3.6 Automation Using RS-422
Some card behaviors can be controlled using the RS-422 port. This is especially useful for automation
systems. For detailed information about the protocol including the handshaking, please refer to the Oxtel
Series Automation Protocol manual. The "Transport Layer" chapter gives more details about the
encapsulation of the command strings described below.
In the current version, we use the "Load image R0" command from the protocol to load User Presets, Factory
Defaults or ARC Presets.
3.6.1 Load Image R0 Command
•
In the original protocol, the R0 command has 2 parameters which have been renamed "Layer" and
"Oper_String" for this application. The supported values for each of these parameters are defined in the
tables below.
Layer '0' is used to load User Presets or the factory defaults. Layer '1' is used to load ARC Presets.

Example:
To convert a 4:3 input to 16:9 with 25% side panels at the output, the " R010-1-SIDE25" command string
should be encapsulated and sent by the automation to the card. In this case, the final string would be:
<STX0>R010-1-SIDE25:<CRC low><CRC high>
Where <STX0>, <CRC low> and <CRC high> are described in the Oxtel Series Automation Protocol manual.
