property settings

The device settings specified in ThorlabsDefaultSettings.xml

If this is an empty dict then you can specify the device_name in the properties field in the Connections Database or you can run the Kinesis software and allow Kinesis to configure the actuator that is connected to the motor controller.

The possible values for device_name can be found in the ThorlabsDefaultSettings.xml file (located in the Kinesis installation folder, e.g., C:Program FilesThorlabsKinesis). as the Name value in one of the <DeviceSettingsType> tags.

Type

dict

static build_device_list()[source]

Build the device list.

This function builds an internal collection of all devices found on a USB port that are not currently open.

Note

If a device is open, it will not appear in the list until the device has been closed.

Raises

ThorlabsError – If the device list cannot be built.

static get_device_list_size()[source]

int: The number of devices in the device list.

static get_device_list(*device_ids)[source]

Get the contents of the device list which match the supplied device IDs.

Parameters

device_ids (int) – A sequence of device ID’s.

Returns

list of str – A list of device serial numbers for the specified device ID(s).

Raises

ThorlabsError – If there was an error getting the device list.

static get_device_info(serial_number)[source]

Get the device information from a USB port.

The device info is read from the USB port not from the device itself.

Parameters

serial_number (str) – The serial number of the device.

Returns

structs.TLI_DeviceInfo – A DeviceInfo structure.

Raises

ThorlabsError – If there was an error getting the device information.

static to_version(dword)[source]

Convert the firmware or software number to a string.

The number is made up of 4-byte parts.

See the get_firmware_version() or the get_software_version() method of the appropriate Thorlabs MotionControl subclass.

Parameters
