The 7882DM2-LB4-CA2-ASI Series is a comprehensive hardware-based solution designed for demodulating digital DVB-S/S2/S2X satellite signals. Its modular form factor, coupled with multiple inputs and demodulators per card, positions it as a high-density and flexible solution in the industry. This device is particularly suited for applications in cable, DTH, and IPTV providers, as well as for head-end operators requiring satellite content reception and redistribution. The series provides ASI outputs, making it ideal for turnaround, transcoding, monitoring, or other applications where the received signal remains in the compressed domain. For baseband output, the demodulator can be paired with an Evertz decoder module to offer a complete IRD solution.
Function Description
The device is capable of multi-stream reception and supports DVB-S, DVB-S2, and DVB-S2X standards. It includes four DiSEqC 1.x compatible transmitters (22-kHz) and one DiSEqC 2.x compatible receiver (22-kHz). A key feature is its signal quality monitoring, which includes Es/N0, demodulator lock status, RF power, MER, Bit Error Rate, Frequency Offset, and FEC activity, all selectable among internal demodulators. These parameters, along with full control of the demodulator, are accessible via SNMP, facilitating remote access through Evertz's VistaLINK® PRO SNMP monitoring and control package. For decryption needs, the 7882DM2-LB4-CA2-ASI is equipped with dual slots for customer-supplied DVB-CI compliant conditional access modules. It offers standard support for advanced transport stream processing, including service filtering and output bitrate control. The device also supports advanced modulation schemes, such as DVB-S2/S2X with 16APSK, 32APSK, and 64APSK, and handles both long and short frames. It is compatible with CCM, VCM, and ACM modes, and supports both SCPC and MCPC. Automatic detection and configuration of modulation type, filter roll-off, symbol rate, pilot presence (on/off), and frame length are also integrated. The flexible transport stream processor allows for PID filtering and bitrate control. Furthermore, it supports on-board input auto-failover between various inputs, including RF or ASI inputs, and offers optional BISS and BISS-E decryption.

Usage Features
The 7882DM2-LB4-CA2-ASI is controlled via a web interface, WebEASY®, which uses Ethernet and SNMP control protocols. It also supports control through VistaLINK® PRO. Initial setup involves configuring the management IP connection through a serial port, allowing access via a local area network. Users can log in with different credentials for read/write ("root" / "evertz") or read-only ("customer" / "customer") privileges. The web interface provides various menus, including Input, TS Path, Output, Descramble, TS Tree View, Preset, System, and Notify.
- RF Tune: Users can tune individual demodulators (up to four per module) by selecting the corresponding tab, modifying the tab name, entering satellite frequency, LNB frequency, and symbol rate. The system can auto-detect modulation type, filter roll-off, symbol rate, pilot presence, and frame length. The "Lock Status" confirms signal tuning.
- LNB Control: LNB power (13V, 18V, or OFF) can be set for individual input ports.
- TS Path: Users select the input source from four RF inputs and four ASI inputs. Source mode can be set to "Force Main," "Force Backup," or "Auto" for redundancy. Parameters like Bitrate, PID Count, Sync Loss Error, Sync Byte Error, CC Error, and Services are monitored. ASI ports can be configured as input or output.
- Output: The TS output status and control section monitors output parameters such as Bitrate, PID count, and various error counts.
- Descramble: For DVB-CI CAM descrambling, users configure initial parameters under the "System" tab, including CAM Enable, Multi Service Mode, Maximum TS Bitrate, and CAT Info Pass Through. On the "Descramble" page, users select services to descramble, and the "Output Encryption" status changes from "Scrambled" to "Free." Up to 30 programs can be descrambled per CAM.
- TS Tree View: This section allows users to view incoming programs on the source TS, including elementary components and PID values, by clicking on service names.
- Preset: Up to 60 presets can be saved and recalled, allowing users to store and load configurations. Presets are organized into three tabs (1-20, 21-40, 41-60).
- System: This section allows users to reboot or factory reset the module, view card type and set an alias for the unit. It also includes configuration import/export features.
- Notify: Users can enable/disable traps for LNB faults and demodulator faults to receive notifications. Square boxes indicate fault status (RED for fault, GREEN for no fault).
Maintenance Features
- Firmware Upgrade: Firmware upgrades can be performed via VistaLINK® PRO or WebEASY®.
- VistaLINK® PRO: Right-clicking on the 7800FR frame in the hardware tree and selecting "Version Information" allows simultaneous upgrades of multiple 7882DM2-LB4-CA2-ASI modules. Users select the firmware archive (.tar.gz) and initiate the upgrade. After transmission, the module reboots.
- WebEASY®: Users select the "Upgrade" tab, browse for the firmware file, and click "Upgrade."
- VistaLINK® PRO JAR File Upgrade: To access the latest features and enhancements, JAR files for VistaLINK® PRO must be updated. This is done by maximizing the VLPro Server window, selecting "Help > Apply Update > Product," navigating to the new JAR file, and restarting the server.
- Configuration Management: The "System" tab allows importing and exporting configuration files, enabling easy backup and restoration of settings.
- Alarm Monitoring: VistaLINK® PRO provides an alarm window that displays a list of triggered traps, including description, date/time of trigger, device, date/time of correction, and duration. This requires a valid destination to be specified for SNMP V1 Trap on the FC web page.
- Troubleshooting: The manual provides guidance for common issues, such as ensuring the PC is on the same subnet for management access and power-cycling boards if firmware upgrades fail.
