Description
The
East Coast Datacom DBU-2328 is designed for use in RS-232 "receive
only" data broadcast applications. This unit supports up to eight
receive only terminals simultaneously. Examples of typical data
broadcast applications are; Continuously updated public data displays
and distribution of continuous data to Routers, PC’s or receive
only printers.
The expanding role of V-SAT systems in "receive only" applications
for real time data distribution is expected to increase dramatically
over the next several years. The DBU-2328 is an excellent choice
for applications of this type or any RS-232 simplex data distribution.
The DBU-2328 utilizes an RS-232 interface with data rate capabilities
up to 128Kbps. The unit supports up to eight receive only terminals
simultaneously. Surge protection is provided for all RS-232 data
interfaces and the power supply input.
The DBU-2328 continuously broadcasts receive data, receive timing
and an optional control signal(DCD) from the data source to the
eight output terminal ports. Each data port has independent drivers
and receivers for transmission.
The DBU-2328 supports cascading multiple units together from a
single data source for multiple outputs. The unit has a redundant
cascade port that utilizes positive latching relays. If a single
unit looses power, all remaining units will continue to function
without error.
The DBU-2328 is housed in a sturdy aluminum enclosure and is supplied
with an internal linear power supply. The unit has a 110/120 VAC
rotary select switch located on the rear of the housing. The unit
can operate on standard power found in all countries.
The DBU-2328 has a three year warranty and a 24 hour turnaround
on warranty repairs.
