LINKAGE FOR MACHINES THAT DO NOT ENTER THE ROUTING SWITCHER
In some cases, machines may be wired directly to one destination, or to several destinations through distribution amplifiers
only (see Figure 5−126). Although these machines do not pass through the routing switcher, it is still possible to use switcher
control panels to establish linkages. In order to do this, imaginary switcher input and output names must be used as pointers
on the Machine Control menu. These names, along with imaginary physical I/O numbers, must be entered on the Switcher
Input and Output tables (pages 5−48 and 5−55). Also, the physical I/O numbers must be within the size range set on the
Switcher Description menu (page 5−35).
