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.

   IMPORTANT! This must be done before an attempt to connect.

3. 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.

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 just two examples:
