e*Tag® Host Preview

what is e tag host
What is e*Tag® Host?
  • A graphic user interface designed to demonstrate the commands and responses available in e*Tag® reader/writers.
  • e*Tag® Host helps systems integrators and software designers to evaluate the capabilities of e*Tag® RFID systems.

Click on “Version” to see reader information. This is also an easy way to confirm that you are communicating with the reader.


Select the “Tag-it” tab if you are working with original T.I. Tag-it transponders and your reader supports this mode.

wiegand mode
Wiegand Mode

Wiegand Communications is commonly used for security access control applications.

When placed in a Wiegand mode e*Tag® readers will automatically read any transponders that enter the field and transmit card data to a host.


Use the selector to choose the Wiegand mode you want. UID modes read only the unique factory data on the tag. Card Data mode reads encrypted data that has been written on certain blocks of the card.


When a reader is in a Wiegand UID mode, the unique identification number and the reader serial number are sent in ASCII format on the RS-485 lines and the unique identifier is sent in the selected Wiegand format on the Wiegand lines.

read write mode
Read / Write Mode

In the read/write mode, data can be read from the transponder and new data can be written on the transponder.

Read/write functions are used in a variety of Automatic Identification and Data Collection applications.

When you select any read/write operation the reader will be taken out of Wiegand mode.


Select “View One Block” to read the data on a single block.

Click on “GO” to execute the command once.


Select “Continuous” then click “Go” to repeat the command continuously. Click “Pause” to interrupt the continuous command.


Select “View Many Blocks” to see data on a group of blocks. Up to 32 blocks may be read at one time.

Enter the starting block and the number of blocks to be read


Select “Program One Block” to write data on a single block.

Enter the block to be written and the data in hexidecimal format.


Select “Lock One Block” to lock the data written on a block.

Once locked, this data cannot be changed or erased.


Select “Program AFI” to Choose an Application Field Identifier.

The AFI can be used as a filter to ignore any transponders that are not intended for use in your type of application.


Select “Program DSFID” to set a Developer Selected Field Identifier.

DFSID can be used to convey custom information specific to the application.


Go to “Configuration” and “DeBug Mode” to view all host interface dialog at the bottom of the screen.


Go to “Configuration”, “Address Reader” to designate the serial number of a specific reader you want to communicate with.

e tag host summary
e*Tag® Host Summary
  • e*Tag® Host has been designed to demonstrate the various functions of e*Tag® reader/writers. In Wiegand mode these readers automatically detect transponders and transmit data to a host in a binary format.

e*Tag® Host Summary
  • In read/write mode a host can obtain data from transponders as well as write new data on them. Data is sorted by blocks. Data can be permanent (locked) or changeable.

e*Tag® Host Summary
  • Application-specific software can be written to use e*Tag® in a variety of Automatic Identification and Data Collection environments.
  • An Application Program Interface (API) and an open communications protocol are provided with the e*Tag® development kits.
