Digitimer Ltd – D400 Operator's Manual

Hardware Overview

The D400 is designed for ease of use, has very few controls and is essentially "plug and

play". There are three push buttons on the left of the front panel and to the right of these

are multiple pairs of signal input and output connectors, as well as equivalent 9-way "D"

connectors for all channels. Associated with the individual signal connectors are several LED

indicators which show the status of each channel (see below).

Power LED

Once powered on, the D400 will enter a start-up stabilisation phase signified by the front

panel POWER LED flashing green for approximately 40 seconds. This LED will be

permanently lit once the D400 is ready to use.

Signal Input/Output Connectors

The D400 offers the user two alternative methods for signal input and output connection.

For each channel there is a pair of standard BNC connectors designated "Inputs" and

"Outputs". In addition, two 9-way "D" connectors are available for combining input and/or

output signals via the supplied signal input/output cables.

The operational signal range of the D400 is ±10V and amplifiers or signal conditioners

providing voltages in excess of ±10V are not compatible with the D400.
