914-HDE Multiplexer

The Focal 914-HDE is an extremely compact, single card solution for High Definition (HD) video, Gigabit Ethernet and multiple serial data channels.

The 914-HDE is targeted for use with small Remotely Operated Vehicles (ROVs), HD video broadcast, ROV survey upgrades or defense Electrical Optical (EO) pods.

The 914-HDE fiber optic multiplexer combines Focal’s expertise in Time Division Multiplexing (TDM) and replaces multiple media converters and optical multiplexers reducing size, weight, power and cost.

The 914-HDE supports advanced features, such as: real-time diagnostics over a dedicated RS-232 channel, video overlay with real time user updates (e.g. for GPS, altimeter), field-upgradable firmware, and software configurable serial data formats.

Diagnostic readings may be accessed via an RS-232 serial link in real time by using Focal™ Graphical User Interface (GUI) software, based on the Microsoft® .NET Framework, or by using a customer’s own software configured to read Focal’s serial ASCCII protocol or Modbus ASCCII format.
