RS-232 DATA RECORD FORMATS
There are four possible data records for the KATC-V:
Ratio Error and Minutes
Ratio Error and Milliradians
Ratio Correction Factor and Minutes
Ratio Correction Factor and Milliradians
Data files of KATC-V data are written in ASCII format and can be printed as ASCII files.
They will appear in the same formats as the examples shown later in this document.
Each record of data will be stored as one long string of bytes. Thus, to locate a
particular field of data, you must know in which byte it begins. The record layouts given
here show the
exact
byte locations for the data fields in each of the four records.
All data records are of
fixed
format. Each record is 218 bytes in length.
Included in this document is an example of each type of KATC-V record, in ASCII
format and record layout. {CR}{LF} indicate 2 bytes in the record for Carriage Return
and Line Feed at the end of each line. To provide blank lines, extra {CR}s and {LF}s
are inserted.
In the record layouts, the data fields are delimited by a double line (
5
). The first byte
of each field is indicated by the byte position above it.
Also in the record layouts:
* = {CR} CARRIAGE RETURN (hexadecimal 0D)
# = {LF} LINE FEED
(hexadecimal 0A)
