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.

JA command Example 1:

 

 

 

 

 

 

 

 

Mode 4 is the current application mode.

 

 

 

 

 

 

The host executes the following FX command to disable

 

 

compression:

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

HEX

The host executes a JA command, specifying Mode 4:

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.
