\section{Introduction}
\label{sec:intro}
\textcolor{red}{\textbf{block diag. from PTS userguide}}
This document presents the hardware of the TTL to blocking converter system (Figure~\ref{fig:conv-sys-bd}).
A full pulse conversion system consists of three distinct boards:
\begin{itemize}
\item CONV-TTL-BLO -- active front module, containing the circuits necessary
to achieve all functionality of the system
\item CONV-TTL-RTM -- passive rear-transition module (RTM) motherboard, providing the
connections from the CONV-TTL-BLO VME P2 connector to the rear panel
\item CONV-TTL-RTM-BLO -- piggyback board on the RTM, providing the LEMO connectors
pulse LEDs, and the screws to fix the rear panel
\end{itemize}

\textcolor{red}{\textbf{conv-sys diagram and description}}
The CONV-TTL-BLO can be used standalone without any RTM, if no blocking pulse replication
is needed. This board contains all active circuitry needed to implement the functionalty of
the system, from blocking pulse detection and generation, to communication over I$^2$C and
time-tagging via White Rabbit \cite{white-rabbit}.
An RTM system usually consists of both motherboard and piggyback and provide the
connections to input blocking pulses to the CONV-TTL-BLO.
