The ASI input port has a green indicator LED, with the following states:
•LED off: ASI port is disabled.
•LED flashing once every 3 seconds: the ASI port is not locked to a signal (i.e., there is
no input signal).
•LED flashing once per second: the ASI port is locked to a signal.
The ASI output port has a green indicator LED, with the following states:
•LED off: ASI port is disabled.
•LED flashing multiple times per second: ASI port is transmitting packets.
The Video output ports share one green indicator LED, with the following states:
•LED off: the decoder is not currently decoding a stream. There may be a valid video
signal in the output, but it does not correspond to a decoded stream.
•LED flashing once per second: the decoder is currently outputting an SD stream on the
selected output ports.
•LED flashing multiple times per second: the decoder is currently outputting an HD
stream on the selected output ports.
The Reference Input port has one green indicator LED, with the following states:
•LED off: no reference signal is detected.
•LED flashing: reference signal present.
The Control and Streaming Ethernets port have two indicator LEDs, with the following states:
•Green LED:
oOff: No link
oOn: Link
•Yellow LED:
oOff: No activity (transmit and/or receive)
oFlashing: Port is currently transmitting and/or receiving
Front Panel Indicators
A similar set of indicators exist in the front panel of the unit. The layout is depicted below.

14
The front panel LED indicators are as follows:
•STAT: indicates the overall status of the unit.
oGreen: no active alarm
oRed: at least one critical alarm present
When powering up the unit, this LED will be red until the board starts operation. At that
point, it will turn green if there is no active alarm or stay red if there is at least one alarm.
•PWR: indicates that the power is OK.
oGreen: power OK
oOff: no power or insufficient voltage
•ASI In LED: behaves exactly the same as the ASI input rear I/O panel indicator.
•ASI Out LED: behaves exactly the same as the ASI output rear I/O panel indicator.
•VID LED: behaves exactly the same as the Video output rear I/O panel indicator.
•Ref In LED: this LED blinks when the decoder is receiving a genlock signal from the
chassis reference input.
•ETH and CTRL LEDs: indicate the status of the corresponding back panel Ethernet
connection.
oOff: no link
oOn: link OK, no activity
oBlinking: link OK, port is transmitting and/or receiving packets
Front Panel Default Switch
The front panel has a recessed switch that can be used to restore the unit to its defaults. Use a
pen or a small screwdriver to press this switch.
If the switch is pressed during normal operation, the control port IP address, mask and gateway
are restored to the following factory default settings:
•IP Address: 192.168.1.30

15
•Subnet Mask: 255.255.255.0
•Gateway: 192.168.1.1
The STAT front panel indicator will change colors for about 3 seconds to acknowledge the
change. Note that this operation may glitch the video.
If you press and hold this switch when the unit is powered off, and then power up the unit while
holding the switch, the following actions will be performed:
•The control IP address, mask and gateway are reset to the factory defaults as described
above.
•The unit configuration is cleared.
•The unit reverts to the factory-installed firmware.
As before, the STAT LED will temporarily change color to acknowledge the command. When it
changes color, you can release the switch. You can use this feature in the unlikely event of a
corrupted firmware upgrade or a corrupted configuration.
