User Interfaces
TM120 – Rev. 1.1

DM240 will overwrite the PCR Value in appropriate
packets to compensate for any Null Packets, which have
been inserted into the data stream.
The Transmit Clock (SCT) supplied by the DM240XR is always Output.
Normally, this clock is used to clock the data out of the data source and
then return it to the SCTE input. The DM240XR is then set to SCTE mode
eliminating any possible clock skew. Alternately, the data source can
generate the SCTE clock internally and the SCT signal can be ignored. If
SCT mode is selected, the Modulator data clock will not be locked to the
incoming data stream. This mode is NOT recommended except for
testing or fault backup.
4.2.3.2 Ethernet Interface (J1)
The PIIC Ethernet Data Interface (EDI) is a full duplex 100/1000 Base-T supported by an RJ45
connector. The EDI supports the input of generic UDP packets or Pro–MPEG COP3 formatted
packets. With the Pro-MPEG input, a powerful video-specific packet-based forward error
correction (FEC) algorithm is also available providing a cost-effective solution for error recovery in
video streams transported over public or private IP networks.
Ethernet Data Interface, Additional Menus
When the Ethernet Data Interface is installed, it will add new menus for control and status
monitoring. It is recommended that all Ethernet parameters be selected prior to placing the unit
into the network.
INTERFACE MENU - The following new items are available under the Interface menu
INTERFACE TYPE:
{ETHERNET}
When the slot with GigEth card is active, the interface
type will be Ethernet.
TERR FRAMING:
{DVB 188}
When the Ethernet Data Interface is installed, the
terrestrial framing is fixed DVB 188 and cannot be
changed.
TERR ETHERNET:
Menu comes up when GigEth card is installed.
TERR MAC ADDR:
{0123456789AB}
This menu displays the MAC address of the Ethernet
Data Interface card. Entering any non-zero value in this
field will cause the EDI to use the entered value as its
MAC address. Entering a value of all zeros will cause
the Ethernet Data Interface to revert back to its original
MAC address.
