NETUM Barcode Scanner: Prefix and Suffix Configuration Guide

Hide Prefix or Suffix Digits

This section details how to hide the start, middle, or end characters of a scanned barcode. After scanning the relevant hide barcode, scan a two-digit hexadecimal number to specify the length of characters to hide (e.g., to hide 4 characters, scan 04).

Hiding Barcode Characters

Hide Barcode Start Chars: Scan the command barcode for hiding start characters.

$SCAN#5

Hide Barcode Middle Char Start: Scan the command barcode for hiding the start of middle characters.

$SCAN#6

Hide Barcode Middle Chars: Scan the command barcode for hiding middle characters.

$SCAN#7

Hide Barcode End Chars: Scan the command barcode for hiding end characters.

$SCAN#8

Output Format for Hiding

To change the Scan Data Transmission Format for hiding characters, scan one of the following eight barcodes corresponding to the desired format.

Enable Hide Barcode Start Char:

$DATA#5

Enable Hide Barcode Middle Char:

$DATA#3

Enable Hide Barcode End Char:

$DATA#4

Procedures for Hiding Barcode Characters

Follow these steps to hide characters from the barcode's start, middle, or end:

1. Scan the appropriate command barcode: "Hide Barcode Start", "Hide Barcode Middle Start", "Hide Barcode Middle length", or "Hide Barcode End Chars".
2. Determine the hexadecimal value for the desired length. For example, to hide 4 characters, scan 04; to hide 12 characters, scan 0C.
3. Scan the two-digit hexadecimal value from the Numeric Bar Codes section.
4. Scan the output format barcode to enable or cancel the character hiding function.

Custom Prefix and Suffix

Up to 20 prefixes and 20 suffixes can be added to scan data for editing purposes. To set these values, scan a two-digit hexadecimal number (represented by two barcodes) corresponding to ASCII values. Refer to Table 1 and the Numeric Bar Codes section for details.

Adding a Prefix or Suffix

1. Scan the command barcode: "Add Prefix" or "Add Suffix".
2. Find the prefix or suffix hexadecimal value in the ASCII Chart.
3. Scan the two-digit hexadecimal value from the Numeric Bar Codes.
4. Repeat steps 2 and 3 for each prefix or suffix you wish to add.
5. Scan the output format barcode to enable or disable prefix/suffix output.

Command Barcodes for Prefix/Suffix

Add Prefix:

$SCAN#2

Clear All Prefix:

$SCAN#4

Add Suffix:

$SCAN#1

Clear All Suffix:

$SCAN#3

Numeric Bar Codes

These barcodes represent hexadecimal values used for configuration.

Numeric Values 0-9:

$NO#0, $NO#1, $NO#2, $NO#3, $NO#4, $NO#5, $NO#6, $NO#7, $NO#8, $NO#9

Hexadecimal Values A-F:

$NO#A, $NO#B, $NO#C, $NO#D, $NO#E, $NO#F

Output Format Options

To change the Scan Data Transmission Format, scan one of the following barcodes:

Default Output Format:

$DATA#0

Enable Prefix Output:

$DATA#2

Enable Suffix Output:

$DATA#1

Example: Adding Normal Prefix and Suffix

To add prefixes "A" and "B", and suffix "!" to the barcode "123456789":

1. Scan the command barcode: "Add Prefix".
2. Check the ASCII Chart for the hex values of "A" (41H) and "B" (42H).
3. Scan the two-digit hex value for "A": $NO#4, $NO#1.
4. Scan the two-digit hex value for "B": $NO#4, $NO#2.
5. Scan the output format to enable prefix output: $DATA#2.
6. Scan the command barcode: "Add Suffix".
7. Check the ASCII Chart for the hex value of "!" (21H).
8. Scan the two-digit hex value for "!": $NO#2, $NO#1.
9. Scan the output format to enable suffix output: $DATA#1.
10. Scan the barcode "123456789". The output will be "AB123456789!".

Example: Adding Combination Key Suffix

To add the combination key "Ctrl+P" as a suffix to the barcode "123456789":

1. Scan the command barcode: "Add Suffix".
2. Check the ASCII Chart for the hex values of "Ctrl+P": 97 (Ctrl), 50 (P). Note: The OCR shows "9" "7" "5" "0" which seems to be a typo or misinterpretation. Based on standard ASCII for Ctrl+P, it's usually represented by control codes. The table shows Ctrl as 97H. Let's assume the document intends to use specific codes for key combinations. The provided OCR for page 6 says "Ctrl+P - "9" "7" "5" "0"". I will use these values as provided by OCR.
3. Scan the four-digit hex value from the Numeric Bar Codes: $NO#9, $NO#7, $NO#5, $NO#0.
4. Scan the output format to enable suffix output: $DATA#1.
5. Scan "Keyboard Ctrl Combination Key" (This implies a specific barcode for this function, but it's not explicitly shown as a command barcode in the text. It might be a general instruction to use a specific key combination on the scanner itself or a separate configuration step not detailed here. Given the context, it's likely referring to a specific barcode that enables the interpretation of subsequent key combination inputs. Since no such barcode is explicitly listed with a code, I will describe it as a step.)
6. Scan the barcode "123456789". The output will be "123456789" followed by the "Ctrl+P" sequence. (Testing on Excel is mentioned).
