Extron switcher control connections
6 Contact closure Tally Out(put) connector — To effectively add more A/V
inputs to a projector, you aren’t limited to using a MediaLink switcher. If
desired, attach an Extron switcher that accepts contact closure control to this
3.5 mm, 6 pole direct insertion captive screw connector. Each pin corresponds
to a switcher front panel button. When a tally pin is selected, the pin changes
from a high (5V) to a low (0V) state. This momentary high-to-low change can
be used to trigger switching on various contact closure controllable Extron
switchers.
Wire the connector as shown here.

You must connect the ground pin of the switcher’s connector to a ground
connection on the MLC.
Only Extron switchers can be slaved to the MLC via this tally output contact
closure connector.
7 MLS/Power connector — Connect a cable between this 3.5 mm, 4-pole direct
insertion captive screw connector and an optional Extron MLS switcher for
RS-232 control of the switcher and to provide power from the switcher to the
MLC. See the following diagram. With Extron Comm-Link cable, the
switcher and controller can be up to 250 feet (76.2 m) apart.
The commands issued from this port are standard Extron SIS™ commands,
and they follow the Extron switcher protocol (9600 baud rate, 8-bit, 1 stop bit,
no parity). The commands sent via the MLS/Power connector are fixed and
cannot be altered. See page 3-3 for additional details.
