After powering up, the DDK-3000 Video Encoder performs a self-diagnostic to detect any hardware
defects. The following table lists the normal LED patterns. In case of any fatal error, the LED will blink in
a pattern other than those below.
Condition

Other patterns
Reset and restore
There is a button recessed in the pinhole beside the Ethernet socket. It is used to reset the system or
restore the factory default settings. Resetting the encoder will return the system back to its original state.
If the system still has problems after reset, restore the factory settings and install again.
RESET
Insert probe to depress the button.
RESTORE
1. Insert probe to depress and hold the button continuously.
2. Wait for self-diagnostic to run twice (10 sec. )
3. Withdraw the probe as soon as the second self-diagnostic starts
Restoring the factory defaults will
erase any previous settings. Reset or
restore the system after power on.
