The pulse signals from Y0 and Y1 outputs will typically go to drive input circuits as
shown above. Remember that the DL105’s DC outputs are sinking -only. It will be
helpful to locate equivalent circuit schematics of the drive amplifier. The following
diagram shows how to interface to a sourcing drive input circuit.
