NOTE: The PE ID number displays as a scrolling
three-digit number. Each digit displays briefly
followed by a blank display (the LED is briefly off)
before the next digit displays. A dash (-) is displayed
before the three-number is repeated in the display.
For example, the PE ID 175 displays 1, then blank
display, then 7, then blank display, and then 5
followed by a dash before the PE ID number is
repeated. Similarly, the PE ID 7 displays as 007: 0,
blank, 0, blank, 7, followed by a dash.
