ONFIGURING
Once you’ve finished setting the Converter’s configuration switches,
don’t
snap the case halves back together yet. If you are connecting the RS-485
interface using the internal terminal blocks, go to
Section 4.1.2
and
continue the installation procedure. If you are connecting the RS-485
interface using DB25, go ahead and snap the case halves back together
now. (Don’t force a fit—make sure all the pieces are properly set before
snapping the case halves shut.)
