Show Raw

 button displays raw tag data on the 

Query page. Each entry shows Reader, 
protocol, antenna, and tag data.

 button stops the display of raw tag 

data. 

 

Clear Output

 button clears the data displayed. 

 

Query Once

 button initiates a single search 

cycle after clicking 

Start

Write Page 

Use the Write page to replace the EPC data that is 
encoded on a 915 MHz EPC Class 1 tag. 

 

Consider the following guidelines when writing to 
tags: 

  Always place a tag 0.3–0.6m (1–2ft) from the 

antenna when writing data. The tag may be 
damaged if it is too close to the antenna. 

  Only unlocked 915 MHz tags can be used. The 

write function is not supported for 13.56 MHz 
tag protocols. 

  The data to be written must be exactly 16 

hexadecimal characters (numerals from 0–9 
and letters from A–F). 

  Always place only one tag in the antenna’s 

field when writing. If multiple tags are present, 
they will all be encoded with the same EPC 
data. 

  Use the antenna connected to UHF1. 

To write data to a tag: 

1. Click 

the 

Write

 link on the navigation menu. 

The Write page appears. 

2.  In the top pane, type or paste the 16-character 

hexadecimal data to be written to the tag. 

3.  Highlight the hexadecimal data. 

4. Click 

the 

Make Update

 button. A query 

designed to write the highlighted data to the 
tag appears in the center pane. 

5.  Place the tag 0.3–0.6m (1–2ft) from the 

antenna connected to UHF1. 

Verify that no other tags are in the antenna’s 
field. 

6. Click 

the 

Submit Query

 button to write the 

data. If the write was successful, the new tag 
data appears in the bottom pane. 

To read data from a tag: 

1.  Display the Write page (click the Write link on 

the navigation menu).
