Tredess FS
The Tredess FS (Fourth Series) connector can be used to configure and monitor a digital TV transmitter. This device is responsible for the correct functioning of terrestrial and satellite transmitters.
The connector retrieves and sets data via SNMP. If this is enabled on the device, SNMP traps can also be retrieved.

Configuration
Connections
SNMP Connection - Main
This connector uses a Simple Network Management Protocol (SNMP) connection and requires the following input during element creation:
SNMP CONNECTION:
- IP address/host: 10.145.1.35
- 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. The default value is public.
- Set community string: The community string used when setting values on the device. The default value is private.
Web Interface
The web interface is only accessible when the client machine has network access to the product.
Usage
System
This is the default page. It displays general information, including the language, name, temperature, time sources (such as NTP), general device information and settings.
The following settings can be accessed via page buttons:
- Network interfaces: Configuration of the remote interface and local interface, and monitoring of the link status.
- Web interface: Configuration of the auto-refresh and the passwords for users/admin.
- Event configuration: Several tables where information from the individual parts/interfaces can be edited/monitored.
- SNMP: Configuration of the agent, including read/write community and traps.
- Service: Monitoring of the 3 fans, with the possibility to reset them with a reset button. Monitoring of the DC power supply, calibration and reset of the system.
Polling Configuration
From version 1.1.1.4 onwards, a Polling Configuration page is available, where you can define the polling intervals for the following groups of parameters:
- System
- Web Configuration
- Network Interfaces
- Software Update
- Service Slow
- Service Medium
- SNMP
- Alarm Configuration
- Event Configuration
- IO Interface Medium
- IO Interface Fast
- Hardware Basis
- Hardware Options
- Software Options
- Input
- Exciter RF
- IF Processor System
- IF Processor Echo Canceller
- IF Processor Precorrector
- Mute Configurations
- Exciter Modulator Slow
- Exciter Modulator Medium
- ISDB-T Configurations
- DVB-T2 Configurations
- DVB-T2 PLP Configurations
- DVB-T Configurations
- Reference
- Amplifier
- Status
- Input Status
- Modulator Status
By default, polling for these groups is enabled, and the polling intervals for these groups are the same as in previous versions of the connector: 10 seconds for fast parameters, 1 minutes for medium parameters, and 1 hour for slow parameters.
In the Polling Table, you can configure the intervals in the Time column, enable or disable the polling in the State column, and poll a specific group on demand in the Refresh on Demand column.
Input
This page is used for the configuration/monitoring of the input switching and IP sockets.
Exciter RF
This page contains parameters for the configuration/monitoring of the output frequency.
Exciter Modulator
This page contains information about the modulator, such as the temperature. The page also contains page buttons, which among others allow you to select the type and edit DVB-T settings.
Reference
This page provides information about the reference. Here you can select which type of reference you want and the switching mode. In addition, information about the synchronization module is monitored.
Amplifier
This page provides information about the amplifier, such as configured power, forward and reverse power, thresholds, temperature, and transistor currents.
Redundancy
This page contains information about the redundancy. Several parameters are monitored, and it is also possible to edit the configuration of the auto-verification.
Status
This page contains status parameters for the entire connector. The status parameters are polled and updated based on received traps.
Web interface
This page displays the web interface of the device. The address of the host/web UI is the same as the polling IP of the element. 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.
Notes
There are several known issues in the device:
- The device returns GENERIC_ERROR when you try to set event configurations.
- Some parameters that are included in the MIB are not available on the device: rfinput, echoCanceller, modLinearPrecorrection, modNonLinearPrecorrection, modEfficiencyImprovement, modClipping, modPrecorrectorLevels, some parameters related to synchronization, and some status parameters.
- Elevated Power Threshold and Reduced Power Threshold: When a set is performed via the MIB, the device responds with a bad value error. When the set is performed via protocol, the device does not respond.
- Tag column in the Rack Cooling table: When a set is performed via the connector, the device responds with a WRONG LENGTH error. Because of the specific setup where this issue occurred, it could not be verified further. Packet capture will be required to verify if it is a firmware issue.
