{\bf V1.2}
\begin{itemize}
\item fixed typo in Command Desription in step 1.1
\item changed HW TLM verifiers in step 1.1 and 2.1 so that the heater
current and voltages are the primary verifiers
\item added a note that the HW serial digital verifiers are only valid
if one side of the DPA is on
\end{itemize}

{\bf V2.0}
\begin{itemize}
\item ACIS Team signed-off version
\item changed TLM Description in step 2.2 to ``DA Htr Current B ''
