DVDO iScanHD

Make/Model	Device Version	Connection Type
DVDO/iScan HD	N/A	Serial

Description:

This driver controls the DVDO iScan HD video scaler. The iScan HD is a full featured video scaler/switcher that supports composite, S-Video, component/RGB, DVI, and SDI inputs, as well as being able to switch audio sources.
This driver's server side component is CML based, and is in the MEng.System.CQC.Drivers.iScanHD scope.

Quirks and Limitations:

Some values are not accepted by the iScan HD when it is in certain states. For instance, you cannot set the Hue when the current input doesn't support a Hue value, such as component. Or you cannot set film mode when some inputs are selected and there is no input signal. When you this, the driver will reject the written value to let you know it failed.

Connection Details

The iScan HD uses a serial connection. It has a configurable baud rate, but this driver only supports the highest rate, which is 57,600 baud. It doesn't make sense to run any slower. So you must configure the iScan HD to use this rate, since it defaults to 19,200.
It uses a three wire straight through cable, so you can use a standard 9-pin or a minimal 3-pin serial cable.

Driver Fields

This section lists the fields that the driver makes available, their types, minimum and maximum values, etc...
Name Type R/W Description/Limits
AutoInput Boolean R/W Read/write the auto input mode setting. When set, it does it's own automation selection of the preferred active source.
Brightness Int R/W Read/write the brightness setting. It is a signed value from -100 to +100.
Contrast Int R/W Read/write the contrast setting. It is a signed value from -100 to +100.
Hue Int R/W Read/write the hue setting. It is a signed value from -100 to +100.
Input String R/W Read/write the active input setting. This is an enumerated field, with the values: Unknown, Video 1, Video 2, S-Video 1, S-Video 2, Comp/RGB 1, Comp/RGB 2, Analog Pass, DVI, SDI.
InputAR String R/W Read/write the input aspect ratio. This is an enumerated field with the values: 1.33, Letterbox, 16x9, Preset.
Power Boolean W Powers the device on (True) or puts it into standby mode (False).
PowerLED String R/W Read/write the power LED setting. This is an enumerated field with the values: Off, On, Auto.
ProtoVersion String R A read-only field that indicates the control protocol version.
SignalType String R A read-only field that indicates the current sensed signal type.
