MLS connector — For controlling an optional Extron switcher or other RS-232
controllable device, connect a cable between this 3.5 mm direct insertion
captive screw connector and the RS-232 port of the other device.
The commands issued from this port are standard Extron SIS
™
commands, and
they follow the typical Extron protocol (9600 baud rate, 8 data bits, 1 stop bit,
no parity).
If you connect an optional switcher (such as an Extron MLS Series switcher) to
the MLC, you must connect a ground wire between the switcher and the
MLC, as shown in the following diagrams.

between this port and a 12 VDC, 1 amp (maximum) power supply. See the
following diagram.
Power the controller via an external power supply, not from an Extron
switcher. The controller requires a separate 12 VDC power supply.
