Make sure E1 is configured for the correct analog output number selection.
If another module is in use, such as another analog or multi-scale module, connect it to J2 (NEXT) on
the previous module.
If any I/O modules are to be installed, they must be daisy chained after all multi-scale and analog
output modules.
Route any cables through a strain relief making sure to connect any shield wires to a ground stud.
