Set EAS

The set command will activate the function if the EAS feature is not locked nor protected by the configuration

password.

If the EAS mode is locked, the Set EAS command will be ignored, and the ST25TV02K/512 respond with an error.

When the EAS mode is not locked:

•

If the EAS mode is not protected by password, the Set EAS command will set the EAS mode.

•

If the EAS mode is password protected, the configuration password has to be first transmitted with the

PRESENT PASSWORD command. Then the set EAS command can be executed, and will set the EAS

mode.

•

If the EAS mode is password protected, but the PRESENT PASSWORD has not been transmitted before or

not successful, the set EAS command is not executed and the ST25TV02K/512 respond with an error.
