The "Pre-Input Character Translation Table" in the Wedge
allows you to translate ASCII characters to other characters before
arriving in the Wedge. Typically, this feature is used to convert
delimiter characters so that they will all be the same character
when the Wedge receives the data. For example, suppose you had a
device that transmitted the following data record:
123.53, 46.20, 03:45:21<CrLf>
In the above data record there are two different delimiter
characters being used, the comma and the colon. If you translated the colons to commas in
the "Pre-Input Character Translation Table", then the data record would appear
to the Wedge as:
123.53, 46.20, 03,45,21<CrLf>
Now that all the delimiters are the same, you could define
the record structure in the Wedge as "Multiple Delimited Data Fields" using the
comma as the delimiter with five fields in each record.
The "Pre-Input Character Translation Table" also
allows you to translate characters to either "Ignore" or "Void
Record". The "Ignore" translation simply removes the character from the
input data as if the character did not exist. The "Void Record" translation
causes the Wedge to disregard the entire current data record if a character that has been
translated to "Void Record" appears anywhere within the record. This feature can
be used reject certain data records from a device. For example, suppose you had a device
that transmitted the following data:
Device# Height Width Length <CrLf>
---------------------------------------------------------
<CrLf>
1 23 12 24 <CrLf>
2 27 13 8 <CrLf>
3 27 13 9 <CrLf>
4 27 13 8 <CrLf>
---------------------------------------------------------
<CrLf>
Since you are probably not interested in the first line or the
lines containing the dashes, you could use the "Void Record"
translation to remove these lines by translating the dash character
and the uppercase "D" to "Void Record". After
the translations, the Wedge would send the data as shown below:
1 23 12 24 <CrLf>
2 27 13 8 <CrLf>
3 27 13 9 <CrLf>
4 27 13 8 <CrLf>
