8.6.4 Beeper Control for Radio Response

For M-Series readers, the data entry good read tone normally results in two beeps; the first indicates that the
reader has decoded the code, the second indicates whether EXOM-Dragon has received the data.

This can be changed according to the following selections:

Normal: both good decode and good reception are signalde (two beeps).

Only good decode: only the first beep indicating a good read is signaled.

Only good reception: only the second beep indicating a good reception is signaled.

Off: neither good read nor good reception beeps are signaled.

For all configurations, any transmission errors will always be signaled

8.6.5 Single Store

When single store mode is enabled, if the EX-Dragon-M fails to transmit a code to the cradle, it enters a special
operating mode that prevents the user from reading barcodes. When such operating mode is entered, the
trigger no longer enables barcode reading but is used to retry transmission itself for the number of attempts
selected in configuration. Once the transmission is successful the reader returns to the standard mode. If
transmission is not successful after the number of configured attempts, the code is discarded.

Single store may be useful if you often read codes at the limit of the coverage area and there is a chance that
code transmission can fail. In such case single store allows you to move to a more favorable position or location
( i. E. closer to the cradle) to retry transmission without the necessity of re-reading the code since it is already
stored in the reader.

Conversely, if single store is disabled, and the user wants to retry transmission, the code must be read again,
and therefore the attempt must be made from basically the same location. If the user gives up, he does not
know if the transaction was successful. (Actually the transmission could have been successful but the cradle
may habe been unable to acknowledge the message). There are applications in which there is no risk of
transmission failure. In such cases it may be better to disable single store so that the user perceives a more
consistent behavior of the trigger in that it always corresponds to code reading.

8.6.6 Batch Mode

This Operating Mode allows storing read codes in the internal gun memory. The stored codes are transmitted to
the base station at a later time according to the type of batch mode selected.

Batch mode can be enabled either manually (normal batch mode) of automatically.

Normal batch mode temporarily suspends radio communication between gun and base station allowing codes
to be stored in the gun on a FIFO basis. This can be useful for example, if codes must be read from a location
where there is no radio network. Upon returning to the system working area, this mode requires reading the

barcodes to successively transmit the list of stored codes to the base

station. The FIFO management assures that the first code read will be the first code to be transmitted to the
base station.

The

barcode allows canceling all barcode data stored in the gun.

Automatic batch mode allows code to be stored in the gun on a FIFO basis whenever the gun is out of radio
range. In this case radio communication is not suspended and transmission is attempted after each code read.
If transmission cannot be successfully completed, then the code is added to the list. When the gun returns in
range, transmission of the codes to the base station resumes automatically, according to the selected
communication protocol upon simply pressing and releasing the trigger or by successfully reading a new code.

Each code is listed on the gun display together with its identifying position number and its total number of
characters. The three keys under the display have the following function in batch mode:
