Medio S004 EVM
7 Stand-alone Mode
Stand-alone Mode is designed to use the reader without using any command set. While in Stand-
alone mode, the reader only performs tag reading operations.
The reader sends the tag ID to the Host System using ASCII protocol via the Reader-to-Host
interface.
ASCII protocol is used in order to provide hexadecimal data that can be read by a variety of
terminal programs (e.g. Microsoft
®
HyperTerminal).
