4-2 Packet Reference Manual
Applying Options to the RFID Data Field
All the normal field options (copy, merge, pad, increment, etc.) can be applied to the RFID Data
Field. However, certain restrictions may apply.
♦ To copy, merge, pad, or increment data in the RFID Data Field, the
copied/merged/padded/incremented data must be in ASCII Hex format.
♦ When incrementing an RFID Data Field or EPC data, the data increments as follows: 0 to F
(0123456789ABCDEF), then back to 0.
♦ When incrementing the RFID Data Field or EPC data, the only valid value to increment is by
one.
♦ If Option 60 (Increment Field) contains the character D to decrement, it is ignored and the
field is instead incremented by one.
♦ Use caution when incrementing an RFID field if data is coming directly from your host because
the field must be incremented in ASCII Hex.
Using Option 1 (Fixed Data)
Fixed data is information (a company name or store number) you want to print on all labels. You
can define fixed characters for an entire field or for part of a field.
Syntax R,1,"fixed char" |
R1. R Option Header.
R2. 1 Option 1.
R3. “fixed char” Characters to insert. Enclose in quotation marks. If you are defining
fixed characters for part of a field, place underscores(_) in non-fixed
positions. Any spaces in the phrase are fixed characters. Range: 0 to
2710.
Note: Underscore characters are stripped out and the data is compressed if no
data is supplied by the batch and the field length is variable.
Example R,1,"_ _ _%$_ _ _ _ _" |
Uses fixed characters (%$) in positions 4 and 5. The other positions are variable.
Example R,1,"MONARCH" |
“MONARCH” appears as a fixed field in this example.
To fill in the non-fixed portion of the field, see “Defining Batch Data Fields” in Chapter 6. As an
alternative, you can apply Option 4 to copy data into the non-fixed character positions.
