Single Video Reference
Since there is only one video reference in this example shown in Figure 37 ,
it must be selected for use by all input and output boards. On systems with
the CX-34000 Control Crosspoint boards (all present systems), this selection
is made with DIP switches marked REF; all these switches would be set to
binary 0. For the location of these switches, see
page 98 .
