    I am using JCG1524D12 dc/dc converter for generating bipolar from unipolar supply. After right connecting 24v to input i got +/-12 from output, and the 5V i got from 7805 connected on the 12V . That bipolar supply i am using for some ina128, ina163 ,..Output from electronc is singleout so i connected the outer contact of mine uotput bnc connector to gnd and also that gnd is connected to the input gnd.
    I dont get right output, either all ic works properly and there is still +/-12V and +5V.
    I drow simplle block diagram in word.

    Is that connection mistake?
