Programming a Tag
Note: You have the option of first placing at tag into the tag holder before issuing the
command or you can enter the command and place the tag into the tag holder within
10 seconds. If you are programming an AT5549 End-of-Train Tag, place the tag into
the programmer adapter (P/N 20-4118-001), with the tag’s reflective side up, before
sliding the tag into the tag holder. If you do not place the tag in the tag holder and
close the door within 10 seconds, the programmer will abort this command.
