accept the data in one format and not the other.

H - Send SHEF Headers Send SHEF Codes [No ]
The system uses this option to see if SHEF codes are to be included in the data transmission.
The SHEF code is a two character code that represents the data. For example the standard SHEF
code for the stage data is HG for height of the gauge or TA for ambient temperature. The SHEF
codes may be useful in decoding and although SHEF codes can be defined and transmitted, no
attempt was made to hold to the SHEF code format. Sending the SHEF code will add time to the
transmission so it may cut down on the amount of data transmitted.
SHEF stands for ‘Standard Hydrometeorological Exchange Format’ (SHEF). This is a
documented set of rules for coding of data in a form for both visual and computer recognition. It
