Special Applications
There are numerous ways to use a MediaLink Controller or another IP Link device to control
and monitor AV systems. The
Global Configurator Help file and earlier sections of this guide
cover typical uses and features. This section shows you how to set up the MLC for a few
specialized applications:
• Using Monitoring to Make Functions Track Actual Conditions
• Working With Combination Source Devices
•
Scheduling Front Panel Lockout Periods
• Sending E-mail by Pressing a Button
• Working with a Non-MediaLink Extron Switcher
• Using Digital Inputs
•
Using Digital Outputs
• Using an Amplifier and Volume Controller with the MLC
• Customizing HTML Files to Control Devices, Modify Embedded Web Pages,
and Send E-mail Alerts
Before configuring the MLC,
1. Connect cables between the MLC, the controlled devices, any optional control panel
(SCP) or control module (IRCM, CM), and the PC as described in
Operation, Features,
and Cabling starting on page 7.
2. Install and start the Global Configurator software, create or open a GC project, and
add an MLC to the project, if that has not already been done. For instructions, see the
Global Configurator Help file.
3. In Global Configurator, add device drivers and assign them to the appropriate ports.
Instructions on these tasks are included in the
Global Configurator Help file.
Using Monitoring to Make Functions Track Actual Conditions
If users have access not only to the MLC but also to the control panels or remote controls
of input and output devices, they can directly change various kinds of device status and
settings without using the MLC. This can create a discrepancy between the actual status
of the device and the status known to the MLC. Status discrepancies can also happen
in installations where the MLC is the only control device in a room. Most projectors
automatically unmute when receiving an input change command. So, if inputs are switched
via the MLC front panel while video is muted at the projector, the projector unmutes itself,
and the MLC is not aware of that change. To avoid those discrepancies when configuring
MLC button functions and scheduling events, you can set up a monitoring routine.
For example, let’s say that you set up an MLC front panel button (such as the input 4 button)
in toggle mode to send the projector a video mute command on one press and a video
unmute command on the next press. If you press the input 4 button once, the MLC sends
the video mute command. The next time you press that button, the MLC sends the video
