Memory Buffer Setting

The collected data can be sent back to a host computer one by one via the WPAN

connection as the scanner is set to the Batch Mode, or can be stored in the flash

memory of the scanner being set to the Inventory Mode.

By default, the Batch Mode is enabled for use when the scanner is out of range.

Upon reading a barcode successfully within range, the scanner responds with one

short beep (high tone) and its LED indicator becomes solid green and goes off

quickly. However, the host computer may not receive the data immediately if

getting out of range. With the 4 KB transmit buffer, the scanner can ignore the

transmission status and keep on reading barcodes until the buffer is full.

When the Batch Mode is enabled and the scanner is out of range, the scanner will

respond with two short beeps, high-low tone, upon reading a barcode successfully.

When the memory buffer is full, the scanner will respond with one long beep (low

tone) and its LED indicator will become solid red and go off quickly. You are

advised to get back to range.

MS840 features 2 memory mode settings: Batch Mode and Inventory Mode

Note: The 4 KB of memory buffer in the scanner can hold as many as 256 scans

based on EAN-13 barcodes. Data will be cleared out once the scanner is not

powered!

Batch Mode

Batch Mode is the default setting. To set the scanner to the Batch Mode, scan the

following barcodes in the order:

Enter Group 6

In the Batch Mode, once you scan a barcode by using a scanner wirelessly

connecting to the cradle (Cradle Mode) or a host PC (Cradle-less Mode) in a

specified range, the scanner sends out the data. When the scanner is out of range

of the cradle or the host and keeps trying to re-connect, the scanner will keep the

data in its memory buffer until the buffer is full; when the scanner is again in range

of the cradle or the host, the scanner will sent out the data that it has in the memory

buffer . When the buffer is full and the scanner is out of range, the scanner will

respond with one long beep (low tone) and its LED indicator will become solid red

and go off quickly. You are advised to get back to range.

Inventory Mode

Inventory Mode is the mode in which the scanner keeps the scanned data in its

memory buffer but not send out the data on the host automatically; you should scan

Read Buffer barcode to order the scanner sent out the memorized data to the Host.

To set the scanner to the Inventory Mode, scan the following barcodes in the order:

Exit

Enter Group 6
