Edition 09/2006 V1.5
The DiRaBox DRB 30 is a computer-controlled black box receiver without own operating elements. Computer control is
provided by the rear panel parallel interface port (LPT). Only the outer connectors have to be connected to the appropriate
devices.
Please note: For error-free operation it is necessary to connect the power supply after starting up the ControlPanel software. If problems occour
please disconnect the power supply for some seconds which causes a hardware reset.
