“nnnn” is the subscription number in the example. The receiver will respond with
“subscription accepted.”
Auto-Dif is now loaded as the current application and is ready for use.
3. Finding out the current application
After the $JAPP,OTHER or $JAPP,1 or $JAPP,2 command is used to switch to one of
the two installed applications, you might use the $JT command to find out which of the
two applications is the current or “active” one.

3.3.2.3 Interpreting Subscription Date Codes
A date code is a 4-digit number that can be used to gain a quick understanding of what
subscription codes were applied to the receiver. There are two commands that provide the date
code of the receiver. This section provides information on interpreting the $JI and $JK
subscription date codes. An example of the $JI and $JK subscription date codes is listed below.
The date code is in bold and underlined text.
$>JI,12838,1,7,26022003,01/01/1900,01/01/
3000
,6.8Hx,38
$>JK,01/01/
3000
,0,(1,2 or no number)
The field to the right of the date code in the $JK response (“0” in this example) corresponds to
the hexadecimal equivalent to the last two digits of the date code.
