Chapter1-Overview
ProductIntroduction
The EN20 is a High and Standard definition MPEG-2 or H.264 encoder supporting
ATSC and DVB tables through ASI and IP transport streams. The EN20 is capable of
supporting up to 2 encoder modules and can be ordered with optional QAM modulation for
distribution applications.
It inherits Adtec’s broadcast quality compression, advanced feature set, service
performance and reliability in the new dense two-channel platform targeted towards
broadcasters, cable and IP compression applications.
The device automatically detects video and audio from two sources (combination of
HD and SD acceptable), encodes, multiplexes and sends them back out as one combined TS
via IP, ASI or optional QAM. Closed captioning and support for Emergency Alert (EAS)
triggering are standard.

FrontPanel
The Function Buttons and Directional Keypad of the EN-20 are used to configure and
monitor the signal input and output of the device.
Panel Diagram
Front Panel LCD
There are 3 states of the front panel LCD.
1) Encoding State: When in normal encoding mode, the LCD will display the following
information. Since there are can be 2 encoders in the product, you can view the status of
each by pressing the down button to toggle between 1 & 2.
2) Video Loss State: When video is not detected on the selected input, the LCD will display
the following information.
3) Disabled Product State: When the product is in a disabled state, the LCD will relay the
following information. This state is generally only used when a factory restore is performed.
If that is the case, note that all of the configurations have been returned to factory defaults
including Network configurations. To reapply network configurations simply press the Down
arrow when in this state to navigate through the network menu. In the event that you see a
similar message followed by a phone number, this indicates that the Temporary keys on the
device have expired and you should contact your sales representative.
