Control connections

12MLC/IR port — This port allows you to provide remote control of the switcher. Connect a cable between this port and an optional Extron MLC 206 MediaLink Controller or an optional IR Link IR signal repeater.

The MLC provides remote control of input switching and volume.

The IR Link accepts modulated IR signals from a remote control so the remote control can be used for selecting the switcher’s inputs.

Extron Comm-Link cable is recommended for this connection. If you use Comm-Link cable, the switcher and controller can be up to 250 feet (76.2 m) apart. Wire the captive screw connector for connection to either an IR Link or an MLC 206 as shown below.

If the switcher is connected to an MLC 206 controller via the MLC/IR port, do not connect an RS-232 device to the MLS’s 9-pin RS-232/Contact Closure port. The 9-pin D and 5-pole captive screw connectors are both for RS-232 control.

Connect devices to both ports at the same time only if

the 9-pin connector is used for contact closure and

the MLC/IR port is used for RS-232.

13RS-232/Contact Closure port — This port can function as an RS-232 port or as a contact closure port. Do not connect RS-232 devices to both this and the MLC/IR port. See the above note.
