XLINK 500/100 Operations & Maintenance Manual page # 149
STATION and SENSOR and DATEFORMAT are tags that are always present.
000DOLPHIN is based on the Station Name which was set to DOLPHIN. The 000 are
padding to fill out to 10 bytes. If the Station Name were longer than 10 bytes, only the
first 10 would be in the STATION tag.
00PR is based on the measurement Label, which was set to PR. 00 is padding to fill out
to 4 bytes. Up to 4 bytes of the Label can fit into the SENSOR tag.
YYYY/MM/DD is the user set Date Format setting.
111500 is the timestamp in HHMMSS format which is 11:15:00
82.03 is the sensor reading. If data is missing, --- is transmitted.
15.9.
ASCII Column
The ASCII Column format is another means of encoding transmission data. A message formatted
with this method would look like this:
<CRLF>
Meas1_Data(1) Meas2_Data(1) ... MeasN_Data(1)<CRLF>
Meas1_Data(2) Meas2_Data(2) ... MeasN_Data(2)<CRLF>
Meas1_Data(n) Meas2_Data(n) ... MeasN_Data(n)<CRLF>
<CRLF> is a carriage return, line feed
Meas1_Data()..MeasN_Data are the data from the active measurements included in the
transmission.
All the data on one line are for the same time. A space separates the values. The newest
data is sent first.
(n) is the number of values included in the transmission as set by the user.
The format for any value is ASCII with the right digits set by the user.
No decimal point is shown if the value is zero.
Add a minus sign in front of the value if the value is negative.
There are no leading zeroes.
If the value is missing, two forward slashes are transmitted instead //.
A typical message will appear as follows:
41.79 60.99 12.99 12.43 .20 8.08 7.1 195.2
41.79 60.99 12.99 12.43 1.20 8.08 7.1 195.2
41.79 60.99 12.99 12.43 -2.20 8.08 7.1 195.2
Normally the DCP will be set up, so all the sensors are collected at uniform times. If this is not the
case, the formatter will still work but will have varying amounts of data on each line (each time)
based on whatever sensors are collected at each time. This will produce confusing results if the
additional sensors are collected at an interval of the other sensors. The results should be OK if
the additional sensors are collected at a time separate time.

ASCII Sensor
This method of formatting uses four digits for each measurement readings. Measurement
readings are multiplied by 100 before being transmitted.
