JA command Example 2:
• Mode 4 is the current application mode.
• The host executes the following FX command to disable
compression:
HEX 30 46 58
CHAR 0 F X
• The host executes a JA command, specifying Mode 3:
HEX 33 4A 41
CHAR 3 J A
When Mode 3 is selected from the scanner operator control panel,
all of the features of Mode 4 that were available prior to the
execution of the FX command described above remain
unchanged, except compression (which is now disabled); these
values are assigned to Mode 3.
The Mode 3 definition has been overwritten by execution of this
command. When the operator selects Mode 4 again, all of the
features of Mode 4 that were available prior to the execution of
the FX command described above remain unchanged.
