Direct Mode- UHF Interface
This interface allows the Host Application to perform specific operations pertaining to UHF type tags.
These commands override the printer database as they interface directly to the tag module.
Knowledge of UHF protocols and their operation is required.
STX KuW
Write Data to RFID Tag
This command instructs the RFID device to write data to the tag. It is expected that the tag
transponder will be within the read / write distance of the RFID programming device; otherwise,
a warning will occur and a warning message (Read / Write Fail) will be displayed.
Syntax:
<STX>KuWabcc…c<CR>
a
- The number of attempts (1-9) to locate, erase, and program the
tag.
b
- Reserved. Should be 0.
Where:
cc…c
- Data to be encoded in the ASCII format. Must be sixteen
characters in length. The valid characters are 0-9, A-F.
Note: Must be 16 or 24 characters long.
Sample:
<STX>KuW10ABCDEF0102030405[CR]
The sample programs the data
<0xAB><0xCD><0xEF><0x01><0x02><0x03><0x04><0x05>
to the tag, attempting to
write one additional time if necessary.
STX KuR
Read Data from RFID Tag
This command instructs the RFID device to read data from the tag and then place that data into a
replaceable field. It is expected that the tag transponder is within the read / write distance of the
RFID programming device; otherwise, “Void” will be printed in the text or bar code label field(s).
Note: Data should be at least 16 or 24 characters in length.
Syntax:
<STX>KuRaa<CR>
Where:
aa
- Field number in which to place the data (must be 01, 02, 03, etc.)
matching the order of Label Formatting command, U.
Note: The 00 value will send the unique tag ID to the host with no
printing.
Sample:
<STX>L
D11
1911A1801000100 xxxxxxxxxxxxxxxx
U
1A31050002000200 xxxxxxxxxxxxxxxx
U
X
<STX>KuR01
<STX>Kur02
<STX>G
The sample creates a replaceable text field (01) and bar code field (02) and then recalls the data
from the tag and places it into the specified fields.
