User`s manual
844A is driven by an easy-to-use control program with pull-
down menu, hot keys and on-line help. Selecting of device is 
performed by its class, by manufacturer or simply by typing a 
fragment of vendor name and/or part number. 
Standard device-related commands (read, blank check, 
program, verify, erase) are boosted by some test functions 
(insertion test, signature-byte check), and some special 
functions (autoincrement). 
All known data formats are supported. Automatic file format 
detection and conversion during load of file. 
The rich-featured autoincrement function enables to assign 
individual serial numbers to each programmed device - or 
simply increments a serial number, or the function enables to 
read serial numbers or any programmed device identification 
signatures from a file. 
The software also provides a many informations about 
programmed device. As a special, the drawing of all available 
packages are provided. The software provide also explanation 
of chip labeling (the meaning of prefixes and suffixes at the 
chips) for each supported chip. 
Various socket converters are available to handle device in 
PLCC, SOIC, SSOP, TSOP, TSSOP, TQFP, QFN (MLF) and 
other packages. 
Advanced design, including protection circuits, original brand 
components and careful manufacturing allows us to provide a
