The Gallagher T20 Reader
The Gallagher T20 Reader is a smart card proximity reader. The reader can be
installed as either an entry reader or an exit reader.
The reader can be mounted on a rectangular 50 mm x 75 mm (2" x 3") flush box, BS
4662 British Standard square flush box, or any solid flat surface.
The Mifare reader reads: Mifare DESFire EV1, Mifare Plus and Mifare Classic cards.
The Multi Tech reader reads: Mifare DESFire EV1, Mifare Plus, Mifare Classic and 125
KHz cards.
The reader sends information to the Gallagher Controller and acts upon information
sent from the Gallagher Controller. The reader itself does not make any access
decisions.
The reader uses the Cardax IV communications protocol to communicate with the
Gallagher Controller. Refer to the "Connections" topic later in this note, for details
regarding Cardax IV Reader connections.
