The COFDM module is equipped with an electrical connector (RJ45) marked “control” that is
not in use. It is not required to configure the IP address or connect the port to the IP network.
3.3.5 DVB-T/T2 Input
Each DVB-T/T2 input module has one or four 75Ω F connector. For the module having one
input connector, the input is distributed to four tuners internally, so each module can receive
four independent frequencies. For the module with 4 inputs, each input is directly connected to
a tuner. The maximum input level is -10dBm (both modules). The recommended input level is
between -20dBm and -40dBm (optimal lever will depend on modulation used).
3.3.6 QAM A/C Input
Each QAM input module has one 75Ω F connector. The input is distributed to four tuners
internally, so each module can receive four independent frequencies. The maximum input level
is -15dBm. The recommended input level is between -30dBm and -50dBm.
One ASI output port is available for monitoring. Any of the four QAM inputs can be copied to the
ASI output without affecting the services in use. The ASI connector is a 75Ω BNC connector.
The QAM module is equipped with an electrical connector (RJ45) marked “control” that is not in
use. It is not required to configure the IP address or connect the port to the IP network.
3.3.7 8VSB Input
Each 8VSB input module has four independent 75Ω F connectors.
One ASI output port is available for monitoring. Any of the four 8VSB inputs can be copied to
the ASI output without affecting the services in use. The ASI connector is a 75Ω BNC
connector.
The 8VSB module is equipped with an electrical connector (RJ45) marked “control” that is not in
use. It is not required to configure the IP address or connect the port to the IP network.
3.3.8 QAM-B Input
Each QAM-B input module has four independent 75Ω F connectors.
One ASI output port is available for monitoring. Any of the four QAM-B inputs can be copied to
the ASI output without affecting the services in use. The ASI connector is a 75Ω BNC
connector.
The 8VSB module is equipped with an electrical connector (RJ45) marked “control” that is not in
use. It is not required to configure the IP address or connect the port to the IP network.
3.3.9 SDI Encoder
The SDI Encoder module has 4 BNC inputs that vary in functionality depending on the mode.
These functions are as follows:
• SD Encoder – Port A, B, C and D are in SDI mode and link to the 4 corresponding
internal encoder ports
• HD Encoder – Port A and B are in HD-SDI mode and link to the 2 corresponding
internal encoder ports
