8. CONNECTION TO SETTING AND DISPLAY UNIT
When the two–path Power Mate i–D is provided with two detachable
LCD/MDI attachment positions, the display link (RS–485) will have a T
branch. Minimize the length of this branch. No more than one detachable
LCD/MDI can be connected to a display link at any one time. Further
details are given in Subsec. 8.5.3.
The ATCH signal shown in the figure in Subsec. 8.5.3 can be used to
automatically change the path to be displayed according to the attachment
position. The displayed path can be selected by the PMC. When a
detachable LCD/MDI is attached to each attachment position, the
displayed path can be changed automatically by using the ATCH signal
to turn on the corresponding DI signal.
