Interpreting LED Indicators
LED indicators on the receiver board can be used
for diagnostic purposes. During the power-on self-
test, all LEDs flash simultaneously to test their
function, then they light in sequence to indicate the
progress of the power on self-test. Figure 5 shows
the location of the status LEDs.

•
DS1 (red) is the alarm indicator.
•
DS2 (green) is the mode/power/heartbeat
indicator, which shows that the board is
powered and what mode the system is in
(Normal/Hidden Tag/Service).

•
DS3 (red) is the frequency rejection indicator. If
this LED is lit, the pedestal has detected an out-
of-frequency label, such as a deactivated or
wounded label, in the vicinity.
of-frequency label, such as a deactivated or
wounded label, in the vicinity.
•
DS4 (red) is unused.
•
DS5 (yellow) is the validation/system error
indicator. This LED flashes in a coded
sequence whenever the board fails the power
on self test, or run-time diagnostic tests, or
when a serious failure interrupt occurs. To
indicate an error code, the DS5 error LED on
the receiver board will flash a number of times,
pause, then flash again a number of times. For
example: DS5 flashing three times, pausing,
then flashing two times indicates error code 32.
Error codes are listed in Table 3.
