\section{Readout timing- maximum frame rate}\label{timing}
IMPORTANT: to have faster readout and smaller dead time, one can configure {\tt{clkdivider}}, i.e. the speed at which the data are read, i.e. 200/100/50~MHz for {\tt{clkdivider 0/1/2}} and the dead time between frames through {\tt{flags parallel}}, i.e. acquire and read at the same time or acquire and then read out.

\section{Loading firmware bitfiles}
\textbf{As a new procedure, the first thing to do is to kill the server on the boards, copy the new one there without starting it.} Note taht failure to do this step before may cause the linux on the baords to crash and not being able to ping it (this if the registers between the old and new firmware change).
This is teh procedure from a terminal;
\begin{verbatim}
for i in beb111 beb070;
do ssh root@$i killall eigerDetectorServer;
scp eigerDetectorServer root@$i:~/executables/eigerDetectorServer ;
ssh root@$i sync; done
\end{verbatim}
A \textbf{bcp} executable (which needs \textbf{tftp} installed on the PC, is needed.
\begin{enumerate}
\item Manual way: you need to press something on the detector. To program bitfiles (firmware files), do a hard reset with a pin/thin stuff in the holes at the very back of the module. They are between the top 7 LED and the bottom 1 and opposite for the other side. Push hard till all LEDs are alternating green and red.
