Work Microwave DVB-S2 Modulator

This connector polls status parameters and allows you to edit the configuration of older Work Microwave Modulator DVB-S2 devices, similar to the connector Work Microwave Modulator DVBCID/DVB2SX.

The device is a DVB satellite modulator and includes a DVB-S/S2/S2X modulator with VHF-band (50 to 180 MHz) and/or L-band (950 to 2150 MHz) output. The unit consists of four main parts, a modulator module (DVB data in input and L-band modulated signal in output), an IF converter module (clock at VHF-band), a power supply and a front panel controller.

About

The device is accessed via SNMP. The agent within the device is fully SNMPv1-compatible and responds to GET, GETNEXT and SET commands. If SNMPv2 is used, the device will also respond using SNMPv2. Traps are always v1. Control over the device will depend on the access type of SNMP parameters available in the Management Information Base (MIB).

This connector is compatible with "FMB" software units (front panel firmware starts with FMB).

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.

SNMP Settings:

  • IP port: The IP port of the device.
  • Get community string: The community string used when reading values from the device, by default public.
  • Set community string: The community string used when setting values on the device, by default private.

Usage

Modulator Configuration

This page contains the parameters for the configuration of the modulator signal: Signal Output, TX Frequency, TX Level, Symbol Rate, Data Rate, MODCOD, Roll-off, Slope Compensation and Spectrum Inversion.

The Automatic Disabled Polling toggle button is also available on this page. If this button is set to enabled, the polling of the modulator configuration parameters will be automatically disabled when a "NO SUCH NAME" error is received.

In addition, the Video Stream Configuration page button provides access to the DVB-S2 FEC Frame Length, Short BCH Code, Pilots, VCM/BB Frame Mode, PL Scrambling, TX Test Mode, Data Input, SPI Synchronization, Frame Type, TX Clock Synchronization, MPEG2-TS Packet Stuffing, Null Packet Deletion and Still Picture settings. The still picture configuration is only effective when the picture is stored on the device. The TX frequency configuration depends on the frequency offset and the RF Min and Max limits. The configuration of the data rate will affect the symbol rate and vice versa.

The transport stream is MPEG. Between symbol rate and data rate, a strict relation exists, which depends on the type of MODCOD, pilots insertion mode and input frame length. The device automatically provides the required cross calculations by enabling and disabling forbidden configuration. Null packet insertion is always enabled if the transmit clock is set to Internal. In this configuration, the symbol rate is only referenced to the internal reference clock.

DVB-S2 FEC Frame Length is only relevant if one of the DVB-S2 modulation types is selected. SHORT is not allowed if the selected modulation is of type DVB-S2 and the FEC rate is 9/10. Short BCH Code is only relevant if one of the DVB-S2 modulation types is selected and the DVB-S2 FEC length is selected as SHORT. Pilots and PL Scrambling are only relevant if one of the DVB-S2 modulation types is selected.

Monitor

This page allows you to monitor the Temperature (Front Panel, Modulator, Chip and Converter), the Modulator (Level IF Signal, Tune Voltage), the Carrier (Bandwidth, FIFO Fill Level) and the PSU DC Voltages.

System Configuration

This page allows you to configure the system. The State of the device can be loaded or saved and Autosave, Alarm Relay, External Mute Input and User Still Picture can be toggled. Banner and RF Min and Max frequencies can be set. System Info is also available, displaying the Name, Description, Date and Up Date. Firmware info about Front Panel, Main Module and FPGA is also displayed.

The following page buttons are available on this page:

  • SNMP: Displays the Trap Sink Server table, with up to 4 rows (one for each server), and information regarding the TCP/UDP ports and Read/Write Community.
  • Device States: Displays a table with information related to the stored devices.
  • M&C Interface Settings: Allows you to set up the M&C interface, with parameters such as Multipoint Address, Interface Type, RS485 TX and RX Termination, Packet Delay, Baud Rate, IP Address, Subnet Mask and Gateway. The page also displays the status of the ASI-A and ASI-B signals, SPI interface and auto mode.

With the Factory Reset button, you can reset the device to its factory status.

Status

This page displays the alarms and warnings of the device, listing up to 32 parameters related to the status of the device.

The following page buttons provide access to additional information:

  • Stored Events: Displays the history of events (up to 10 entries).
  • Stored Alarms: Displays the history of alarms (up to 20 entries).

Traps (from version 1.0.0.3 onwards)

Traps received from the device are displayed on this page in the Traps table. At the top of the page, you can choose whether traps are displayed in the table (Add to Table) or directly displayed in the Alarm Console (Create Alarm).

On the Auto Clear page, you can set up methods to automatically set limits on the number of rows in the Traps table.

Web Interface

This page allows you to access to the web UI of the device. 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.

DataMiner Connectivity Framework

From version 1.0.0.4 onwards, this connector supports the usage of DCF.

DCF can also be implemented through the DataMiner DCF user interface and through DataMiner third-party connectors (for instance a manager).
