JA — Define mode
The JA command alters the preprogrammed application mode by
storing the current operating mode in its place. After the current
operating mode has been stored as one of the 18 application
modes, it can be selected in one of two ways: the operator can
select it by entering function code F01 on the scanner operator
control panel; or the scanner-unique Set Mode (HA) command
may be used.

Data Field Description Value(s)
mode mode number 1–18
JA command Example 1:
• 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 4:
HEX 34 4A 41
CHAR 4 J A
When Mode 4 is selected from the scanner operator control panel,
all of the features of the mode that were available prior to the
execution of the FX command described above remain
unchanged, except compression (which is now disabled).
If the host had not executed the JA command following the FX
command, when the operator selects Mode 4 from the operator
control panel, ALL features of the mode that were available prior
to the execution of the FX command described above would
remain unchanged, including compression.
