ACG Identification Technologies AT Page 20
5.3.3.1 Unique device ID (00h-04h)
The unique device ID identifies a reader module. It is factory programmed and cannot
be changed.
5.3.3.2 Station ID (0Ah)
The station ID is used in binary mode to address a device in party line set up. The
station ID has the rage of 01h to FEh and can be freely set. The value 00h is
reserved for the bus master. All readers send a response to this device.
The broadcast message (FFh) forces all readers to response to the command.
Default value is 01h.
5.3.3.3 Protocol configuration (0Bh)
The PCON register specifies general behavior of the reader device.
Default value is 01h.

5.3.3.3.1 Auto start (default 1)
If set the reader device will start up in continuous read mode automatically. Auto start
has only effect in ASCII protocol mode.
5.3.3.3.2 Protocol (default 0)
If set the reader uses binary protocol mode. As default ASCII protocol is used. See
section binary protocol for further information on the binary protocol format.
5.3.3.3.3 Binary timeout (default 0)
If set the reader sets up a binary timeout internally. This bit should be enabled in
binary protocol mode to ensure correct framing.
5.3.3.3.4 Lock mode (default 0)
If set the reader locks itself to the first recognized tag type automatically. Other tag
types are not recognized. Only a reset or a change operation mode command
cancels the lock state.
5.3.3.3.5 LED (default 0)
If set the reader suppresses any LED activity. The user manages the state of the
LEDs.
