The Status LED also works in

factory default configuration,
push in and hold the Reset
button. When the Status LED
starts flashing slowly, and
before it starts flashing
rapidly, release the button.
The SDS then restarts
automatically.
and 2. To restore the SDS to the
factory default firmware
revision, push in and hold the
Reset button. When the Status
LED changes from a slow flash
to a rapid flash, release the
button. The SDS then restarts
automatically.

Meaning
On steady = connected to network
On steady for Wi-Fi SDS units:
Infrastructure = SDS is
associated with Access Point
Ad hoc = SDS has found
device to communicate with
Off = 10 Mbps network connection
established if Link LED is on
On steady = 100 Mbps network
connection established
Red = RS-232 connection
Green = RS-422/485 connection
Blinking = data activity
On = SDS is up and running
If the Reset button is held during
the first 10 seconds of bootup, the
Status LED flashes at a rate of 1
flash every 2 seconds for 10
seconds. If the button is released
during this time period, the
configuration is reset to factory
defaults.
If the Reset button is held past the
first 10 seconds of bootup, the LED
flashes faster at a rate of 1 flash
every second for 10 seconds. If the
button is released during this time
period, the SDS is reset back to the
factory default firmware revision.
