4.1.2 Port Driver (TV Encoder DLL) Options
The port driver (TV encoder DLL) options control the selection of the port driver and the discovery of the TV
encoder device.
I2cPin <DWORD>
This setting selects the I
2
C* bus. (Value of 1 usually identifies DVO-A, 4 usually identifies DVO-B/C)
I2cDab <DWORD>
This setting selects the Data Address Byte (DAB) for the TV encoder silicon in the system. The DAB is normally
specified by the port driver itself, but this setting allows for customization if needed.
PortOrder <STRING>
This value determines the order that the DVO ports and analog (VGA) port will be enumerated. This also controls
the order in which the driver will detect TV encoders. This is especially important for DVO-B and DVO-C devices
because they share the same I2C bus. The PortOrder string should include the analog (VGA) port number and the
single DVO port that is in use. To avoid confusion, do not refer to multiple DVO ports.
The following setting on the 854 specifies to enumerate the DVO-B port (2) and then the analog (VGA) port (5).
"PortOrder"="2500"
The following settings is required for “Shadow” DVO mode on the 854 with the Conexant CX23899 and Silicon
Image 9030 HDMI transmitter.
“PortOrder”=”2350”
PortDrivers <STRING>
This value determines the port driver DLLs that are loaded. A port driver is needed for TV encoders and is used
when the DigitalPort is set to DVO or Twin. This string should contain a single port driver.
The following setting for the 830 specifies to load the Focus fs454 DLL.
"PortDrivers"="fs454"
The following setting for the 854 specifies to load the Conexant cx873 DLL. Note: The Conexant cx873 DLL
supports both the CX25873 and CX25892 TV encoders.
"PortDrivers"="cx873"
To load the Silicon Image 9030 port driver in single DVO mode.
Note: Using the sii9030 port driver in this mode requires a port order of “5300”
“PortDrivers”=”sii9030”
To load the Conexant CX23899 and Silicon Image 9030 HDMI port driver in “Shadow” DVO Mode.
“PortDrivers”=”cx873 sii9030”
DebugPortMessage <DWORD>
This setting is used to turn on or off the debug messages in port driver module.
