•For a stand-alone MLS switcher, connect a cable from the host computer or a third party control system to this 9-pin D connector to set up and remotely control the switcher. Alternatively, connect a contact closure keypad to this connector for remote control of input selection.

•For an MLS switcher slaved to an MLC controller, connect a cable from the MLC’s MLS/Power port to the switcher’s MLC/IR connector (not to this 9-pinRS-232 port). Once the system has been cabled and set up via the Windows-based software, the MLC or a host computer communicating through the MLC can be used to remotely control the switcher. Refer to chapter four of the MLC 206 User’s Manual and the MediaLink Control Program help file for details on configuring an MLC- MLS system.

CAUTION

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. Conflicts between RS-232 signals received from both ports could cause system disruptions.

When an MLC 206 is connected to the MLC/IR port, a contact closure device may be attached to the 9-pin connector.
