The East Coast Datacom Data Broadcast Unit, DBU-V.11 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 DBU-V.11 is an excellent choice for applications of this type.

The DBU-V.11 utilizes an ITU V.11 compliant electrical interface with data rate capabilities up to 20Mbps. Additionally, V.11 supports data transmission at far greater distances than does RS-232. The DBU-V.11 can support up to 8 receive only terminals simultaneously.

The DBU-V.11's master port has tandem DB-15 connectors allowing the DBU's to be cascaded without loosing any subchannel ports. The DBU-V.11 continuously broadcasts Receive Data, Receive Timing and Indicate control signals from the data source to the 8 output terminal ports.

The DBU-V.11 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-V.11 has a three year warranty and a 24 hour turnaround on warranty repairs.
