UPS (Serial)
============

**From:** `Megatec <https://www.megatec.com.tw/allproducts/>`_

**Class:** :py:class:`herosdevices.hardware.megatec.SerialUPS`


**Driver Quality Index:** stable


Representation of Megatec based uninterruptible power supplies.

Several UPS vendors use the Megatec based controller card. Among them are:
    - AdPoS
    - Green Cell

.. important::

   The devices are quite picky concerning the serial to USB chip. It is known to work with a ``Prolific PL2303``
   chip. Others might work but it is not guaranteed.

.. important::

   Some devices seem to have an incorrectly grounded serial interface, generating massive noise on the output
   line. Check for noise on the output power sockets before installing permanently!

A documentation of the full protocol can be found `here <https://networkupstools.org/protocols/megatec.html>`_.
