Specifying Device and Format Information

3-15

dev =

AdaptorDllName: 'C:\My_Adaptor\mydeviceimaq.dll'

AdaptorDllVersion: '4.1 (R2011a)'

AdaptorName: 'mydeviceimaq'

DeviceIDs: {[1]}

DeviceInfo: [1x1 struct]

To view detailed information about the device, view the structure in the

DeviceInfo field. The DeviceInfo field is an array of structures, where each

structure provides detailed information about a particular device.

dev_info = dev.DeviceInfo

dev_info =

DefaultFormat: 'RS170'

DeviceFileSupported: 0

DeviceName: 'MyDevice'

DeviceID: 1

ObjectConstructor: 'videoinput('mydeviceimaq', 1)'

SupportedFormats: {'PAL' 'RS170'}

The following table describes the information in each field, with references to other

sections that provide more information.

Field Description

DefaultFormat Text string that specifies the default format used by the device. You

define the default format when you add the IDeviceFormat object to

the IDeviceInfo object; see “Specifying the Default Format” on page

3-13.

DeviceFileSupported Boolean value that tells whether the device supports device

configuration files (also known as camera files). You use the

setDeviceFileSupport() member function of the IDeviceInfo object

to set this value; see “Configuring Device Configuration File (Camera

File) Support” on page 3-13.

DeviceName Text string that identifies a particular device. You define this value

when you create the IDeviceInfo object; see “Storing Device

Information” on page 3-11.
