The UDC-DBU Data Broadcast Unit is designed for use in receive only data broadcast applications. Examples of typical data broadcast applications are; Continuously updated public data displays and distribution of continuous noncritical data to 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 UDC-DBU is an excellent choice for applications of this type.

The UDC-DBU input port accepts a variety of DTE models manufactured by East Coast Datacom, Inc. with support for RS-232, RS-530, RS-422/449, X.21 and even TTL. The units output ports can support up to four receive only terminals simultaneously for either RS-232 or balanced V.11 on RJ-45 connectors.

The UDC-DBU's master port has a DB-25 female connector. The sub-channels are also DB-25 female connectors.

The UDC-DBU continuously broadcasts receive data and receive timing signals from the data source to the 3 output terminal ports.

The UDC-DBU 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 UDC-DBU has a three year warranty and a 24 hour turnaround on warranty repairs.
