Enter the Terrestrial Interface type.
{DVB 188, DVB 204, DIRECPC, NONE}
Terrestrial Framing – Allows the user to choose framing
packet.
{NORMAL, INVERTED}
Allows the data to be used as is or to be inverted.
{SCTE, SCT}
Input Clock Source – Allows the user to choose between
an internal (SCT) and external (SCTE) clock sources.
{NORMAL, INVERTED}
Input Clock Polarity – Allows the user to use the input
clock signal as is or to invert it.
{"Status Only"}
When used with G.703, the user may choose between
an internal (SCT), external (SCTE), or no output clock
sources. All else provides status only.
{NORMAL, INVERTED}
Output Clock Polarity – Allows the user to use the output
clock signal as is or to invert it.
{Internal, External}
Reference Frequency Source – Allows the user to select
either an internal or external reference source.
External Reference Frequency:
Enter the External Reference Frequency in 8 kHz steps
from 1 MHz to 10 MHz.
{ON, OFF}
This selection is available only when the Advanced ASI
Interface Type is selected. When set to "On," the
DM240 will overwrite the PCR Value in appropriate
packets to compensate for any Null Packets, which have
been inserted into the data stream.
