Switcher Module Description
Serial Reentry Module (064822)There are two Serial Reentry Modules (SRE). The SRE Modules are used to
reenter some switcher outputs back into the switcher and enter some of the
internally generated signals into the switcher. Reentered signals are then
sent to the crosspoint module where they are treated the same as any other
video or key. Table 3-1 summarizes the uses of both the Reentry Modules.
SRE Module 1 is in input slot C6 and SRE 2 is in input slot C5.
