\subsubsection{Powering Schemes}
\begin{description*}
\item[External 5V] Connect a 1.5A power supply with not more than 5.5V to the black 3pin input.
\begin{description*}
\item [C21, C22, C24, C25] Replace by 0R (AC coupling for trigger signals)
\item [R8, R9, R10, R11] Replace by proper 100 Ohm termination (AC coupling for trigger signals)
