Screen Service Transmitter SDT 201 ARK6
This connector is designed to communicate with transmitters using the DVB-T2 and Digital Repeater modes.
About
The connector communicates with the device using SNMP, to change its configuration and to monitor its channel, power and modulation parameters.

Installation and configuration
Creation
SNMP main connection
This connector uses a Simple Network Management Protocol (SNMP) connection and requires the following input during element creation:
SNMP CONNECTION:
- IP address/host: The polling IP of the device.
- Device address: Not required.
SNMP Settings:
- Port number: The port of the connected device, by default 161.
- Get community string: The community string used when reading values from the device, by default e.g., public.
- Set community string: The community string used when setting values on the device, by default e.g., private.
Usage
Home Page
This page contains general parameters that can be used to configure the device (Transmission Mode, Station Identifier, LCD Stand-by, Reset, and Modes Management).
Input Section
On this page, you can monitor the Word Rate, Input Bitrate, Filtered Bitrate, etc. of the transmitter interfaces.
frontend
This page displays all the parameters related to the frontend. You can check the status using parameters such as Carrier Offset, SNR, Signal Quality or Bitrate.
Pre-signaling parameters are also monitored, such as Input Stream Type, FFT Size, Modulation Scheme, Code Rate, etc.
Finally, the page also displays the configuration, as well as post-configuration parameters like FEF Type.
DVB-T2 Processing
This page allows you to manage important parameters related to the DVB-T2: Input Selection or Output Channel and Power.
You can also enable the Input Autoswitch and check the associated parameters (Primary to Secondary Switch Counter, ...).
DVB-T2 Modulation Section
On this page, you can set DVB-T2 modulation parameters such as Parameters Source or T2-MI PID Mode.
The Pre Signaling and Post Configuration can be changed via page buttons.
If you change parameters, the new configuration is automatically updated in the T2-MI mode. However, in case the change is not taken into account, you can press the Load Configuration button.
DVB-T2 Measure
This section provides measuring results of the modulation parameters configured in the preceding pages.
Echo Settings
On this page, you can manage the alarm thresholds, using the parameters Signal Quality Thresholds and MER Threshold. "FE" and "Measure" thresholds can also be configured on this page.
Echo Canceller
On this page, you can manage the Threshold Fold Back parameters and monitor the Input and Residual Output Powers, among others.
The Clear Coefficient button allows you to reset the Echo Correction coefficients.
Output Section
On this page, you can select the Frequency Reference, view the Optocouplers and Relays status, change the Output Power, monitor the Temperatures, FANs Speeds, Power Supplies (PS) Voltages and Currents, and manage Reflex Power parameters.
You can also do Resets and adapt Forward Power and Temperatures Alarming Thresholds when necessary. The Reset button is used to reset the amplifier stage when it is switched off due to a Reflex Power High alarm.
Network Status
This page displays information and statistics about the network interfaces of the device (IP address, MAC address, Network Speed, Entered Packets count, ...).
Network Tx
On this page, you can select the Source Port, enable/disable the ARP Keep Alive option, and modify several parameters related to the Output Channels (Destination IP, Destination Port, Protocol, Source Clock Reference).
Network Rx
This page allows you to enable or disable IGMP and to modify the input configuration IP address, Local Port or Source Clock Reference.
SNMP Management Section
This page displays the SNMP Management Addresses, as well the associated Mode, Delay and Delay Status information.
GPS Section
This page displays all GPS information (Latitude, Longitude, UTC Date, ...).
It also allows you to adjust the GPS Frequency and Time Source (for synchronization), check the OCXO Status, manage the Holdover Mode and configure the NTP Server IP Address.
Alarms Section
This page displays generated alarms. It is possible to enable the sending of alarm traps to one or more Alarm Trap Managers. You can also configure whether the alarms will be displayed on the LCD screen, on the Java Alarm Page Icon, etc.
Events Section
This page displays a table with generated events.
Webpage
This page displays the web interface of the device. However, note that the client machine has to be able to access the device, as otherwise it will not be possible to open the web interface.
