... This section shows the schematic and connec- tions to DC590A, which DC590B replaces. The only functional difference between DC590A and DC590B is that the digital signals on DC590B can be adjusted from 2.7 to 5V, where the DC590A is 5V only. DC590B also offers improved isolation, as all 14 conductors on the 14 pin interface header are iso- lated from the PC’ ...
