Extron electronic MAV 48 External sync connection, Shows a basic external sync configuration

Using the hardwired IR input on pin 9, you can use a control system with IR-learning capabilities to operate the switcher just as if you were using an IR 501 remote control. The control system must first “learn” the IR command from an IR 501, after which it sends the same commands to the MAV via pin 9.

External sync connection

The MAV switcher switches between inputs during the vertical interval period, resulting in glitch-free video switching. The MAV switcher can use an external signal to synchronize switching during the vertical interval. Without the external sync locking feature, switching between inputs can result in a brief rolling (sync loss) or a brief change in the picture size.

10Sync In connector — Connect an external genlock signal to this BNC connector for genlocking the video signal in broadcast or other sync-critical applications.

11Sync Out connector — Connect any downstream equipment that requires genlocking to this BNC connector to route the external sync signal throughout the system in broadcast or other sync-critical applications.

Figure 2-8 shows a basic external sync configuration.
