Description

The East Coast Datacom RS-232 data broadcast unit, model DBU-2328 is designed for use in RS-232 receive only data broadcast applications. 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.
