2-5Matrix 50 Series Switchers • Installation
You can also connect an MKP 1000 remote keypad or MCP 1000 slave unit to
the MCP 1000 master unit. Refer to the MCP 1000 Remote Control Panel User’s
Manual and the MKP 1000 User’s Manual for details.
See chapter 4, Programmer’s Guide, for definitions of the SIS commands and
chapter 5, Matrix Software for details on how to install and use the control
software.
The Matrix 50 Series Switchers are factory configured for RS-232 control. To
use the switcher under RS-422 control, an internal cable must be moved. See
appendix B for the procedure for shifting the cable.
External sync connection
When the switching between inputs, the resulting image change should be
seamless, or clean. The Matrix 50 Series switchers 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.

External Sync In connector — Connect an external sync signal to this BNC
connection for genlocking the video signal in broadcast or other sync-critical
applications.
External Sync 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. The Ext Sync In connector
receives a timing signal. The Ext Sync Out connector allows the signal to be passed
on to another video device, if required.
Figure 2-9 shows a configuration in which the timing source passes through three
video cameras and a video scan converter before connecting to the switcher. This
type of video camera is capable of synchronizing with the external timing source
for video editing applications.
If no external sync timing source is connected to the switcher, switching occurs
immediately.
