The ``recv == Device("LTS/RECV/1")`` device controls the RCUs, the LBA antennas, and HBA tiles. Central to its operation are the masks (see also :ref:`attribute-masks`):
- The ``RCU_mask_RW`` attribute is an array of ``bool[N_RCUs]``. It controls which RCUs will actually be configured, when fields referring to RCUs are set.
:RCU_mask_RW: Controls which RCUs will actually be configured when attributes referring to RCUs are written.
- The ``Ant_mask_RW`` attribute is an array of ``bool[N_RCUs][N_Antennas_per_RCU]``. It controls which antennas will actually be configured, when fields referring to antennas are set.
See :ref:`attribute-masks` for how the masks are used.
:type: ``bool[N_RCUs]``
:Ant_mask_RW: Controls which antennas will actually be configured when attributes referring to antennas are written.
:type: ``bool[N_RCUs][N_Antennas_per_RCU]``
Typically, ``N_RCUs == 32``, and ``N_Antennas_per_RCU == 3``.
Typically, ``N_RCUs == 32``, and ``N_Antennas_per_RCU == 3``.
