class thorlabs_apt_device.devices.bbd.BBD201(serial_port=None, vid=None, pid=None, manufacturer=None, product=None, serial_number='73', location=None, home=True, invert_direction_logic=False, swap_limit_switches=True)[source]

Bases: APTDevice_BayUnit

A class for ThorLabs APT device model BBD201.

It is based off APTDevice_BayUnit configured with a single channel and the the BBD serial number preset in the initialisation method.

Parameters:

  • serial_port – Serial port device the device is connected to.

  • vid – Numerical USB vendor ID to match.

  • pid – Numerical USB product ID to match.

  • manufacturer – Regular expression to match to a device manufacturer string.

  • product – Regular expression to match to a device product string.

  • serial_number – Regular expression matching the serial number of device to search for.

  • location – Regular expression to match to a device bus location.

  • home – Perform a homing operation on initialisation.

  • invert_direction_logic – Invert the meaning of “forward” and “reverse” directions.

  • swap_limit_switches – Swap “forward” and “reverse” limit switch values.
