"""A wrapper around the :class:`~.benhw32.Bentham32` class.
This class can be used with either a 32- or 64-bit Python interpreter
to call the 32-bit functions in ``benhw32_cdecl.dll``.
The :attr:`~msl.equipment.record_types.ConnectionRecord.properties`
for a Bentham connection supports the following key-value pairs in the
:ref:`connections_database`::
'cfg': str, the path to the System.cfg file [default: None]
'atr': str, the path to the System.atr file [default: None]
If the ``cfg`` and ``atr`` values are not defined in the :ref:`connections_database`
then you will have to call :meth:`build_system_model`, :meth:`load_setup`
and :meth:`initialise` (in that order) to configure the SDK.
Do not instantiate this class directly. Use the :meth:`~.EquipmentRecord.connect`
method to connect to the equipment.
Parameters
----------
record : :class:`~.EquipmentRecord`
A record from an :ref:`equipment_database`.
