Viz Engine Administrator’s Guide

• 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 Setup

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:
