DESCRIPTION
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 10Mbps. 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.
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.
