The SINGLE CYCLE TRANSMIT feature can help you with this
process by uploading one piece of data at a time, allowing you to check
each field as it uploads.
3. Timing Delays for this field only
Timing delays of .10 seconds to 9.9 seconds can be programmed into
the
Upload Prefix
(and
Suffix
). This inserts a time delay before or after
a field of data, allowing your application to keep up with the data
coming from the TriCoder. This is especially important when
uploading directly into an application using the TriCoder as a keyboard
wedge. As well as giving your application time to process the data
coming from the TriCoder, delays also allow you to keep pace with
screen changes and avoid overloading the keyboard buffer. Delays are
often required when uploading into programs such as EXCEL. Timing
delays are programmed by scanning the DEL (ASCII 127) from the
Full ASCII Menu
, then entering two characters - use any combination
between 01 (.10 seconds) and 99 (9.9 seconds). Use as small a delay as
possible to avoid a slow upload.
UPLOAD PREFIX
01
?05_
The previous example shows a . 5 second delay.
4. Appending data to another field
A very common use of the
Upload Prefix
(or
Suffix
) is to append data
to a field every time that field is uploaded. Use the characters:
}xx
where
xx
is the number of the statement you want to attach. To save
space (you are allowed only 15 characters in a prefix or suffix), a single
digit can be used when the statement number is a single digit - }2 is the
same as }02 - as long as it is not followed by another valid digit.
As an example, let’s say you wanted to attach an aisle number as a
prefix to every item number you entered. Assuming the aisle number is
statement #02, entering }02 in the Upload Prefix of the item number
statement would attach the aisle number to every item number. Only
the data in statement #02 would be attached; any
Upload Prefix
or
Upload Suffix
characters for statement #02 will not be uploaded.
The field that is appended (#02 in our example) is typically not uploaded
by itself - it is only uploaded in conjunction with another field. To
suppress the transmission of a field entirely upon uploading, use:
~0
in the
Upload Prefix
or
Upload Suffix
(either will work) for that field.
