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 2MB 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.

MS842 features 2 memory mode settings: Batch Mode and Inventory Mode

Note: The 2MB of memory buffer in the scanner can hold as approximately many

as 1290555 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. 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.

Batch Mode

If you do not output the barcode data, the barcode data is always kept in the

memory buffer. When being outputted, the 1D data is erased from the memory

buffer. However, when being outputted, the 2D data is still kept in the memory

buffer, and thus if you want to erase the 2D data from the memory buffer, scan the

following barcodes in the order.

When the scanner is out of batch mode, the data will be temporarily stored in the

RAM, which has 4K storage capacities; however, in the inventory mode, the data

will be stored in the flash, which has 2MB storage capacities.
