Reference Connections
Single AES Reference
Since there is only one AES reference in this example shown in Figure 38 , 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 1. For the location of these switches, see
Figure 41 on page 98 .
