• Multicast IP – Enter the IP address for the Multicast of the TAP message that is sent out by
this CDD‐880 to all of the associated CDM‐840 Remote Routers in that group.
• Group ID (0‐255) – Assigning a unique Group ID number to this CDD‐880 (i.e., the HCC) and
its associated CDM‐840 Remote Routers defines the group of equipment that will respond
to the output of the controller. Enter the Group ID number for the CDD‐880.
While “0” is an acceptable designation, the preferred, practical range is 1‐255.
• Guard Band – This is the Amount of Transmit Off time, in milliseconds, between slots to
prevent signal overlap.
• Preamble (read‐only) – This value identifies the preamble length in VersaFEC frames.
• Data Slot Size (read‐only) – This value identifies Minimum number of Versa FEC blocks in a
data slot.
• Slots in Frame – Assign the allowable total number of slots for each frame. When assigned
slots are needed, they are taken from this pool.
• Switch Rate – Enter the initial Data Rate at which remotes are switched to dSCPC.
• Cycle Length (read‐only) – This value identifies the total cycle length, in milliseconds, of the
TAP message.
• LNB LO Frequency – Assign the LNB LO value, used to send RF frequency values in TAP
messages. Resolution = 100Hz.
• Satellite Frequency Conversion – Assign the correct Satellite Frequency Conversion value,
in MHz, for this hub unit based on the RF equipment used at this site.
