Whenever a global trigger is generated by the unit, a 48-bit coarse time-stamp is attached to it. This time stamp is based on the internal clock. The unit also records a fine-grain time stamp with 780~ps resolution for each signal involved in the trigger decision.\\
The configuration parameters and data are sent and received via the \href{https://www.ohwr.org/projects/ipbus}{IPbus} which provides a simple way to control and communicate TCA-based hardware via the UDP/IP protocol.\\
The \gls{tlu} is shipped with an \gls{fpga} board already programmed with the latest version of the firmware needed to operate the unit. New features and bug fixes are continuously being implemented by the developing team and it is possible to flash the unit with a new firmware as described in section~\ref{ch:flashFPGA}.\\
The unit requires 12~V to operate. Power can be provided using the circular socket located on the back panel. See section~\ref{ch:backpanelintro} for details on compatible connectors.\\
During normal operation the current drawn by the unit is about 1~A.\\
The internal electronics of the \gls{tlu} require 12~V to operate and will dissipate about 12 W during normal operation.\\
Power should be provided using the socket located on the back panel. See section~\ref{ch:backpanelintro} and \ref{ch:rackmountpanel} for details on compatible connectors.\\
\section{Hardware modules}\label{ch:hardwaretypes}
The unit is provided in two different configurations: a table-top enclosure and a 19"-rack mount enclosure. The difference is only cosmetic; the hardware inside the unit is identical\footnote{With the only exception that the 10"-rack unit has and additional \gls{lcd}.} so the information contained in the rest of this manual apply to both types of \gls{tlu} unless otherwise specified.

\subsection{Table-top unit: front panel}\label{ch:frontpanel}
The front panel of the \gls{tlu} is shown in figure~\ref{fig:tabletop} (top); from left to right, the main elements are:
\begin{itemize}
\item \gls{sfp} cage
\item \gls{sfp} cage. This port can be used to provide timing signals via optical/copper interface. Do not attempt to use this to talk to the \gls{tlu} register as the firmware does not support this mode of operation.
\item 4 \gls{hdmi} connectors for devices under test. Each connector has a \gls{rgb} LED used to indicate the port status (see section~\ref{ch:frontpanelintro}).
\item 1 LEMO connector for \gls{lvds} clock input/output. This is a 2-pin LEMO series 00 connector\footnote{Part number EPG.00.302.NLN. An example of mating part is LEMO FGG.00.302.CLAD35}. A \gls{rgb} \gls{led} indicator is used to signal whether the port is configured as input or output.
\item 6 LEMO Trigger inputs. These are standard 1-pin LEMO connectors\footnote{LEMO EPK.00.250.NN. Mates with any LEMO 00.250 connector}. Each input has a \gls{rgb} \gls{led} indicator.

At the moment of shipping, each \gls{tlu} is pre-configured with the most recent version of the firmware. It is therefore possible to power the unit and start using it almost immediately. The following steps are required to use the unit:
\begin{enumerate}
\item Ensure no \gls{usb} cable is plugged in the unit
\item Power the unit using the provided power supply (+12~V) or an equivalent power supply. The pre-configured firmware will automatically load.
\item Plug an Ethernet cable in the back panel and connect it to the computer used to run the control software. Note that currently the unit uses a pre-defined IP address of 192.168.200.30. In future version of the firmware the address will be configurable.
\item Power the unit. The pre-configured firmware will automatically load.

In future version of the firmware the address will be configurable. Try to ping the IP address of the unit: if the unit responds then the firmware is correctly loaded.
\item Use the control software to configure the unit. In particular, after each power up it is necessary to re-configure the clock chip. See chapter~\ref{ch:controlsw} for details on the software and chapter~\ref{ch:clock} for details on the clock chip.
