Monitoring & Control Modules

The ViaLite ‘Horizons’ Monitoring and Control (M&C) modules can be used to fully manage ViaLiteHD RF over fiber systems.  The HRC-3 Horizons option allows for inter-facility control and can be multiplexed using CWDM, or used over extreme distances with DWDM. It can also be used with optical fiber to extend existing Ethernet networks from point-to-point (e.g. from a control room to the antenna in a satellite earth station) and optionally from point-to-multipoint.

ViaLite‘s Horizons software can be used with existing ViaLite M&C modules.

Features can include:

  • Full remote management with integrated web GUI or SNMP MIB
  • MIB can be integrated with all major satcom NMS systems
  • 10/100/1000 Mbps switch, 3 ports including 2 optional optical or Ethernet ports
  • Support for dual optical Ethernet configurations allowing daisy chaining or star network configurations
  • Micro-USB control port
  • Not Java dependent
  • Maintenance mode allowing modifications to be carried out offline
  • Real time monitoring of card performance & redundancy switching.

Please see the Features Guide here for more information.

The new Embedded Site Controller is also available for M&C of outdoor enclosures.

  • Standard micro-USB setup port
  • 5-year warranty as standard


ViaLite Horizons GUI

Horizons is standalone software required to operate the legacy HRC-1 and comes built into the HRC-3.

The GUI offers a representation of ViaLiteHD modules in a connected rack chassis (3U or 1U).  It displays the operational status of the modules and power supplies, along with the voltage and temperature of the module. The built-in interface can be accessed from any standard web browser using the IP address of the module.


Simple install

The M&C module allows any user to quickly setup local and remote ViaLiteHD equipment by accessing the front panel LAN port on the card.  Under normal operational conditions, the card can be permanently connected to the user’s network and the health of the ViaLiteHD system can be monitored at any time.


Management information base (MIB) tables

The open architecture of the M&C modules’ MIB allows management of the alarm information using any SNMP-compatible third party network management system (NMS), when connected via the local area network (LAN). The MIB is common to all ViaLiteHD M&C products.


Summary Alarm Monitoring cards for in-rack alarms

In addition to the M&C modules which can be used for alarm monitoring via a GUI, ViaLite‘s Summary Alarm Monitoring cards can be used within rack chassis to monitor the rest of the fitted equipment.  These cards are able to report alarms by front panel visual indicators, audio alarms and by the status of the card’s on-board relays – which can be used to trigger the customer’s alarm monitoring equipment.

On start-up, the Summary Alarm Monitoring card analyzes the active, populated slots within the chassis to allow for the empty slots to be ignored.

The cards monitor all chassis alarm outputs, or DIP switches are available for manual alarm screening if preferred.

ViaLite‘s Embedded Site Controller option is available for the ODE-A4 range of outdoor enclosures and the ODE-MINI; ViaLite‘s smallest enclosures. It allows monitoring and control of the RF over fiber links inside.


  • Ability to integrate enclosures into Network Management Systems (NMS)
  • Gain Control allows for optimization of RF signals in the field
  • Set minor, major and trigger-point alarms
  • Maintenance Mode – allows for the masking of alarms
  • Modern and easy-to-use, intuitive design based on the Horizons HRC-3 Controller software.
  • Event history log
  • System reports. – Store system configurations and operations, and share or use these for remote diagnosis
  • Software upgradable; benefit from post-delivery updates.
