EVS Video Server Control
An EVS Control Plug-in lets the Viz Engine control an EVS video server (like a tape deck over RS422). This gives Viz Engine the ability to load and control playback of EVS video server clips.
This section contains information on the following topics:
Setup Requirements
-     
The computer which runs the Viz Engine must be equipped with an RS422 controller that maps the controller ports to the Windows COM ports.
 -     
The RS422 port must be connected to an RS422 remote controller port of the EVS video server.
 -     
The EVS player, controlled by the RS422 port, must be set up to use the protocol XtenDD35 (No other protocol is currently supported).
 
RS422 and XtenDD35 Configuration
-     
You need a RS422 controller that installs the RS422 port as a new COM port in Windows.
 -     
Set up the XtenDD35 protocol on the used remote port of the EVS video server.
IMPORTANT! This must be done before an attempt to connect.
 -     
Manually set the Windows COM port settings to:
-     
38400 baud
 -     
8 bytes
 -     
one stop bit
 -     
odd parity
IMPORTANT! This must be set before Viz Artist is started.
 
 -

Usually, a special RS422 cable is required to connect the controller to the EVS video server. It is recommended to use a connector cable to connect the RS422/DB9 connector to a standard RS422 cable. The RS422 cable should work with a normal EVS video server controller.
 -     
Every RS422 controller has a different pin-out setting and requires a different connector cable. The table below shows which signal of the RS422 controller must be connected to which pin on the EVS side:

RS422 Controller Set Up Examples
The connection of a RS422 controller to the EVS is always different for each controller. Here are two examples:
