Datalogic Scanning Memor 用户手册

 

 
 
Access Point 
A device that provides transparent access between Ethernet wired networks 
and IEEE 802.11 interoperable radio-equipped mobile units. Hand-held mobile 
computers, PDAs or other devices equipped with radio cards, communicate with 
wired networks using Access Points (AP). The mobile unit (mobile computer) 
may roam among the APs in the same subnet while maintaining a continuous, 
seamless connection to the wired network. 
 
Barcode 
A pattern of variable-width bars and spaces which represents numeric or 
alphanumeric data in binary form. The general format of a barcode symbol 
consists of a leading margin, start character, data or message character, check 
character (if any), stop character, and trailing margin. Within this framework, 
each recognizable symbology uses its own unique format. 
 
Baud Rate 
A measure for data transmission speed. 
 
Bit 
Binary digit. One bit is the basic unit of binary information. Generally, eight 
consecutive bits compose one byte of data. The pattern of 0 and 1 values within 
the byte determines its meaning. 
 
Bluetooth® 
A standard radio technology using a proprietary protocol. The onboard 
Bluetooth

® module in the mobile computer is compatible with the 1.1 protocol. 

 
Byte 
On an addressable boundary, eight adjacent binary digits (0 and 1) combined in 
a pattern to represent a specific character or numeric value. Bits are numbered 
from the right, 0 through 7, with bit 0 the low-order bit. One byte in memory can 
be used to store one ASCII character. 
 
Decode 
To recognize a bar code symbology (e.g.,  Codabar, Code 128, Code 3 of 9, 
UPC/EAN, etc.) and analyze the content of the bar code scanned. 
 
EEPROM 
Electrically Erasable Programmable Read-Only Memory. An on-board non-
volatile memory chip. 
 
Flash Disk 
Non-volatile memory for storing application and configuration files.
