Data Switch Panel Model DSP-101

The DSP-101 Data Switch Panel is designed to select data from any one of twenty-four BNC connectors and route this data to any one of three BNC output connectors. Data routing from the input connectors to the output connectors is actuated by three banks of twenty-four switches or from a computer through an optional RS-232 interface. The switch panel has three monitor switches which route the data from the DATA-A, B, or C output connectors currently selected by switch bank A, B, or C to the monitor connector. A memory is included with the DSP-101 that stores the current switch conditions for banks A, B, and C, and the monitor switches whenever the prime power is interrupted. The memory restores the switches to the conditions they were in prior to the interruption of power when prime power is restored. Source and termination impedance should be considered during the installation to maintain signal integrity as the DSP-101 input and output connectors are not terminated.
The DSP-101 operates from 110 VAC, 60 Hz and is capable of handling signals from DC to greater than 20 MHz. The optional RS-232 interface is enabled by setting the local/remote switch to the remote position. An individual switch on banks A, B, and C will be illuminated indicating which input is currently routed to the output connector for that particular bank. The monitor switches for banks A, B, and C will be illuminated indicating which switch banks data is currently routed to the monitor connector. Switch conditions will be illuminated whether they are selected by the front panel switches or the RS-232 interface.
