REFERENCES13955.1.2 ACK/NACK ProtocolDRAGON™ D ReadersThis parameter sets a transmission protocol in which the Host responds to the readerafter every code transmitted. The Host sends an ACK character (06 HEX) in the caseof good reception or the NACK character (15 HEX) requesting re-transmission, in thecase of bad reception.DRAGON D HostACK or NACKdatacableACK/NACK enabledIf the reader does not receive an ACK or NACK, transmission is ended after the RXTimeout, see par. 5.1.4.Selection of the ACK/NACK protocol temporarily disables FIFO buffering, see par.5.1.3.DRAGON™ M ReadersThe transmission protocol takes place between reader, cradle and Host. The readerpasses its data (code read) to the cradle which sends it to the Host. Themanagement of responses (from Host or cradle) depends on the Transmission Modeparameter, see par. 5.8.3.In the following descriptions the completed transmission is indicated by the BeeperControl for Radio Response parameter with its default setting to Normal, see par.5.8.4.When ACK/NACK is disabled (in One-Way tx mode), there is no control from cradleto Host transmission, the reader responds with the good reception tone.OM-DRAGON™ HostdatacableDRAGON MdataTransmission Mode = One-Waygood RXbeepACK/NACK disabled
