The DBU-V11/FB is designed for use in receive only data broadcast applications while allowing redundant data feeds. The DBU-V11/FB continuously broadcasts receive data, receive timing and Indicate (any user defined control signal from the main input data source may be used). The input signals are split with the internal circuitry and broadcast out on the seven output ports. An additional dedicated cascade port is provided for cascading DBU-V11 units without loosing a sub-channel port.

The DBU-V11/FB utilizes an ITU V.11 (X.21) balanced interface with a maximum data rate of up to 20Mbps. Additionally, V.11 can support data transmissions at far greater cable distances than RS-232 signal levels. The unit can support an unlimited amount of receive only terminals simultaneously. An ideal solution for radar data distribution.

The DBU-V11/FB's input data ports have tandem DB-15 female connectors. This allows a dedicated input port and an additional input port as the fallback port. The integral fallback switch supports switching modes of automatic or manual. The unit will monitor data, clock or Indicate control signals for switching.

The DBU-V11/FB is housed in a sturdy metal enclosure for standalone or rackmount applications. The unit is equipped with an internal 110/220VAC switch selectable linear power supply and has a three year warranty.
