Change between the SPP and the HID
You may make the scanner change between the SPP and the HID.
For example, if your scanner operates currently in the HID profile and you want to
change the existing profile of the scanner to SPP, then scan the SPP Device
barcode as shown below:
SPP Device
To determine whether your scanner’s profile is successfully changed, press the
Page button on the cradle; your scanner will have 2 short beeps when you press the
Page button.
For example, if your scanner operates currently in the SPP and you want to change
the existing profile of the scanner to the HID profile, then scan the HID Device
barcode as shown below:
HID Device
Whenever the scanner enters the HID profile, you must pair the scanner with your
PC following step 3 through step 8 at the section called “Human Interface Device
(HID) Profile”.
Note: When you successfully enter the profile, the address is kept in the scanner. If
you want to make the scanner completely disconnect, scan the Delete
Address barcode, as shown below.
Delete BT Address
Memory Buffer Setting
The collected data can be sent back to a host computer one by one via the WPAN
connection to the scanner being 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 Buffer 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 Buffer 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 provides you with 2 memory mode settings: Batch Mode and Inventory
