The Data Broadcast Unit, DBU-232 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-232 is an excellent choice for applications of this type.

The DBU-232 utilizes an RS-232 interface with data rate capabilities up to 128Kbps. The unit can support up to 3 receive only terminals simultaneously.

The DBU-232's master port has a DB-25 female connector. The sub-channels are also DB-25 female connectors.

The DBU-232 continuously broadcasts receive data and receive timing signals from the data source to the 3 output terminal ports.

The DBU-232 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-232 has a three year warranty and a 24 hour turnaround on warranty repairs.
