DESCRIPTION

The DBU-16 is designed for use in receive only async data broadcast applications. The unit has two separate input ports, capable of accepting RS-232 or RS-422(or any V.11 compliant interface) data. The user must select, via a slide switch the preferred input method. Additionally, the unit has a dedicated cascade port for chaining DBU-16 units together.

The DBU-16 continuously broadcasts receive data from the input port. The input signals are split with the internal circuitry and rebroadcast out on sixteen output ports. The output ports are divided into four modular cards. Each modular card has four output ports capable of RS-232 and RS-422(or any V.11 compliant interface). Front panel LED indicators illuminate in green or yellow depending on the data type(RS-232 or RS-422).

The user may also utilize the DBU-16 as a interface converter. This function allows RS-232 input data to be broadcast as RS-422 data or RS-422 data to be broadcast as RS-232 data. Utilizing RS-422(V.11) can support data transmissions at far greater cable distances than does RS-232. The DBU-16 can support an unlimited amount of receive only devices simultaneously.

The DBU-16 is housed in a sturdy aluminum 1U rackmount enclosure and is supplied with an internal linear power supply. The unit has a 110/220 VAC rotary select switch located on the rear of the housing.
