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.

Connect the switcher's
contact closure
ground pin to a
ground on the MLC.
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.

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.
