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

1. You need a RS422 controller that installs the RS422 port as a new COM port in Windows.

2. Set up the XtenDD35 protocol on the used remote port of the EVS video server.

3. Manually set the Windows COM port settings to:

   • 38400 baud

   • 8 bytes

   • one stop bit

   • odd parity

4. 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.

5. 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:
