CHAPTER FOUR – DATA CAPTURE

Checking on Symbology Reading
There is a ‘NID Scanner’ applet in the control panel which provides a ‘Scan’
page for checking on symbology reading. On the ‘Scan’ page, it is possible to read
a bar code or a 2-D code pattern by directing the aimer light (either laser beam or
LED light) emitted by the scanner at the tag after pressing the ‘Scan’ key.
Before you begin, check that the symbology is enabled and its options are
selected properly; see the sections ‘Enabling / Disabling Symbology’ below and
‘Configuring Specifics of Symbology’ on the next page.
The tab shows scanning result in its output fields as follows:
Field
Description
Result String
When the scan succeeds the field
shows the decoded result, that is, the
machine-readable symbol in the
human-readable form
Result Info
The field tells whether the scan
operation ended in success or in failure
1
st
field: AIMSI
When the scan operation succeeds the
combination of three characters is
shown in this field. The first character
is a flag. (It informs that AIM code
follows next in the character string
received from the scan engine.) The
character after the flag tells the type of
the symbol, and third one is a modifier
character.
2
nd
field: Mod
char
The modifier character out of the three
character AIM symbology identifier tells
how the reader interpreted the symbol.
(The modifier character, that is, the
interpretation is pertinent to the
symbology type.)
AIMSI
(AIM Symbology
Identifier)
3
rd
field: Type
When the scan succeeds this field tells
the type of the decoded symbol in the
understandable form
Enabling / Disabling Symbology
On a ‘Codes’ page, the ‘NID Scanner’ control panel applet lists all the
symbologies the applet supports (not necessarily all the symbologies the scanner
supports). Each list item has a check box telling whether or not the reader decodes
the code type when the particular type of code is being scanned. By default, the all
the symbologies that the ‘Codes’ page shows are enabled.
