Innovator CU0TD-1/CU0RD-1 – CU4TD/CU4RD 8VSB ATSC Modulator
ATSC Transmitter/Regenerative Translator
Instruction Manual, Rev. 2 46
The available parameters in MFN Mode are:
Item Selection
MH Enable OFF, ON
If this parameter is set to ON, ATSC-MH waveform
support will be enabled.
SFN OFF, ON
If this parameter is set to ON, the modulator will operate
in SFN mode and a number of additional parameters can
be edited by the user.
Table 8: MFN Transmission Parameters
When the modulator is used in conjunction with a UBS DTx Adapter, the user must
configure the modulator’s Transmitter ID (tx_address) correctly, so that the TCP
command information used to address the individual modulator (transmitter) is
extracted.
The Transmitter ID is a 12-bit unsigned integer, with a user configurable range of 0 to
4095. The Transmitter ID’s decimal value is equal to the DTx Adapter’s three character
hexadecimal string, which is determined by the DTx Adapter’s tx_group_ number and tx
id.
For example, a tx_group_number of “AB” and a tx id of “9”, would generate a 3
character hexadecimal string of “AB9”. In this case, the user must enter a Transmitter
ID of 2745. A tx_group_number of “DE” and a tx id of “15”, would generate a 3
character hexadecimal string of “DEF”. In this case, the user must enter a Transmitter
ID of 3567.
