Blinking at long intervals: The
device successfully registers
with the ECC800-Pro and the
software runs properly (the
indicator blinks at 0.5 Hz, on
for 1s and then
o for 1s).
Blinking at short intervals: The
communication is disconnected
or the device fails to register
with the ECC800-Pro (the
indicator blinks at 4 Hz, on for
0.125s and then
o for 0.125s).
Blinking: The indicator blinks at
super short intervals for 0.5s
(blinking at 10 Hz, on for 0.05s
and then
o for 0.05s) and
then turns
o for 0.5s. The
cycle lasts for 10s.
Check the power supply.
If the RUN indicator blinks
