DRAGON™ D131/M1315Conversely, if single store is disabled, and the user wants to retry transmission, thecode must be read again, and therefore the attempt must be made from basically thesame location. If the user gives up, he does not know if the transaction wassuccessful. (Actually the transmission could have been successful but the cradle mayhave been unable to acknowledge the message). There are applications in whichthere is no risk of transmission failure. In such cases it may be better to disablesingle store so that the user perceives a more consistent behavior of the trigger inthat it always corresponds to code reading.5.8.6 Batch ModeThis Operating Mode allows storing read codes in the internal gun RAM memory.The stored codes are transmitted to the base station at a later time according to thetype of batch mode selected.Batch mode can be enabled either manually (normal batch mode) or automatically.Normal batch mode temporarily suspends radio communication between gun andbase station allowing codes to be stored in the gun on a FIFO basis. This can beuseful for example, if codes must be read from a location where there is no radionetwork. Upon returning to the system working area, this mode requires reading theStart Normal Batch Transmission barcode to successively transmit the list ofstored codes to the base station. The FIFO management assures that the first coderead will be the first code to be transmitted to the base station.The Delete Batch Data barcode allows canceling all barcode data stored in the gun.Automatic batch mode allows codes to be stored in the gun on a FIFO basiswhenever the gun is out of radio range. In this case radio communication is notsuspended and transmission is attempted after each code read. If transmissioncannot be successfully completed, then the code is added to the list. When the gunreturns in range, transmission of the codes to the base station resumesautomatically, according to the selected communication protocol, upon simplypressing and releasing the trigger or by successfully reading a new code.Each code is listed on the gun display together with its identifying position numberand its total number of characters. The three keys under the display have thefollowing function in batch mode:Key Function▲ (left) Key Scroll up in listENTER (center) Key Delete highlighted code▼ (right) Key Scroll down in list152
