F Contact In and Tally Out — Six 3.5 mm, 3-pole captive scrw connectors for
automatic input switching and tally indication using Extron Show Me cables.
When a connected contact is grounded, the corresponding input is selected. At the
same time, the tally output closes causing the Show Me LED on the connected cable to
light (see
Contact Closure and Tally Output Application Diagrams on page 7).
NOTE: For Show Me cables, the ground pin connection is optional.
The six contacts are mutually exclusive so that only one input is selected at at time.
