3.5 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.

3.5.1 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.

Command Layer Oper_String Description

R0 0 USER_1 Load user preset 1

R0 0 USER_2 Load user preset 2

R0 0 USER_3 Load user preset 3

R0 0 USER_4 Load user preset 4

R0 0 USER_5 Load user preset 5

R0 0 FACTORY Load factory default

Example:

To recall the USER_1 set of parameter, the " " command string should be encapsulated and sent by the

automation to the card. In this case, the final string would be:

Where <STX0>, <CRC low> and <CRC high> are described in the Oxtel Series Automation Protocol manual.
